Connecting to OpenStack and OpenStack-based clouds

There are two ways to connect to an OpenStack cloud or a cloud that is based on OpenStack, such as IBM® Cloud Orchestrator. Which method you choose depends on whether you want to use user accounts from an LDAP server or from an OpenStack Keystone server.

The following diagrams show summaries of these two methods of connecting to OpenStack-based clouds.

In the first diagram, the blueprint design server retrieves account information from an LDAP server and authentication information from the Keystone identity service. A topology that includes the blueprint design server, an OpenStack-based cloud, an OpenStack Heat engine, a Keystone server, and an LDAP server

In the second diagram, the blueprint design server retrieves both account and authentication information from the Keystone identity service. A topology that includes the blueprint design server, an OpenStack-based cloud, an OpenStack Heat engine, and a Keystone server
