Openstack Endpoints
The process of engaging an OpenStack cloud is started through the querying of an API endpoint. 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, this service returns the endpoint URLs that the user can use in an OpenStack environment. Following the endpoints of our cloud:
