In order for an individual or business entity to prepare a computer resource utilization strategy, it is important to understand current usage patterns along with relevant trends so that any additional needed capacities can be anticipated in advance of their need. For example, an individual who routinely adds 5 GB of photographs to their disk drive should know that the remaining 10 GB of free disk space will be gone in two months. With this knowledge, the user can anticipate the need and therefore buy a new disk drive within the two months and prior to the actual need.
Computing resources are typically monitored at a technical level by examining low-level attributes such as CPU capacity, memory, and disk space. System and network status are made available to IT administrators through monitoring dashboards, and exceptions may be communicated through alerts and messages (such as SMS alerts).
Businesses are increasingly reliant on software-as-a-service- (SaaS-) based services (like Salesforce, Box.net and Dropbox services) for mission-critical infrastructure. There is the need to monitor and optimize service usage aside from access to the low-level underlying technology resources in a cloud-based environment.
Optimal use of cloud-based services are generally dependent on three factors: usage patterns, technical constraints, and business constraints. These are defined as follows. Usage patterns may incorporate usage patterns for individuals, for individuals in a group, and for the group as a whole. Usage patterns may include values associated with: frequency of access to the SaaS-based service, volume of access requests to the service or supporting application program interfaces (APIs) (e.g., uploading and downloading content) and interactions with different types of content (e.g., files, contacts, plans).
Examples of technical constraints could include the number of API requests/hour, individual and group limits on storage capacity, network bandwidth, and processor bandwidth. Business constraints consider different business models and billing structures that include, e.g.: subscription based service pricing, tiered pricing, per use pricing, and per user pricing.
What is needed is a method for dynamically optimizing utilization of SaaS-based services based upon a multiplicity of factors including usage patterns, technical constraints, and business account parameters.
An SaaS Broker and associated method are provided for dynamically optimizing utilization of SaaS-based services based upon a multiplicity of factors including usage patterns, technical constraints, and business account parameters. Since the SaaS Broker has access to, or can obtain, a wide range of information about the services offered as well as usage patterns of the service users, an optimum system can be maintained, particularly with regard to expandable cloud services.
Based on the analysis of the usage patterns, the technical restrictions, and/or the business restrictions, the SaaS Broker can predict how soon the technical and/or business restrictions will be reached. When there are multiple cloud services, not all of them will reach their technical restrictions at the same pace. Since the cloud/SaaS Broker has a view across all cloud services and their usage, it can anticipate how fast the technical and/or business restrictions are reached and offer off loading strategies. Furthermore, by incorporating the respective business strategies and constraints into the decisions, an optimum solution can be obtained from both a technical and a business standpoint.
The technical restrictions can deal with aspects related to capacity, such as processor capacity, storage capacity, bandwidth capacity, architectural constraints, such as protocol-related issues, etc. The business restrictions can deal with aspects such as costs (per user, per unit (storage, processor, network bandwidth), per subscription, and also pricing tiers, geographic proximity, availability (e.g., only available during day-time business hours), etc.).
Accordingly, a method is provided for optimizing future resource usage in a cloud environment comprising first and second cloud services, each cloud service being associated with at least one of technical and business restrictions defining a maximum capacity, the method comprising: monitoring current usage patterns of the cloud services; predicting future usage patterns based on the monitored usages; calculating an estimated future time to reach a technical or business restriction for the first cloud service based on the predicted future usage patterns; and adjusting, at a later time associated with the estimated future time, the maximum capacity associated with at least one of the first cloud service and the second cloud service based on the calculation of the estimated future time.
An appertaining system and software media comprising instructions for executing the method are also provided.
The users have individual accounts within the services. In Box, their accounts are managed and paid for under a single corporate account (i.e., there are heterogeneous billing relationships). In Dropbox, each user has a separate account which is individually billed to the company. The users store project files in either Box or Dropbox (since both services provide similar file storage capabilities).
Bob U1, John U2, and Jane U3 have enabled an SaaS Broker to access their accounts (through a mechanism like OAuth) for the purpose of indexing their content (for example). The SaaS Broker monitors the service usage of each user individually, and also, in aggregate across the company. With knowledge of how users interact with the two services, the SaaS Broker can proactively warn the users of impending limits to their use of the services (for example, running out of storage capacity or reaching a subscription threshold, such as number of concurrent users).
By leveraging the SaaS Broker's perspective across services, the broker can project capacity needs and suggest alternative services or actions, for example, moving files from an active project to Dropbox because the company's group account has spare capacity. Thus the SaaS Broker can perform content and context-sensitive predictive resource estimation across heterogeneous cloud-services.
As illustrated in
The following example illustrates how service optimization might work in the context of file storage. In this example, there are two file storage services: Box and Dropbox. In the business model for the Box service, accounts are priced by storage tiers (i.e., volume of data stored in bytes and priced at various volume thresholds). In the business model for the Dropbox service, the accounts are priced by a numbers of documents stored (irrespective of their size).
With regard to the Box service, the company has a Basic account with a 20 GB threshold. It adds documents to the Box service at an average rate of 1 GB/week (comprised of 100 documents/week). Therefore, a predictive algorithm determines that the company will reach capacity in the Box-Basic account in approximately 20 weeks (critical date is Date 2).
With regard to the Dropbox service, the company also has a Basic account with a 500 document threshold. It adds documents to the Dropbox service at an average rate of 50 documents/week (comprising 2 GB/week). Therefore, a predictive algorithm determines that the company will reach capacity in the Dropbox-Basic account in approximagely 10 weeks (critical date is Date 1).
The SaaS Broker identifies available options in advance of the earliest critical date 10 weeks out (Date 1) so that any solutions having a lead time can be implemented before actually reaching the critical date Date 1. One option identified is that when the first critical date (Date 1) is reached, documents can be sent over to the Box service, which still has available capacity without a service upgrade at that time. Of course, doing so with then mean that the critical date Date 2 for the Box must be reassessed, since the 1 GB/week average will have changed.
Other options identified are that additional service levels can be purchased (or removed) in order to maximize or minimize some particular variable or set of variables, including cost, speed, functionality, complexity, redundancy, uptime, etc. The SaaS Broker can accomodate business aspects such as contract durations, lead times, etc. in making its determinations. The set of options can then be presented on the SaaS Broker Console or some other form of output device so that a user can review it and make a decistion. Alternately, the system could be automated to make the decision on its own in order to maximize or minimize the variable or variable set noted above. Or, it could be manual up to some point, and then automated at some other. For example, if a resource is getting low, i.e., in a “yellow flag” area, the ultimate decision could be left to a user, whereas if the resource is in a critical state, i.e., in a “red flag” area, the automated SaaS Broker could make the decision.
The critical dates and critical states can also be determined based on business-related criteria. For example, if a contract having a one-year term expires in two weeks, the SaaS Broker to perform the same types of analyses as if a technical critical data was being approached and take the same types of responsive actions.
A similar procedure can be performed with respect to the Box service. The SaaS Broker in step S50, requests information about the storage space (or any other relevant property, parameter, or related measure) on the Box service. It then calculates S60 a difference value from the last time it made the request. Based on this information, and the delta time from the last request, the SaaS Broker can determine S70 a rate of change. Since the SaaS Broker has information related to the threshold of Box, e.g., its 20 GB threshold in the Box-Basic account, it can then determine a critical date at which time the Box-Basic account will be exhausted. Based on the information so obtained, the SaaS Broker can determine S80 what the next threshold or critical date is.
The SaaS Broker can thus determine the rate of change information S90 to reach the respective critical dates for the services, and notify the user S100 of any approaching thresholds in advance of them occurring.
In addition, the SaaS Broker can obtain information that is not necessarily directly related to the first service, but is usable with respect to other available (and possibly alternative) services. For example, even though the SaaS Broker knows that the Dropbox service criteria relates to a “number of documents” threshold, it can still make inquiries and calculations related to GB of storage space—it knows that this is not relevant for expanding or contracting the Dropbox service itself, but it also knows that other services that might become involved in the decision making and used as alternatives do take GB of storage space into account. Thus, the SaaS Broker's inquiry to Dropbox may include information about GB of storage (or any other relevant variable) and not just about the number of documents.
Similarly, the SaaS Broker's inquiry to Box may include information about number of documents, even though Box's threshold criteria relates to GB of storage, and not number of documents.
The above examples illustrate an embodiment related to disk storage capacity (in terms of GB or number of documents), but any measurable or determinable value can be taken into account, such as processing, storage, and network capacities. This provides a significant advantage to scalable systems/architectures.
In addition, as a part of the business restrictions taken into consideration, business factors/restrictions can also apply to the monitoring, i.e., there may be a cost for performing the monitoring (e.g., a cost for an API call to determine available storage space remaining). Thus, the cost of performing the monitoring itself can be varied depending on the criticality of the resource or a measure of variance associated with the monitored variable.
Weighting factors and other criteria could be used by the SaaS Broker to identify criteria that is more important. For example, it may be determined that a faster storage speed on Box is worth $1/GB/month more when deciding which server to use as the critical date approaches. Other criteria can be implemented as well—for example, the SaaS Broker could determine that 5% remaining capacity is the critical state, instead of 0%. In this way, the system can be extremely flexible in adapting to the changing need of users and modifiable based on the expandability of the cloud services.
The SaaS Broker can be designed to continually monitor the service usage and can alert either individual users or the company account administrators when service thresholds, a function of usage patterns, technical constraints, and business constraints are approaching. The SaaS broker can also suggest alternative service usage strategies since it is aware of the capabilities of all the services that a company is enrolled (e.g., Dropbox and Box).
