Abstract

The method includes receiving a request to access an application. The method further includes identifying features of the application comprising one or both of an application dependency framework, and an application context root. The method further includes determining if a first cluster member is available to process the request for access to the application based at least in part on one or more of the identified feature of the application, a load on the first cluster member, and a resource utilization on the first cluster member. The method further includes, in response to determining that the first cluster member is not available, sending a request to enable an execution environment associated with the first cluster member, based upon the identified feature of the application.

Claims

1. A method for enabling and disabling execution environments, the method comprising:

receiving, by one or more computer processors, a request to access an application;

identifying, by one or more computer processors, features of the application comprising one or both of an application dependency framework, and an application context root;

determining, by one or more computer processors, if a first cluster member is available to process the request for access to the application based at least in part on one or more of the identified features of the application, a load on the first cluster member, and a resource utilization on the first cluster member; and

in response to determining that the first cluster member is not available, sending, by one or more computer processors, a request to enable an execution environment associated with the first cluster member, based upon the identified features of the application.

2. The method of claim 1, further comprising:

determining, by one or more computer processors, whether an enabled execution environment is being utilized; and

responsive to determining that the enabled execution environment is not being utilized, sending, by one or more computer processors, a request to disable the enabled execution environment.

3. The method of claim 1, wherein determining if a first cluster member is available to process the request for access to the application based at least in part on one or more of the identified features of the application, a load on the first cluster member, and a resource utilization on the first cluster member comprises:

determining, by one or more computer processors, that no cluster member is available to process the request for access to an application;

identifying, by one or more computer processors, a second cluster member which has a disabled execution environment; and

determining, by one or more computer processors, if the identified second cluster member can process the request for access to the application if the disabled execution environment becomes enabled based at least in part on one or more of the identified features of the application, a load on the second cluster member, and a resource utilization on the second cluster member.

4. The method of claim 3, further comprising:

responsive to determining the identified second cluster member cannot process the request for access to the application if the disabled execution environment becomes enabled, creating, by one or more processors, a new cluster member, wherein the new cluster member comprises the application and one or more enabled execution environments associated with the application.

5. The method of claim 1, wherein sending a request to enable an execution environment based upon the identified features of the application comprises:

identifying, by one or more computer processors, a computer language needed for the application; and

sending, by one or more computer processors, a request to enable the execution environment based at least in part upon the identified computer language.

6. The method of claim 1, wherein identifying an application dependency framework comprises identifying, by one or more computer processors, information indicating the application may require another application on the same cluster member.

7. The method of claim 1, wherein identifying an application context root comprises identifying, by one or more computer processors, data indicating a unique application which is to be invoked on the first cluster member.

8. A computer program product for enabling and disabling execution environments, the computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising;

program instructions to receive a request to access an application;

program instructions to identify features of the application comprising one or both of an application dependency framework, and an application context root;

program instructions to determine if a first cluster member is available to process the request for access to the application based at least in part on one or more of the identified features of the application, a load on the first cluster member, and a resource utilization on the first cluster member; and

in response to determining that the first cluster member is not available, program instructions to send a request to enable an execution environment associated with the first cluster member, based upon the identified features of the application.

9. The computer program product of claim 8, further comprising program instructions to:

determine whether an enabled execution environment is being utilized; and

responsive to determining that the enabled execution environment is not being utilized, program instructions to send a request to disable the enabled execution environment.

10. The computer program product of claim 8, wherein determining if a first cluster member is available to process the request for access to the application based at least in part on one or more of the identified features of the application, a load on the first cluster member, and a resource utilization on the first cluster member comprises program instructions to:

determine that no cluster member is available to process the request for access to an application;

identify a second cluster member which has a disabled execution environment; and

determine if the identified second cluster member can process the request for access to the application if the disabled execution environment becomes enabled based at least in part on one or more of the identified features of the application, a load on the second cluster member, and a resource utilization on the second cluster member.

11. The computer program product of claim 10, further comprising program instructions to:

responsive to program instructions to determine the identified second cluster member cannot process the request for access to the application if the disabled execution environment becomes enabled, program instructions to create a new cluster member, wherein the new cluster member comprises the application and one or more enabled execution environments associated with the application.

12. The computer program product of claim 8, wherein sending a request to enable an execution environment based upon the identified features of the application comprises program instructions to:

identify a computer language needed for the application; and

send a request to enable the execution environment based at least in part upon the identified computer language.

13. The computer program product of claim 8, wherein the program instructions to identify an application dependency framework comprise program instructions to identify information indicating the application may require another application on the same cluster member.

14. The computer program product of claim 8, wherein program instructions to identify an application context root comprises program instructions to identify data indicating a unique application which is to be invoked on the first cluster member.

15. A computer system for enabling and disabling execution environments, the computer program system comprising:

one or more computer processors;

one or more computer readable storage media;
