Admission control based on the end-to-end availability

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, the process flow further identifying dependency in the process flow;
• executing the flow of transactions via the plurality of computer-implemented components identified in the process flow;
• monitoring the flow of transactions to detect a problem in the process flow and in at least one of the plurality of computer-implemented components via which the flow of transactions is executed, wherein transactions occurring between the computer-implemented components in the process flow are monitored, wherein a determination is made of whether the request can be completely processed without a problem in the process flow, the determination including at least determining whether a link in the dependency has a failure;
• responsive to determining the request can be completely processed without a problem in the process flow, allowing the request to proceed;
• and
• responsive to detecting a problem in the process flow, not allowing the request to proceed.

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 process flow further identifying dependency in the process flow,
• the hardware processor further operable to execute the flow of transactions via the plurality of computer-implemented components identified in the process flow,
• the hardware processor further operable to monitor the process flow of transactions to detect a problem in the process flow and in at least one of the plurality of computer-implemented components via which the flow of transactions is executed, wherein transactions occurring between the computer-implemented components in the process flow are monitored, wherein a determination is made of whether the request can be completely processed without a problem in the process flow, the determination including at least determining whether a link in the dependency has a failure,
• responsive to determining the request can be completely processed without a problem in the process flow, the hardware processor further operable to allow the request to proceed, and responsive to detecting a problem in the process flow, the hardware processor not allowing the request to proceed.
