Service Release focuses on the physical deployment of a service as well as defining the runtime attributes of the newly released service. From a deployment perspective, the process focuses on traditional configuration management issues as well as defining the a precise release unit.  

Once a unit is released, the logical policies must be created and deployed. This typically includes identifying runtime SLA's, security policies, etc. It is at this point where common mediations or service virtualizations are designed and deployed. 

Services will be deployed into various environments including development, staging and production. This same basic process holds true for each environment. 

Lastly, each time a service is moved into a new environment, the service must be re-tested to verify that the actual release process didn't break the service itself. Once a service has been verified full documentation of the service is performed. Metadata, policies and usage information is published to a service registry / repository.
