Abstract

A method, operable by a service registry in a service orientated architecture system, for providing a service within the system. A service request is received from a service requester in the system. The status of the service is checked as registered in the service registry. In response to the service not having a registered service endpoint or a property of the service falling below a defined threshold, a request is sent to service providers or subsequent service registries to provide a new service and according to the defined threshold. In response to a service provider providing the new service according to the defined standard, the service registry is updated with the new service and responding to the service requester that the service is available. The embodiments allow both direct interaction between the requester and provider or indirect interaction via a service management layer.

Claims

1. A method, operable by a service registry in a service oriented environment for provisioning a service within the environment, the method comprising:

receiving a request for a service from a service requester in the environment;

checking details of the requested service as registered in the service registry;

characterized by;

in response to the service requested not being registered, sending the request to one or more service providers to provide a new service; and

in response to a service provider providing the new service, updating, by a processor, the service registry with the new service and responding to the service requester that the service is available.

2. A method according to claim 1, wherein the service request includes a required standard of service and in response to the service being registered but not having the required standard, sending a request to one or more service providers to provide a service having the required standard;

and

in response to a service provider providing the service having the required standard, updating the service registry with the new service and standard of service.

3. A method according to claim 2, where the standard of service is a service property meeting a required threshold.

4. A method according to claim 3, wherein the service property is one or more of the following:

a rate of performing the service;

a cost of the service; and

a number of service instances provided.

5. A method according to claim 1 further comprising:

in response to the service requested not being registered, sending the service request to one or more subsequent service registries to provide a service provider for the service.

6. A method according to claim 5 further comprising:

sending located service information to the one or more subsequent service registries so that the one or more subsequent service registries can use previously located service information and subsequently locate service information to choose the service provider.

7. A method according to claim 1 further comprising:

mediating between the service requester and the service provider, wherein the service requester does not receive a service endpoint of the service provider but uses the service through a service management layer.

8. A method according to claim 7, wherein the service requester receives the service endpoint and requests the service directly from the service provider.

9. A method according to claim 1, wherein the service provider is provided as a virtual server.

10. A method according to claim 1, wherein the service is provided as a virtual application.
