Abstract

Providing admission control for a request may comprise creating a process flow associated with the request, the process flow identifying a plurality of computer-implemented components and a flow of transactions occurring between the computer-implemented components; executing the flow of transactions on the plurality of computer-implemented components; logging the flow of transactions; monitoring the flow of transactions to detect a problem in the flow or one or more of the components, or combination thereof; responsive to not detecting a problem in the flow or one or more of the components, or combination thereof, allowing the request to proceed; and responsive to detecting a problem in the flow or one or more of the components, or combination thereof, not allowing the request to proceed.

Claims

1. A method for providing admission control associated with a request in a computer system, comprising:

creating, by a processor, a process flow associated with the request, the process flow identifying a plurality of computer-implemented components and a flow of transactions occurring between the computer-implemented components;

executing the flow of transactions via the plurality of computer-implemented components;

logging the flow of transactions;

monitoring the flow of transactions to detect a problem in the flow or one or more of the components, or combination thereof;

responsive to not detecting a problem in the flow or one or more of the components, or combination thereof, allowing the request to proceed; and

responsive to detecting a problem in the flow or one or more of the components, or combination thereof, not allowing the request to proceed.

2. The method of claim 1, wherein the process flow is created based on a knowledge base that stores a topology associated with the request, a process pattern associated with the request, and configuration of the plurality of computer-implemented components.

3. The method of claim 2, wherein the knowledge base stores multiple topologies and multiple process patterns, wherein a topology corresponds to a class of requests and a process pattern corresponds to the class of requests.

4. The method of claim 1, further comprising updating the process flow based on the logging of the flow of transactions.

5. The method of claim 1, further comprising taking a corrective action based on one or more policies and environmental changes responsive to detecting a problem in the flow or one or more of the components, or combination thereof.

6. The method of claim 1, wherein the request comprises one or more of a request to provision a virtual or physical machine in a cloud environment, or an action that involves processing of automated transaction on the server comprising one or more of adding memory, adding a central processing unit, adding a disk, and applying patching.

7. The method of claim 1, wherein the method is performed periodically.

8. A computer readable storage medium storing a program of instructions executable by a machine to perform a method of providing admission control associated with a request in a computer system, the method comprising:

creating a process flow associated with the request, the process flow identifying a plurality of computer-implemented components and a flow of transactions occurring between the computer-implemented components;

executing the flow of transactions via the plurality of computer-implemented components;

logging the flow of transactions;

monitoring the flow of transactions to detect a problem in the flow or one or more of the components, or combination thereof;

responsive to not detecting a problem in the flow or one or more of the components, or combination thereof, allowing the request to proceed; and

responsive to detecting a problem in the flow or one or more of the components, or combination thereof, not allowing the request to proceed.

9. The computer readable storage medium of claim 8,

wherein the process flow is created based on a knowledge base that stores a topology associated with the request, a process pattern associated with the request, and configuration of the plurality of computer-implemented components.

10. The computer readable storage medium of claim 9, wherein the knowledge base stores multiple topologies and multiple process patterns, wherein a topology corresponds to a class of requests and a process pattern corresponds to the class of requests.

11. The computer readable storage medium of claim 8, further comprising updating the process flow based on the logging of the flow of transactions.

12. The computer readable storage medium of claim 8, further comprising taking a corrective action based on one or more policies and environmental changes responsive to detecting a problem in the flow or one or more of the components, or combination thereof.

13. The computer readable storage medium of claim 8, wherein the request comprises one or more of a request to provision a virtual or physical machine in a cloud environment, or an action involving processing of automated transaction on a server comprising adding memory, adding a central processing unit, adding a disk, and applying patching.

14. The computer readable storage medium of claim 8, wherein the method is performed periodically.

15. A system for providing admission control associated with a request in a computer system, comprising:

a hardware processor;

a storage device storing a plurality of topologies associated with a plurality of requests respectively, a plurality of process patterns associated with the plurality of requests respectively, and configurations of computer-implemented components,

the hardware processor operable to create a process flow associated with the request, the process flow identifying a plurality of the computer-implemented components and a flow of transactions occurring between the computer-implemented components in fulfilling the request based on the topology associated with the request and the process pattern associated with the request,

the hardware processor further operable to execute the flow of transactions via the plurality of computer-implemented components,

the hardware processor further operable to log the flow of transactions,

16. The system of claim 15, wherein the hardware processor further updates the process flow based on the logging of the flow of transactions.

17. The system of claim 15, wherein the hardware processor is further operable to take a corrective action based on one or more policies and environmental changes responsive to detecting a problem in the flow or one or more of the components, or combination thereof.

18. The system of claim 15, wherein the request comprises one or more of a request to provision a virtual or physical machine in a cloud environment, or an action that involves processing of automated transaction on a server comprising adding memory, adding a central processing unit, adding a disk, and applying patching.
