OpenStack Train Release Extends Security and Data Protection, Adds New AI and Machine Learning Support

20th release of OpenStack reflects operator priorities for ease of use, reliability and security.

The OpenStack community today released Train, the 20th version of the most widely deployed open source cloud infrastructure software.

Among the many enhancements provided in Train, three highlights are:

 

Enhanced security and data protection

  • Support for building software RAID: Ironic bare metal service protects services from disk failures. CERN already has this feature in production on 1,000 nodes.
  • Hardware-based encryption: Nova features a new framework supporting hardware-based encryption of guest memory to protect users against attackers or rogue administrators snooping on their workloads when using the libvirt compute driver. This feature is useful for multi-tenant environments and environments with publicly accessible hardware.
  • Data protection orchestration: Karbor adds events notifications for plan, checkpoint, restore, scheduled and trigger operations. This feature allows users to backup image boot servers with the new added data which is located on the root disk. Upstream development was led by China Mobile.

Increased Accelerator Support for AI/Machine Learning

  • Accelerator Lifecycle Management: In the Cyborg project, the Cyborg-Nova interaction spec creates a blueprint for launching and managing VMs with accelerators.

Improved resource management and tracking

  • The Train release completes the transition of the Placement capability into a standalone service, available independent of Nova. In Train, service response time is 0.7 seconds down from 16.9 seconds prior to the Stein release.
  • Nova features improvements to the scheduler to more intelligently filter results from the Placement service.
  • Watcher receives data from Placement, improving the Watcher compute data model.

Additional Highlights

Enhanced High Availability

Several Cinder drivers add support for new features like multi-attach and consistency groups.

Nova

Nova offers live migration support for servers with a NUMA topology, pinned CPUs and/or huge pages, when using the libvirt compute driver. Nova also delivers live migration support for servers with SR-IOV ports attached when using the libvirt compute driver. This enhancement, driven by the StarlingX project, enables a hypervisor to run both pinned and unpinned workloads in the same hypervisor.

Documentation

Improved documentation was a community-wide goal for the Train cycle in an effort to be a more accessible open source community. OpenStack operators can now access PDF-generated documentation by project.
