ITSCM (information technology service continuity management) may assist customers with preparing in case a disaster strikes critical Information Technology (IT) services utilized to conduct core business functions and systems. By implementing the best IT service continuity management practices and standards, ITSCM may be kept up-to-date and may periodically test the ITSCM plans describing the actions to be taken to recover the vital business functions and systems. The two key deliverables may include: (1) advising customers via data analyses; and (2) managing the risks connected with new incidents.
Embodiments of the present invention disclose a method, computer system, and a computer program product for estimating the probability of invoking information technology (IT) disaster recovery at a location based on an incident risk. The present invention may include receiving a piece of data associated with an incident at the location. The present invention may also include estimating a similarity value associated with the incident based on a plurality of past incidents from a knowledge base. The present invention may then include receiving a plurality of mined data based on the location (e.g., architecture, network and device configurations, workloads, weather, social media posts). The present invention may further include predicting the incident risk to the location based on the received plurality of mined data and the estimated similarity value to the plurality of past incidents.
These and other objects, features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings. The various features of the drawings are not to scale as the illustrations are for clarity in facilitating one skilled in the art in understanding the invention in conjunction with the detailed description. In the drawings:

The following described exemplary embodiments provide a system, method and program product for estimating one or more incident risks that trigger a disaster recovery invocation. As such, the present embodiment has the capacity to improve the technical field of information technology (IT) service continuity management by assessing the likelihood of a disaster recovery invocation for the appropriate team to be notified, with a reduced response time, to begin to shift workloads from a primarily processing center to a data recovery center. More specifically, the disaster recovery invocation program may identify the incident based on the data received, and then analyze the data properties included in the incident. The disaster recovery invocation program may then estimate the description similarities based on historical classification of other data from a tickets database. Then, the disaster recovery invocation program may commence a classification component, then a weather prediction and social media analytics component, and then a predicting risk component in which the disaster recovery invocation program may assess the risk of disaster recovery invocation.
As previously described, ITSCM (Information Technology Service Continuity Management) may assist customers with preparing in case a disaster strikes critical Information Technology (IT) services utilized to conduct core business functions and systems. By implementing the best IT service continuity practices and standards, ITSCM may be kept up-to-date and may periodically test the ITSCM plans describing the actions to be taken to recover the vital business functions and systems. The two key deliverables may include: (1) advising customers via data analyses; and (2) managing the risks connected with new incidents. The purpose of incident analysis may be to understand the risk connected with the incident in terms of possible disaster recovery invocation to be implemented, or other possible scenarios (e.g., major incident declaration).
Additionally, the risk may be directly connected with locations. The location may be well equipped with systems and methods to prevent disaster (e.g., Server Recovery Manager), which may automatically recover data in another location that is not at risk. A Server Recovery, for example, may in fact cause the risk as the typical recovery center is less powerful in terms of computational power than the original center. Typically, a recovery center may have 20% of the computational power compared to the original data center and may handle only critical business. Nevertheless, the disaster recovery invocation program may not consider the risk of disaster itself. Instead, the disaster recovery invocation program may estimate the risk connected with disaster recovery invocation that may be implemented, which may, or may not, lead to real site recovery.
Currently, the disaster recovery invocation may take a significant amount of time and may be reactionary to such events. Therefore, it may be advantageous to, among other things, estimate the probability of disaster recovery invocation that may be implemented by corroborating historical classification of infrastructure incidents, high severity incidents/data center infrastructure failure, security incidents and physical breach of a data center, data center infrastructure protection level, business risk connected with importance of IT environment, social media data, acts of war or terrorism, pandemic situations, and weather and natural disaster data. The disaster recovery invocation program may also stop (or abort) the disaster recovery invocation preparation or execution based on a proposed classification, and reduce a probability of missing the IT environment recovery Service Level Agreement by improving recovery time through the utilization of a simulation engine to proactively assess the invocation to be implemented based on confidence level. The disaster recovery invocation program may further include a continual learning improvement component, which stores the results of the calculation, and may utilize the results of the calculation to modify the incident knowledge base, when specific business impact occurs.
Additionally, the business effect of predicting high risk may include a raised awareness of upcoming incidents that may cause disaster recovery invocation in IT Service Continuity and Resiliency teams, the notification of important contacts (e.g., internal account management and external client representatives responsible for disaster recovery) and start internal preparation (e.g., mobilize and activate technical teams necessary to facilitate the resumption of time-sensitive business operations). The disaster recovery invocation program may continually assess and report Incident impact in accordance with the Service Provider Disaster Recovery Plan (i.e., extent of damage and disruption to the Services and business operations), as well as may prepare to invoke and execute additional activities set out within the relevant Service Provider Disaster Recovery Plan, report status of the activities being undertaken, and provide links to appropriate procedures and planning documents necessary to effectively execute the recovery.
According to at least one embodiment, the disaster recovery invocation program may estimate the risk of incidents (i.e., incident risks) that may trigger disaster recovery invocation. The invocation of the disaster recovery may be initiated when (a) a data processing site is unreachable, (b) a particular data processing service is unavailable, and (c) key personnel are unavailable, making the capabilities of the normal data processing difficult. The present embodiment may include predicting the likelihood of any of these situations and may notify the appropriate team to commence the activities to shift workloads from a primary processing center to a data recovery center. The notification may save a considerable amount of time (e.g., several hours) of processing time and may avoid a considerable amount of money in business losses (e.g., millions of dollars) for little cost and effort.
According to at least one embodiment, in addition to the risk notification, the disaster recovery invocation program may provide links to appropriate procedures and planning documents utilized to effectively execute the recovery. The present embodiment may include a mechanism designed to assess the likelihood of the need for disaster recovery invocation, which utilizes natural language processing (NLP) along with machine learning (ML) techniques to increase the accuracy of the risk assessment.
According to at least one embodiment, there may be several input data sources utilized by the disaster recovery invocation program to calculate the risk associated with the loss of the critical processing for certain situations (e.g., high severity incidents, data center infrastructure failure, security incidents and physical breach of a data center, data center infrastructure protection level, business risk connected with importance of IT environment, social media data, acts of war or terrorism, pandemic situations, or weather and natural disaster data). To assess the need to invoke a disaster recovery option, the present embodiment may include the utilization of the data sources along with historical classification of incidents which may be treated as a knowledge base. Based on redundancy and pattern analysis, the disaster recovery invocation program may compare a new data center, security incident and situation data to a knowledge base and may assess the likelihood of necessity to invoke disaster recovery procedures. The cognitive solutions (e.g., natural language classification and continual learning) may be included as a part of the disaster recovery invocation program.
According to at least one embodiment, the disaster recovery invocation program may focus on disasters that lead to the site being unreachable, service unavailability or personnel unavailability, and the disaster recovery invocation program may be influenced by non-IT factors (e.g., external factors). Therefore, the disaster recovery invocation program may include, as a part of a risk assessment, additional data from weather monitoring (e.g., focusing on territorial connections between location and weather predictions), social media by searching for disaster mentions or acts of terrorism, pandemic notification, or data center breach.
According to at least one embodiment, the disaster recovery invocation program may design a simulation engine. The disaster recovery invocation program may include three parallel levels of confidence used for situation classification; where alerts may be transmitted from additional data inputs, where data protection level and business risk connected with the level of inclusion for the IT environment are defined, and where incidents are logged in a ticketing system. Using a predictive analytics engine, the disaster recovery invocation program may determine the next steps by identifying a plurality of relevant information from the received data associated with the three parallel levels of confidence.
Referring to
The client computer 102 may communicate with the server computer 112 via the communications network 116. The communications network 116 may include connections, such as wire, wireless communication links, or fiber optic cables. As will be discussed with reference to
According to the present embodiment, a user using a client computer 102 or a server computer 112 may use the disaster recovery invocation program 110a, 110b (respectively) to estimate the risk of incidents that trigger disaster recovery invocation. The disaster recovery invocation method is explained in more detail below with respect to
Referring now to
At 202, an incident is received. Utilizing a software program 108 on the user's device (e.g., client computer 102), data associated with an incident (x) may be transmitted as input into the disaster recovery invocation program 110a, 110b, via the communication network 116. The incident may include an incident ticket, an infrastructure ticket, an infrastructure failure, a security incident, a weather alert, a social media warning, or any other form of notification associated with the incident. The disaster recovery invocation program 110a, 110b may utilize a predictive engine to identify relevant information and/or data associated with the incident (e.g., a date of reporting incident date), at least one reporting data center, an incident summary (e.g., topic of the incident), a description of the incident (i.e., incident description), and other optionally relevant information.
For example, IT representative ABC is notified that the disaster recovery invocation program 110a, 110b received an incident notification, Incident Ticket #XYZ2017, that Server XYZ has malfunctioned in Data Center X located approximately 3,000 miles away from the headquarters. The incident notification stated the following:
Incident Date: Apr. 10, 2019 at 4:45 am.
Incident Description & Summary: Server XYZ has abruptly stopped operating.
Reporting Data Center Location: Data Center X located in Miami, Fla.
Then, at 204, the disaster recovery invocation program 110a, 110b determines whether the data properties are structured. The disaster recovery invocation program 110a, 110b may utilize one or more external engine or technologies to determine whether the data properties associated with the received incident are structured. Structured data may refer to any data that resides in a fixed field within a record or file (e.g., photos and graphic images, videos, streaming instrument data, webpages, Portable Document Format (PDF) files, PowerPoint presentations, emails, blog entries and word processing documents), and may include defined data types whose pattern causes the data to be easily searchable. Structured data, for example, includes a start date, a call code, a host name, a region name, and a site name. Structured data may be stored in dedicated fields in a defined data format in the incident record. The defined data format may include, for example, a series of date formats (e.g., dd-mm-rrrr, mm-dd-rrrr, rrrr-mm-dd), and a call code (e.g., define a list of possible call codes in the incident). The disaster recovery invocation program 110a, 110b may utilize a search engine to parse through the data associated with the incident to determine whether the data properties include a defined data format, which is indicative of structured data.
Unstructured data, however, may include data that is not easily searchable (e.g., text written by human as a comment). For example, unstructured data includes streaming data coming from social media platforms, e-mail messages, word processing documents, comments inserted by a human as text, and business interactions, such as questions and responses exchanged by different technical divisions. In some embodiments, files with an internal structure may be considered unstructured, since the data within the files may fail to clearly fit within one or more fixed fields in a rational database (e.g., database 114).
If the disaster recovery invocation program 110a, 110b determines that the data properties are not structured (i.e., unstructured) at 204, then the relevant information is extracted at 206. The disaster recovery invocation program 110a, 110b may utilize one or more external technologies (e.g., UIMA (Unstructured Information Management Architecture) standard) to parse through the unstructured data properties associated with the received incident, and to extract the incident summary and description of the incident, which may be provided in plain text (i.e., text provided by human operator as description of the technical event which happened in the infrastructure and the tasks executed to resolve the situation).
In at least one embodiment, the disaster recovery invocation program 110a, 110b may, in the case of automated resolution, provide plain text as structured data with time stamps. In some embodiments, human technicians may be utilized to convert unstructured data into structured data.
In another embodiment, the ticketing systems used to log and store incident tickets may include some dedicated fields (e.g., Title, Summary, Description, Technical Description, Resolution). These fields may be analyzed and utilized to determine what type of data are included based on the pre-defined field descriptions. The field naming, however, may differ for different tools. The disaster recovery invocation program 110a, 110b may define a list of most typical field names to match the field names with the content. The incident summary and description may usually be provided as text inserted by the human operator into the ticketing system. The technical description may have some structured form (e.g., a template) used by technical teams to be filled each time an incident is reported. The template may include a field for a description of the situation.
In at least one embodiment, the disaster recovery invocation program 110a, 110b may include semi-structured data, which may include a cross between the structured data and unstructured data. The semi-structured data may include a type of structured data that lacks the strict data model structure. With semi-structured data, tags or other types of markers may be used to identify certain elements within the data, without the rigid structure. For example, a word processing software can include metadata showing the author's name and the date created, with the bulk of the document being considered unstructured text. In another example, emails include a sender, a recipient, a date, a time and other fixed fields, added to the unstructured data of the email message content and any attachments.
In at least one embodiment, the disaster recovery invocation program 110a, 110b may utilize technologies or an external engine to process and store the unstructured data.
Continuing the previous example, if the disaster recovery invocation program 110a, 110b determined that the data properties associated with Incident Ticket #XYZ2017 were not structured, then the relevant information, namely incident summary and description, would be extracted from the data associated with the incident.
Regardless of whether the disaster recovery invocation program 110a, 110b determines that the data properties are structured at 204, or the incident-related data is extracted at 206, the similarity value is estimated at 208. For structured data properties, the disaster recovery invocation program 110a, 110b may parse through the data associated with the received incident to identify and extract the incident date, as well as optionally relevant information (e.g., call code, hostname, region name, site name). The relation between incident summary, description and site name, hostname and other optionally relevant information may be utilized to assess the risk and make a decision about whether disaster recovery should be invoked.
In at least one embodiment, the disaster recovery invocation program 110a, 110b may not receive the optionally relevant information. Therefore, the disaster recovery invocation program 110a, 110b may utilize the data included in the description and resolution text fields to calculate the optionally relevant information. For example, in 2017, Hurricane Maria struck a data processing center location in the US. The center was flooded, but due to some additional factors, like site protection mechanisms, the disaster recovery was not invoked. Based on the incident summary and description that referred to a malfunctioned server and information indicating that the data center was located in the path of Hurricane Maria, the existing ITSCM plan was still unable to make a final decision. If the disaster recovery invocation program 110a, 110b had been implemented, the optionally relevant information, such as the site name, would have been utilized to determine (based on created knowledge base about data center location) if this data center location had an appropriate level of protection mechanisms (e.g., natural disaster risk-free locations, detection sensors, strengthened construction). The region name may also have been utilized to compare with other similar incidents in the same region, or within a certain proximity of the region.
In another example, hurricanes, in addition to similar natural disasters, such as floods, may influence the nearby area where a power station that provides the electricity to one or more data centers is located. Based on site location and region name, the disaster recovery invocation program 110a, 110b can form a link between the influenced region and data center location. Based on site name, the disaster recovery invocation program 110a, 110b may determine (based on created knowledge base about data center) that the data center is equipped with a diesel electric generator. Therefore, the disaster recovery invocation program 110a, 110b can assess the risk of electricity loss more accurately, and stop disaster recovery invocation since invoking disaster recovery is not necessary at that time.
Additionally, for structured and unstructured data properties, the disaster recovery invocation program 110a, 110b may utilize a text cleaning function (e.g., Cln(text)). By utilizing the text cleaning function, the disaster recovery invocation program 110a, 110b may split the plain text (e.g., ticket description joined with ticket resolution) by spaces, remove any stop words (e.g., some common short function stop words include “is”, “at”, “the”, “which”), remove any host names based on the configuration management database (CMDB) information, remove any words with three or more consecutive vowels, remove any numbers, and other cleaning text steps.
For both structured and unstructured data properties, the disaster recovery invocation program 110a, 110b may retrieve past historical data associated with past incidents (i.e., existing incidents) from a tickets database 210 (e.g., database 114). The tickets database 210 may include a knowledge base of incident tickets that were identified in history (or past data) as incidents which caused or might cause disaster recovery invocation. The received incident (x) may then be compared with each existing incident (y) from the tickets database 210 (KB) by utilizing the Cnt(x,y) function. Then, the disaster recovery invocation program 110a, 110b may define:
Swc(x,y)=(Cnt(Cln(x),Cln(y)))/Cln(x),
The disaster recovery invocation program 110a, 110b may then utilize a classifier to perform an analysis of the plain text included in the received incident (x) to estimate the description similarities with other past historical data associated with past incidents (y) retrieved from the tickets database 210.
In at least one embodiment, the classifier may perform a contextual analysis of the plain text based on natural language processing (NLP) techniques (e.g., text embeddings) (i.e., NL classifier) to analyze the text included in the received incident, as well as consecutively or simultaneously search the existing incidents from the tickets database 210 to identify similarities in the context or text. The NL classifier may then compare the identified context from the received incident with the identified context from the existing incidents in the tickets database 210.
In at least one embodiment, the classifier may perform a keyword analysis (i.e., keyword analyzer) on the incident-related data or structured data properties associated with the received incident. The keyword analysis may include individual words, or phrases (e.g., including more than one word in a consecutive sequence). The keyword analyzer may consecutively or simultaneously search the tickets database 210 to identify keywords in each of the existing incidents. The keyword analyzer may then compare the identified keywords from the received incident with the identified keywords from the existing incidents in the tickets database 210.
Additionally, the disaster recovery invocation program 110a, 110b may apply weight (wgt_w) for each term (e.g., keyword, phrase), differing the weight for each term, to identify the significance of the term in connection with the risk assessment by analyzing whether the term is included in the defined terms (K) in the tickets database 210. The disaster recovery invocation program 110a, 110b may then define weight(w) for each term as follows:
weight(w)=wgt_w ifw in K
weight(w)=0 otherwise
Then
Kwa(x)=Max(weight(w)) forw in x
In at least one embodiment, the classifier may generate a score as a percentage (e.g., normalized quantity ranging from 0-100%) associated with the similarity of the received incident to each existing incident in the tickets database 210 (i.e., a similarity value). The higher the percentage, the greater the similarity between the received incident and the existing incident. In some embodiments, the classifier may generate a score as a numeric value (e.g., normalized quantity ranging from 0-1, 0-10, 0-100) associated with the similarity of the received incident to each existing incident in the tickets database 210 (i.e., similarity value). The higher the score or similarity value, the greater the similarity between the received incident and the existing incident.
In an embodiment, the score may be based on the defined weight for each term as determined by the disaster recovery invocation program 110a, 110b.
Additionally, the classifier may sort and rank the similarity value (i.e., weight and/or score) for each existing incident. The classifier may then generate a list with the similarity value associated with the received incident and each existing incident. In at least one embodiment, the generated score may be compared with a previously determined threshold level (e.g., a default level is 75% out of 100%, 0.75 out of 1, 7.5 out of 10, 75 out of 100). If the generated score fails to satisfy the previously determined threshold level, then the classifier may classify the received incident as dissimilar (i.e., not similar) from the existing incident, and may exclude the corresponding existing incident from the list. If the generated score satisfies the previously determined threshold level, then the classifier may classify the received incident as similar to the existing incident, and may include the corresponding existing incident in the list.
In at least one embodiment, the default threshold level may be re-configured by an administrator on a case-by-case basis, or based on a pattern over a period of time. For example, if a user determines that the received incidents and existing incidents have a high level (or degree) of similarity that may exceed 75% for a majority of the existing incidents, then the user may prefer to increase the threshold level to decrease the number of similar existing incidents included in the list.
In some embodiments, the classifier may be re-configured to select a certain number (e.g., top 10, top 20) of similar existing incidents to include in the list based on the ranking of the existing incidents.
The classifier may then transmit the generated list, via the communications network 116, to the disaster recovery invocation program 110a, 110b.
Continuing the previous example, the text associated with the Incident Ticket #XYZ2017 is cleaned to remove spaces, numbers (not associated with the relevant information), and stop words. Then, the disaster recovery invocation program 110a, 110b generates the following text for Incident Ticket #XYZ2017:
Apr. 10, 2019 4:45 am
Server XYZ abruptly stopped operating
Data Center X Miami Fla.
Then, the text associated with Incident Ticket #XYZ2017 is compared to more than 200 past incidents from the tickets database 210. The disaster recovery invocation program 110a, 110b then utilizes a keyword analyzer to identify keywords. The keyword analyzer then identifies keywords “Server XYZ”, “abruptly stopped operating”, “Miami” and “Florida”, which 5 past incidents also have included their description. The classifier then estimates a similarity value to each of the 5 past incidents with the identified keywords. The classifier then ranks and sorts the similarity values with the corresponding past incidents, and generates the following list that is transmitted to the disaster recovery invocation program 110a, 110b:
Incident Ticket #ABC1997—95%
Incident Ticket #DEF1998—92%
Incident Ticket #GHI1999—91%
Incident Ticket #JKL1999—90%
Incident Ticket #MN02016—85%
Then, at 212, the classification component is commenced. Utilizing the classification component, the disaster recovery invocation program 110a, 110b may classify the received incident into a category (e.g., one of n classes) based on the similarities between the received incident and the existing incidents in the tickets database 210. The disaster recovery invocation program 110a, 110b may then analyze the existing incidents included in the generated list. Based on the classes or categories of the existing incidents, the disaster recovery invocation program 110a, 110b may determine the classification of the received incident. For example, if a majority of the similar existing incidents are classified as X, then Received Incident A is classified X.
In at least one embodiment, the disaster recovery invocation program 110a, 110b may utilize the data center infrastructure protection level and the business risk connected with the importance of the IT to determine the appropriate class or category to classify the received incident. Business risk for the appropriate data center (i.e., site) may be evaluated based on the importance of the IT infrastructure hosted. For example, Data Center W in Warwick, United Kingdom, where multi-client infrastructure is hosted, is working at nearly 100% capacity and even small defect can largely impact the final customer. As such, the business risk for such a data center is very high. However, Data Center B, which is a backup data center dedicated to one customer, is not an integral part of the business since Data Center B is operated in a standard way and end user utilization is small. Data Center B is a safe place to keep backup data in case something happens to the original data center, Data Center W. Therefore, the business risk for Data Center B is low because Data Center B can be recovered, even if disaster strikes the site, without direct impact to the final customer.
In another example, there is Server A which is responsible for transaction processing for a big customer such as a bank, and Server C, which is a test environment used for internal purposes to test current development. As such, the business risk for the Server A would be high, and for Server C would be low.
Continuing the previous example, since each of the past incidents included on the generated list are a part of class 7, then the disaster recovery invocation program 110a, 110b classified Incident Ticket #XYZ2017 as a part of class 7, which is high risk because the Server XYZ stores a majority of the confidential memorandums circulated within a 10 year time period by the company.
Then, at 214, the weather and social media analytics component is commenced. The weather and social media analytics component, which is divided into two sub-components: weather analytics sub-component and social media analytics sub-component, may analyze the current situation (e.g., weather or social media alerts) for a particular location (e.g., location of interest). Utilizing the weather analytics sub-component, the disaster recovery invocation program 110a, 110b may identify probable risks connected with upcoming weather incidents (e.g., hurricane or flood). By utilizing an external weather prediction system independent from the end user, the disaster recovery invocation program 110a, 110b may receive as input the upcoming weather incidents for a previously determined period of time (e.g., default is the next seven days or 168 hours) for the location of interest.
Utilizing the social media analytics sub-component, the disaster recovery invocation program 110a, 110b may collect any alerts or social behaviors (e.g., protests, manifestations) from the internet, including social media posts, breaking news associated with various sources, local and regional news sources, and blogs. The disaster recovery invocation program 110a, 110b may utilize an external search engine to search or crawl through the internet, including social networks and other sources, to identify any alerts or social behaviors that may invoke a disaster recovery within a previously determined period of time (e.g., default is the next seven days or 168 hours) for the location of interest. The search engine may then transmit the received data associated with alerts or social behaviors in any social network to the disaster recovery invocation program 110a, 110b via the communications network 116.
In at least one embodiment, an administrator may reconfigure or modify the settings to change the previously determined period of time for the weather and social media analytics component. In some embodiments, the disaster recovery invocation program 110a, 110b may automatically modify the previously determined period of time based on the patterns of previously determined periods of time, or based on an upcoming weather incidents or social media posts predicted shortly after previously determined period of time. For example, if the previously determined period of time is three days or 72 hours and, based on social media posts, internet blogs and a weather forecasting program, Hurricane K is estimated to make landfall at the location of interest in 90 hours as a category four hurricane, then the disaster recovery invocation program 110a, 110b may automatically adjust the previously determined period of time to include the next 90 hours, instead of 72 hours.
Continuing the previous example, based on the search engine, social media sources are indicating that there are several power outages throughout Miami, Fla. due to extremely hot and humid weather that the area has been experiencing for the past five days. In addition, the weather alerts have indicated that the current temperature at the location of Data Center X is more than 97 degrees Fahrenheit with a humidity of 100%.
Then, at 216, the hidden trials analysis component is commenced. Utilizing the hidden trials analysis component, the disaster recovery invocation program 110a, 110b may search a past disaster recovery invocation database 218 (e.g., database 114) for connections or hidden patterns from the data associated with additional factors that may lead to the unavailability or unreachability of a site (i.e., location of interest), service and/or personnel. The past disaster recovery invocation database 218 (i.e., past DRI database or knowledge base) may include past experiences of disaster recovery invocation in which the disaster recovery was or was not invoked. For example, in Data Center N there was a reoccurring issue affecting a large customer, when incidents were logged for transaction processing servers, the transaction processing servers would stop unexpectedly. Due to a high level of importance for IT, the disaster recovery invocation would commence for several of the servers, since the servers were unreachable. The same issue occurred a couple of times. When an investigation was performed, the servers were discovered to have been corroded (i.e., rusty metal). Since the servers were quite new, corrosion was highly unexpected. After further investigation, a determination was made that the corrosion was caused by a change in the air composition provided by the air conditioner to the room where these servers resided. The new vendor provided different air filters that caused an accumulation of sulfur in the air which caused the damage in the servers. Such an incident may be included in the past DRI database 218 for the disaster recovery invocation program 110a, 110b to assess the risk of incident more accurately by discovering the hidden trial as a change of the sulfur level registered by the digital sensors in the area where servers reside.
Continuing the previous example, the disaster recovery invocation program 110a, 110b searches the past DRI database and discovers an incident in which poor air humidity, due to inoperable fans and cooling systems at the location of Server XYZ, was linked to the abrupt inoperability of Server XYZ in the past. There is no alert or information indicating that no one will be present at Data Center X, or that access to Data Center X may be limited or restricted.
Then, at 220, the predicted risk component is commenced. Utilizing the predicted risk component, the disaster recovery invocation program 110a, 110b may assess the risk of disaster recovery invocation as a function of the mined data (including weather analytics, social media alerts and data derived from the past DRI database (if any)) and estimated similarity value. The disaster recovery invocation program 110a, 110b may utilize the additional inputs function, AdIn_i( ), for alert (a_i) to assess the risk. AdIn_i( ) function is defined for each (i) respectively if one of the following situation takes place: (1) there is a high severity incident(s)/data center infrastructure failure connected to the considered incident, then (a) there is a security incident(s) or physical breach of a data center, (b) data center infrastructure protection level is defined and can be used, (c) business risk connected with importance of IT environment is defined and can be used, and/or (d) social media data, acts of war or terrorism, pandemic situations and weather and natural disaster data can be assessed based on alerts.
In at least one embodiment, the disaster recovery invocation program 110a, 110b may define a function, AdIn_i(a), assuming a is an existing alert for the location of interest, as a numeric value from a normalized range [0,1] depending on the significance of the alert. The function may be a higher value for more significant alerts.
The disaster recovery invocation program 110a, 110b may then define the risk adjustment function as follows:
Rdr(x)=1−exp[−(SwcM(x)+Kwa(x)+Σ(AdIn_i(a_i))){circumflex over ( )}2/2]
This number represents the risk for an incident to cause a disaster recovery invocation, which is in the range [0,1] calculated based on the reverse normal distribution function. In at least one embodiment, the greater the values of SwcM(x), Kwa(x), AdIn_i( ), then the closer the risk value is to 1. However, the lesser the values of SwcM(x), Kwa(x), AdIn_i( ), then the closer the risk value is to 0.
The disaster recovery invocation program 110a, 110b may then utilize a defined risk threshold (t), which may be used as a filter for only incident risks that are considered high, or when the Rdr(x)>t, since the value t depends on the considered data center. The defined risk threshold may be previously provided by an end user, or administrator, to the disaster recovery invocation program 110a, 110b.
Continuing the previous example, the assessed risk for Server XYZ located at Data Center X is 0.75 out of 1.0. When compared to the defined risk threshold of 0.69, the assessed risk of Server XYZ is considered high, since 0.75 is greater than the defined risk threshold of 0.69. Therefore, disaster recovery is invoked on Server XYZ located at Data Center X in Miami, Fla.
In at least one embodiment, the disaster recovery invocation program 110a, 110b may include a predicted risk database and continual learning improvement component (e.g., database 114) in which the results of the calculations may be stored and may be later utilized to modify the tickets database 210 (e.g., Rdr(x)>t and business impact occurs).
The functionality of a computer may be improved by the disaster recovery invocation program 110a, 110b because the disaster recovery invocation program 110a, 110b may estimate the probability of disaster recovery invocation by corroborating historical classification of infrastructure incidents, high severity incidents/data center infrastructure failure, security incidents and physical breach of a data center, data center infrastructure protection level, business risk connected with importance of IT environment, social media data, acts of war or terrorism, pandemic situations, and weather and natural disaster data. The disaster recovery invocation program 110a, 110b may also stop (or abort) the disaster recovery invocation preparation or execution based on the proposed classification, and reduce a probability of missing the IT environment recovery Service Level Agreement by improving recovery time through the utilization of a simulation engine to proactively assess the invocation to be implemented based on confidence level. The disaster recovery invocation program 110a, 110b may further include a continual learning improvement component, which stores the results of the calculation, and may utilize the results of the calculation to modify the incident knowledge base, when specific business impact occurs.
The technical actions performed by the disaster recovery invocation program 110a, 110b may further improve the recovery time (through added and early awareness, expanded back-out plans and preparation actions), and may reduce the disaster recovery failure probability.
The disaster recovery invocation program 110a, 110b may further improve computer functionality by being independent from whether a real disaster occurs or not since the occurrence of a natural disaster may have minimal, if any, effect on the location of interest and therefore the IT environment may not need any disaster recovery invocation, or in the reverse way, disaster recovery invocation may be necessary even though there is no natural disaster. As such, the disaster recovery invocation program 110a, 110b may depend on the business risk connected with the importance of the IT environment, site protection level, client needs and additional factors which are uniquely assessed by the disaster recovery invocation program 110a, 110b. For example, a hurricane struck a data processing center (i.e., data center) location in the US. The center is flooded. However, due to some additional factors like site protection mechanisms, the disaster recovery invocation was not needed.
Additionally, in the present embodiment, the disaster recovery invocation program 110a, 110b may include additional factors that are not generated due to a natural disaster. These additional factors may include device unavailable incident tickets from a server or network that cannot be recovered in a short time interval, security breaches that may impact critical business components in the data center, or terrorist threats (e.g., bomb threats). The disaster recovery invocation program 110a, 110b may utilize these factors to determine if the protocol associated with the disaster recovery should be invoked.

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Analytics as a Service (AaaS): the capability provided to the consumer is to use web-based or cloud-based networks (i.e., infrastructure) to access an analytics platform. Analytics platforms may include access to analytics software resources or may include access to relevant databases, corpora, servers, operating systems or storage. The consumer does not manage or control the underlying web-based or cloud-based infrastructure including databases, corpora, servers, operating systems or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.
