Cloud computing is rapidly changing the Internet into a collection of clouds, which provide a variety of computing resources, storage resources, and, in the future, a variety of resources that are currently unimagined.
Yet, frequently it is difficult to effectively provide a given service from a single environment. This is so because a product or service offering often requires the cooperation of multiple services in providing functionality sufficient to be considered holistic.
Historically, service offerings deployed in an enterprise data center could be sufficiently controlled to ensure that trust relationships between the cooperating services were maintained. However, as seen in recent years, many service offering deployments grow to include multiple heterogeneous environments, which span multiple network segments, data center locations and/or include both data center (inside the firewall) and cloud (un-protected by firewall) environments. Such data center/cloud deployment environments are unsuitable for many service offerings; hampering the desired flexibility of the Information Technology (IT) department in providing low cost services to the enterprise.
That is, it is cost ineffective and impractical to think a given service can in all cases be wholly contained with all the supporting services it needs within a single cloud environment and yet the trend in the industry is to outsource services and data to cloud environments.
Various embodiments of the invention provide techniques for establishing a trusted cloud service. Specifically, and in one embodiment a method for deploying services to an ad hoc environment from a trusted environment where the ad hoc environment is un-trusted is presented.
An environment specification for a target environment is obtained that is un-trusted; the environment specification obtained within a trusted environment. Next, a package is created to include: certificates, a service image for a migrating service that is migrating to the target environment, a service identifier for the migrating service, and a package identifier for the package. Then, trust configuration information is established for the target environment having a trust configuration identifier. The trust configuration information is included in the package and the package is sent to a target service in the target environment for deployment of an instance of the migrating service, via the service image, within a created sub environment of the target environment that establishes trust with the trusted environment by processing components of the package.
A “resource” includes a user, service, system, device, directory, data store, groups of users, combinations and/or collections of these things, etc. A “principal” is a specific type of resource, such as an automated service or user that acquires an identity. A designation as to what is a resource and what is a principal can change depending upon the context of any given network transaction. Thus, if one resource attempts to access another resource, the actor of the transaction may be viewed as a principal.
An “identity” is something that is formulated from one or more identifiers and secrets that provide a statement of roles and/or permissions that the identity has in relation to resources. An “identifier” is information, which may be private and permits an identity to be formed, and some portions of an identifier may be public information, such as a user identifier, name, etc. Some examples of identifiers include social security number (SSN), user identifier and password pair, account number, retina scan, fingerprint, face scan, etc.
A “processing environment” defines a set of cooperating computing resources, such as machines (processor and memory-enabled devices), storage, software libraries, software systems, etc. that form a logical computing infrastructure. A “logical computing infrastructure” means that computing resources can be geographically distributed across a network, such as the Internet. So, one computing resource at network site X can be logically combined with another computing resource at network site Y to form a logical processing environment.
The phrases “processing environment,” “cloud processing environment,” and the term “cloud” may be used interchangeably and synonymously herein.
Moreover, it is noted that a “cloud” refers to a logical and/or physical processing environment as discussed above.
Various embodiments of this invention can be implemented in existing network architectures. For example, in some embodiments, the techniques presented herein are implemented in whole or in part in the Novell® operating system products, directory-based products, cloud-computing-based products, workload management products, and other products distributed by Novell, Inc.
Also, the techniques presented herein are implemented in machines, such as processor or processor-enabled devices. These machines are configured to specifically perform the processing of the methods and systems presented herein. Moreover, the methods and systems are implemented and reside within a non-transitory computer-readable storage media or machine-readable storage medium and are processed on the machines configured to perform the methods.
Of course, the embodiments of the invention can be implemented in a variety of architectural platforms, devices, operating and server systems, and/or applications. Any particular architectural layout or implementation presented herein is provided for purposes of illustration and comprehension only and is not intended to limit aspects of the invention.
As will be demonstrated in greater detail herein and below, the techniques provide mechanisms by which a service deployed in an ad hoc environment can initiate other services, where a trust relationship between the initiator and the service is established. The mechanisms can also be used to establish the secure communication channels in preparation for other trusted services to be deployed in the same ad hoc environment.
The embodiments are broken into three primary areas: 1: deploying to an ad hoc environment from a trusted environment where the ad hoc environment is un-trusted (
It is within this context that embodiments of the invention are now discussed within the context of the
The components of the
The embodiments herein proceed as follows where the Provider Trusted Environment 205 is deploying to an un-trusted Endpoint Environment 206.
Manage Endpoints 210 is used to maintain an Endpoint Specification 212, where the Endpoint Specification 212 specifies the information concerning the Endpoint Environment 206. The Manage Endpoints 210 then invokes Create Package 215.
Create Package 215 utilizes: the Endpoint Specification 212, the Public Certificates 216 of the Provider Trusted Environment 205, the Process Images 218, and the EPID 219, where the Public Certificates 216 contains the public key certificates used by the Provider Trusted Environment 205 to encrypt information that can only be decrypted by the associated private key owned by The Provider Trusted Environment 205, where the Process Images 218 contains the process images to be delivered to the Endpoint Environment 206, which will commence the establishment of a trusted environment and finish with a fully deployed trusted environment, where the Trust configuration 217 contains previously defined Trust Configuration information, which provides the Create Package 215 with information necessary to properly construct Package 221 and where the Trust Configuration 217 is annotated by the Create Package 215 concerning the FinalID 223 used to secure the new Endpoint Trusted Environment 247. In an embodiment, the Trust Configuration 217 is also annotated with the EPID (Ephemeral Package Identifier) 219 and ESID 219a (Ephemeral Service Identifier).
The final result of the Create Package 215 is the creation of the Package 221, which contains a package of information usable by the Endpoint Environment 206 to build the Endpoint Trusted Environment 247.
The Create Package 215 invokes Deliver Trust Boot 225, which consumes the information from the Endpoint Specification 212 to determine how to deliver the notification that the Package 221 is available. The Deliver Trust Boot 225 creates Trust Information 226, which contains the full information of the trust content to be delivered as the Trust Boot 225. The value of EPID 219, which is to be used to secure the Package 221 for the creation of the Endpoint Trusted Environment 247, is also contained within the notification to the Receive Trust Boot 230.
The Receive Trust Boot 230 receives the notification from the Trust Boot 225 along with the contents of the notification from the Trust Information 226 and invokes the Authorized Trust Boot 235. The Authorize Trust Boot 235 is a process, which requires a trusted authority to authorize the creation of the Endpoint Trusted Environment 247 and to specify the Environment Location 237. The Authorize Trust Boot 235 creates Trust Information 236 as a part of the authorization step and then invokes the Receive Package 240.
Part of the information delivered via the Deliver Trust Boot 225 to the Receive Trust Boot 230 is the location where the Receive Package 240 is to retrieve the Package 221 from the Provide Package 220 using the EPID 219 as proof of trust. In an embodiment, the Provide Package 220 receives the address of the Receive Package 240 from the Authorize Trust Boot 235 (dataflow not shown in the
At this point, a trusted authority has authorized the deployment of the Package 221 from the Provider Trusted Environment 205 into an environment specified in the Environment Location 237.
The Deployed Package 245 deploys the various processes contained in the Package 241 utilizing the information in the Trust Information 236 and the Environment Location 237 to begin creating the Endpoint Trusted Environment 247.
The beginning of the creation of the Endpoint Trusted Environment 247 is the deployment and instantiation by the Deployed Package 245 of the Set up Trust Environment 250 and the creation of the Configuration File 246. The Configuration File 246 contains information received from the Provider Trusted Environment 205 via either the Trust Information 226 or the Package 221.
The Setup Trust Environment 250 is a process instantiated within the Endpoint Trusted Environment 247, which was received by the Endpoint Environment 206 from the Provider Trusted Environment 205. Thus, the process has been retrieved from the Provider Trusted Environment 205. The Provider Trusted Environment 250 configures itself according to the information in the Configuration File 246 and instantiates another process provided by the Configuration File 245 called Gen Local Keys/Certs 255. The Gen Local Keys/Certs 255 constitutes the public and private keys and associated certificates used to establish the Endpoint Trusted Environment 247. It is critical that the keys and certificates in the Local Keys/Certs 256 be generated at the endpoint to provide both an Endpoint Trusted Environment 247 and to secure the information in the Endpoint Trusted Environment 247 even from the Provider Trusted Environment 205.
The Setup Trust Environment 250 now instantiates the Establish Trust 260 which, using the Configuration File 246, communicates with the Establish Trust 260 via an address provided by the Establish Trust 246 and proves that the environment being created at the Endpoint Trusted Environment 247 is authentic by establishing trust credentials using the ESID 219a, which was delivered as part of either the Receive Trust Boot 230 or the Package 241.
The Establish Trust 260 creates the Trust Definition 261 from the information delivered via the Receive Trust Boot 230 and the Package 241 and augments the Trust Definition 261 with information received from the Establish Trust 265 as a result of the successful trust establishment because of the utilization of the correct ESID 219a (Ephemeral Service Identifier) as well as receiving the FinalID 223, which becomes the permanent identifier for the trusted communication path between the Provider Trusted Environment 205 and the Endpoint Environment 206. Part of the establishment of this trust, is the delivery of the FinalID 223 from the Establish Trust 265 to the Establish Trust 260, which is key and certificate information used in communicating with the Provider Trusted Environment 205. The FinalID 223 is communicated to the Establish Trust 260 and saved in the Trust Definition 261 only if the correct information is exchanged between the Public Certificates 216 and the Establish Trust 265 utilizing either encryption and or digital signature technology, which uses the FinalID 223 and other certificates and/or keys as the active crypto material.
If the trust is established the Establish Trust 265 invokes the Production Images 270, which utilizes the Trust Information 226, the Endpoint Speciation 212, and process images in the Production Image Library 275 to provide the Production Processes 271. The Trust Definition 261 utilizes the Private Keys 272 or crypto material associated with the Private Keys 272 with the Public Certificates 216 as appropriate.
The end result is the secure and trusted transmission of the Production Processes 262, which is utilized by the Deployed Processes 280 together with the Trust Definition 261 and the Production Processes 262 to deploy the final Endpoint Trusted Environment 247 as shown by the cascaded process bubbles 285 in the
In an embodiment the Setup Trust Environment 250, the Deliver Trust Boot 225, the Configuration File 246, and the Establish Trust 260 are no longer used when the Endpoint Trusted Environment 247 is restarted or re-instantiated because the information has already been exchanged, trust established, and the appropriate key information provided.
The end result of the above invention mechanisms is the creation of the Endpoint Trusted Environment 247, where the processes within the environment 247 can be trusted by the Provider Trusted Environment 205 as can any traffic communicated between the production processes instantiated at 285 (identified in the
According to the
The process proceeds the same as discussed above with reference to the
In an embodiment the local keys and certificates are generated in the Endpoint Trusted Environment 306 via the Gen Local Keys/Certs 355 and stored in the Local Keys/Certs 356. In another embodiment, those keys are created in the Gen Local Keys/Certs 355a and stored the Local Keys/Certs 356a and are provided as part of the exchange between the Establish Trust 365 and the Establish Trust 360. These two embodiments are possible because the Provider Trusted Environment 305 and the Endpoint Trusted Environment 306 are already in a trusted environment and it is immaterial whether the local keys and certificates are generated in the Provider Trusted Environment 305 or the Endpoint Trusted Environment 306. In an embodiment, the customer of the cloud provider that will be using the Endpoint Trusted Environment 306 may want to be sure that the keys generated by Gen Local Keys/Certs 355 are generated in the environment where the trusted processing is taking place. Thus, there are two embodiments where keys and certificates can be generated either in the Provider Trusted Environment 305 or the Endpoint Trusted Environment 306.

Likewise, Cloud Services 420 and 425 (known to the prospecting service depicted in the
Cloud Measurement 430 analyzes the information in the Cloud Metrics 411 and 416, and the Service Metrics 421 and 426 to produce the Cloud Sites, Cloud Costs, Cloud Performance, and Cloud Reputation 435, which is aggregated information concerning Cloud Sites, Cloud Costs, Cloud Performance, and Cloud Reputation. In an embodiment, the Cloud Reputation 431 also provides information concerning cloud reputations as gathered the Cloud Reputation 431 from sources external to the embodiments discussed herein.
The Cloud Analysis 440 utilizes the information in Environment Requirements 441 to analyze the content of the Cloud Sites, Cloud Costs, Cloud Performance, and Cloud Reputation 435 in response to a query or interaction with Environment Management 445. The results of this analysis is the recommendation to the Environment Construction 450, which utilizes the Environment Requirements 441, the Environment Components 452 to create the Environment Packages 451, which are specific packages that can be used according to the
The Environment Deployment 445 utilizes the Environment Packages 451 to create the various Cloud Package 456 and 457 and then instantiates the Cloud Agents 460 and 465, which are specific agents that operate within the application programming interface of the Cloud Provider 470 and 475 to deploy the Cloud package 456 and 457. This is according to the discussion presented above with respect to the
In an embodiment the various certificates, keys, configurations, images, specifications and information may be stored in and provided by Configuration Management Database (CMDB), such as an Information Technology Infrastructure Library (ITIL) CMDB.
Some of the keys and certificates may be specified for signature only, while other keys and certificates are specified for encryption only. Moreover, utilization of asymmetric keys in conjunction with symmetric keys in order to encrypt information can be used. Embodiments herein utilize these technologies in ways that are appropriate.
