IBM Cloud Orchestrator, Version 2.5.0.4

Overview of OpenStack

IBM® Cloud Orchestrator works with the Kilo, Mitaka, and Ocata releases of OpenStack.

OpenStack is a collection of open source technologies that provide scalable computing software for both public and private clouds. For detailed information about OpenStack, see the OpenStack documentation and refer to the documentation of your OpenStack distribution.

You can choose between using IBM Cloud Manager with OpenStack or an OpenStack distribution of another vendor as underlying OpenStack infrastructure for IBM Cloud Orchestrator.

The versions prior to IBM Cloud Orchestrator V2.5.0.3 only support integration with OpenStack Kilo services configured on HTTP. For IBM Cloud Orchestrator V2.5.0.3, you can use OpenStack Mitaka with services that are configured on either HTTP or HTTPS. In IBM Cloud Orchestrator V2.5.0.4, you can use OpenStack Ocata with services that are configured on either HTTP or HTTPS. You can reconfigure an existing IBM Cloud Orchestrator to a new instance of OpenStack Mitaka / Ocata or install a new instance of both IBM Cloud Orchestrator and OpenStack Mitaka / Ocata. For more information about installing and configuring OpenStack Mitaka or Ocata, see Checking OpenStack prerequisites and Configuring OpenStack Mitaka and Ocata distribution.
