Abstract

A computer implemented method for creating a composite service. Dependencies are identified utilizing a set of active objects used to manage services to form identified dependencies in response to receiving a request for the composite service. The identified dependencies specify requirements of the composite service. The composite service has multiple components. Components are identified for the composite service using the identified dependencies to form identified components. The composite service is created using the identified components.

Claims

1. A computer implemented method for creating a composite service, the computer implemented method comprising:

responsive to receiving a service request notification instantiating a service component to process the service request notification;

identifying an active template to manage the instantiated service component, the active template comprising a plurality of active objects;

determining whether to instantiate a new active object in the identified active template to manage the instantiated service component; and

responsive to a positive determination to instantiate a new active object, generating the new active object, the new active object having a service state;

configuring the service state of the new active object to manage the instantiated service component in a desired state, the desired state being the service state required to achieve a desired behavior of the instantiated service component; and

sending a positive confirmation from the new active object, the positive confirmation being based on an availability of a requested service from the instantiated service component;

responsive to a negative determination to instantiate a new active object, reconfiguring a service state of an existing active object from a current state to a different desired state, the different desired state being the service state required to achieve a desired behavior of the instantiated service component.
