Methods and apparatus, including computer program products, are provided for executing a service using a set of software plug-ins. The method may include generating, at a first computer, a service request to execute the service. The method may also include processing, at a second computer, the generated service request using the set of software plug-ins associated with the service to create a modified service request by executing each of the software plug-ins in a sequence. Further, the method may include executing, at a third computer, the service using the modified service request and processing, by a second set of software plug-ins based on the sequence, a result from the executing step.
