OpenStack Cloud Computing Cookbook - Third Edition

Defining service endpoints

Each of the services in our cloud environment runs on a particular URL and port—these are the endpoint addresses for our services. When a client communicates with our OpenStack environment that runs the OpenStack Identity service, it is this service that returns the endpoint URLs that the user can use in an OpenStack environment. To enable this feature, we must define these endpoints. In a cloud environment, we can define multiple regions. Regions can be thought of as different datacenters, which would imply that they would have different URLs or IP addresses. Under the OpenStack Identity service, we can define these URL endpoints separately for each region. As we only have a single environment, we will reference this ...
