In this chapter, you have learned about the life cycle of a service, and what types of changes in a service can lead to a new version of the service. You have seen that you need to communicate and keep track of the services and versions using a registry or repository. This tooling can be purchased or you can create the tools yourself. Finally, the attributes you need to store in the registry and the position of the registry/repository in your organization was discussed.
In the next chapter, you will learn about the governance processes that will keep your SOA under control.
