Policy engine for cloud platform
A policy engine is situated within the communications path of a cloud computing environment and a user of the cloud computing environment to comply with an organization's policies for deploying web applications in the cloud computing environment. The policy engine intercepts communications packets to the cloud computing environment from a user, such as a web application developer, for example, in preparation for deploying a web application in the cloud computing environment. The policy engine identifies commands corresponding to the communications packets and directs the communications packets to appropriate rules engines corresponding to such commands in order to execute rules to comply with an organization's policies. Upon completion of execution of the rules, the communications packets are forwarded to the cloud computing environment if they comply with the policies.
1. A system comprising one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to implement components comprising:
an application platform configured to execute on a plurality of first computers in a cloud computing environment, the application platform comprising a plurality of virtualized computing resources that are configured to host deployed applications,
wherein the application platform comprises a cloud controller that is configured to receive a plurality of commands to manage applications hosted on the application platform in the cloud computing environment; and
a policy engine comprising a plurality of rules engines, each rules engine corresponding to a respective command of the plurality of commands for the cloud controller of the application platform,
wherein the policy engine is configured to:
intercept a command issued to the cloud controller,
determine whether to permit or reject the intercepted command, according to one or more rules of the plurality of rules engines, the determining comprising:
directing the intercepted command to the corresponding rules engine of the plurality of rules engines,
applying, by the corresponding rules engine, one or more rules to the intercepted command, and
based on applying the one or more rules to the intercepted command, determining whether to permit or reject the intercepted command, and
in response to determining to permit the intercepted command, forward the intercepted command to the cloud controller.
2. The system of claim 1 , wherein the policy engine is further configured, if determining to reject the intercepted command, to send a notification of the rejection to an issuer of the intercepted command.
3. The system of claim 1 , wherein the policy engine is further configured to access a networked service before forwarding the intercepted command to the cloud controller.
4. The system of claim 1 , wherein the intercepted command is a cloud controller command for creating or managing an application on the application platform.
5. The system of claim 1 , wherein the policy engine is installed on a same computer system that issues commands to the cloud controller.
6. The system of claim 1 , wherein the policy engine is installed on the cloud computing environment.
7. A computer-implemented method comprising:
executing an application platform on a plurality of first computers in a cloud computing environment, the application platform comprising a plurality of virtualized computing resources that are configured to host deployed applications,
wherein the application platform comprises a cloud controller that is configured to receive a plurality of commands to manage applications hosted on the application platform in the cloud computing environment;
intercepting, by a policy engine installed on one or more second computers, a command issued to the cloud controller, the policy engine comprising a plurality of rules engines, each rules engine corresponding to a respective command of the plurality of commands for the cloud controller of the application platform;
determining, by the policy engine, whether to permit or reject the intercepted command, according to one or more rules of the plurality of rules engines, the determining comprising:
directing the intercepted command to the corresponding rules engine of the plurality of rules engines,
applying, by the corresponding rules engine, one or more rules to the intercepted command, and
based on applying the one or more rules to the intercepted command, determining whether to permit or reject the intercepted command; and
in response to determining to permit the intercepted command, forwarding, by the policy engine, the intercepted command to the cloud controller.
8. The method of claim 7 , further comprising:
if determining to reject the intercepted command, sending, by the policy engine, a notification of the rejection to an issuer of the intercepted command.
9. The method of claim 7 , further comprising:
accessing, by the policy engine, a networked service before forwarding the intercepted command to the cloud controller.
10. The method of claim 7 , wherein the intercepted command is a cloud controller command for creating or managing an application on the application platform.
11. The method of claim 7 , wherein the policy engine is installed on a same computer system that issues commands to the cloud controller.
12. The method of claim 7 , wherein the policy engine is installed on the cloud computing environment.
13. One or more non-transitory computer storage media encoded with computer program instructions that when executed by a plurality of computers cause the plurality of computers to perform operations comprising:
executing an application platform on a plurality of first computers in a cloud computing environment, the application platform comprising a plurality of virtualized computing resources that are configured to host deployed applications,
wherein the application platform comprises a cloud controller that is configured to receive a plurality of commands to manage applications hosted on the application platform in the cloud computing environment;
intercepting, by a policy engine installed on one or more second computers, a command issued to the cloud controller, the policy engine comprising a plurality of rules engines, each rules engine corresponding to a respective command of the plurality of commands for the cloud controller of the application platform;
determining, by the policy engine, whether to permit or reject the intercepted command, according to one or more rules of the plurality of rules engines, the determining comprising:
directing the intercepted command to the corresponding rules engine of the plurality of rules engines,
applying, by the corresponding rules engine, one or more rules to the intercepted command, and
based on applying the one or more rules to the intercepted command, determining whether to permit or reject the intercepted command; and
in response to determining to permit the intercepted command, forwarding, by the policy engine, the intercepted command to the cloud controller.
14. The non-transitory computer storage media of claim 13 , the operations further comprising:
if determining to reject the intercepted command, sending, by the policy engine, a notification of the rejection to an issuer of the intercepted command.
15. The non-transitory computer storage media of claim 13 , the operations further comprising:
accessing, by the policy engine, a networked service before forwarding the intercepted command to the cloud controller.
16. The non-transitory computer storage media of claim 13 , wherein the intercepted command is a cloud controller command for creating or managing an application on the application platform.
17. The non-transitory computer storage media of claim 13 , wherein the policy engine is installed on a same computer system that issues commands to the cloud controller.
18. The non-transitory computer storage media of claim 13 , wherein the policy engine is installed on the cloud computing environment.
