Usually, it would be another couple of months before the open-source OpenStack Foundation cloud released a new version of its cloud software. This time around the OpenStack community released the latest version, Ocata, on a one-time, shorter cycle. This release is focused on improving stability, scalability, and performance of the core compute and networking services.
The Ocata highlights include:
- New Nova compute “placement” application programming interface (API) that helps users intelligently allocate resources based on application needs. Cells v2 has also become the default to increase Nova scalability.
- OpenStack’s Horizon dashboard now supports keystone-to-keystone federation as new os-profiler UI, which gives operators the ability to detect performance issues across OpenStack services.
- Keystone federated identity now dynamically auto-provisions a project and assigns a federated user a role upon successful authentication.
- Ironic bare-metal service becomes more robust with networking and driver enhancements.
- Greatly improved performance and CPU usage for Telemetry projects: Storing millions of metrics per second is now possible using Ceilometer with Gnocchi storage engine.
- Active/Active HA in Cinder block storage service can now be implemented by drivers.
- Congress governance framework now has policy language enhancements to enable network address operations for better network and security governance.
Ocata also brings greater support for container-based application frameworks at the networking layer. In addition, with this release,…
