Systems and methods for policy-based application management
Systems and methods are provided for managing a plurality of applications comprising application instances running on a plurality of computer servers. A system for managing application includes an application scheduler. The application scheduler receives at least one policy for managing the applications over the computer servers. The application scheduler also receives usage information indicating performance of the applications and the computer servers. The application scheduler then applies the at least one policy to the usage information to determine whether policy violations exist. The application scheduler then determines and executes a modification action of the applications in response to the policy violation.
1. A method of managing a plurality of applications comprising application instances running on a plurality of computer servers, the method comprising:
receiving at least one policy for managing the applications over the computer servers;
receiving usage information indicating performance of the applications and the computer servers;
applying the at least one policy to the usage information to determine whether policy violations exist; and
determining and executing a modification action of the applications in response to the policy violation.
2. The method of claim 1 , wherein the modification action comprises activating an application instance on one of the computer servers.
3. The method of claim 1 , wherein the modification action comprises deactivating an application instance on one of the computer servers.

14. The method of claim 1 , wherein the at least one policy is based on a server class.
15. The method of claim 1 , further comprising generating and transmitting an instruction for the modification action.
16. A computer-accessible memory medium that store program instructions implementing an application scheduler, wherein the program instructions are executable by a processor to:
receive at least one policy for managing the applications over the computer servers;
receive resource usage information indicating performance of the computer servers;
receive user load information indicating usage by users of the applications;
compare the at least one policy with the resource usage information and the user load information to determine whether policy violations exist; and
determine and execute a modification action of the applications in response to the policy violation.
17. The memory medium of claim 16 , wherein the modification action comprises activating an application instance on one of the computer servers.
18. The memory medium of claim 16 , wherein the modification action comprises deactivating an application instance on one of the computer servers.
19. The memory medium of claim 16 , wherein the modification action comprises migrating an application instance between the computer servers.
20. The memory medium of claim 16 , wherein the usage information comprises processor usage.
21. The memory medium of claim 16 , wherein the usage information comprises memory usage.
22. The memory medium of claim 16 , wherein the usage information comprises a number of users.
23. The memory medium of claim 16 , wherein the usage information comprises application response time to user requests.
24. The memory medium of claim 16 , wherein the usage information comprises a number of connections to one of the applications.
25. The memory medium of claim 16 , wherein the at least one policy comprises enforcing a limit on processor usage.
26. The memory medium of claim 16 , wherein the at least one policy comprises enforcing a limit on memory usage.
27. The memory medium of claim 16 , wherein the at least one policy comprises enforcing a limit on connections to the applications.
28. The memory medium of claim 16 , wherein the at least one policy comprises enforcing a limit on users to the applications.
29. The memory medium of claim 16 , wherein the at least one policy is based on a server class.
30. The memory medium of claim 16 , wherein the program instructions are further executable to generate and transmit an instruction for the modification action.
31. A system for managing a plurality of applications running on a plurality of computer servers, the system comprising:
an application scheduler configured to receive at least one policy for managing the applications over the computer servers, receive resource usage information indicating performance of the computer servers, receive user load information indicating usage by users of the applications, compare the at least one policy with the resource usage information and the user load information to determine whether policy violations exist, and determine and execute a modification action of the applications in response to the existing policy violation; and
a resource controller configured to perform the modification action on the applications.
32. The system of claim 31 , wherein the modification action comprises activating an application instance on one of the computer servers.
33. The system of claim 31 , wherein the modification action comprises deactivating an application instance on one of the computer servers.
34. The system of claim 31 , wherein the modification action comprises migrating an application instance between the computer servers.
35. The system of claim 31 , wherein the usage information comprises processor usage.
