OpenStack community releases Ocata with focus on containers and stability at scale

The OpenStack Foundation has announced the release of Ocata, the 15th iteration of the open-source private cloud infrastructure platform.

The Foundation says that Ocata brings stabilisation to the core compute and networking services, plus better support for container-based application frameworks at the networking layer.

The development was cut from six to four months to accommodate a change in the usual release cycle of every six months.

In particular, Ocata sees more support for container applications and tools. Kolla for containerised OpenStack services, Kuryr for bridging container networking and storage, and Zun for container management were the projects with the most contributor growth. Magnum supports Mesosphere, and Kubernetes support now includes SUSE distribution.

The Foundation says that the roughly 2,000 developers who contributed to Ocata have “contributed significantly” to OpenStack’s stability, maturity and performance at scale. Release highlights include a new Nova compute API for the allocation of resources, and auto-provisioning for API client authentication service Keystone.


Operators will also be able to test their OpenStack deployments with a new Nova upgrade check to make sure they can upgrade in a stable way, and if not, what they’ll need to do before they can.

Critics had previously raised questions about how OpenStack could run alongside containers. But the Foundation made a point of demonstrating how VMs and containers could co-exist at the Summit in Austin, early in 2016.

The previous release, Newton, was seen as a leap in the development of the open source platform, capable of running VMs, containers, and bare metal all at scale.

And at the October 2016 summit in Barcelona, the OpenStack Foundation’s co-founder Jonathan Bryce was keen to highlight the role the platform could play within hybrid and multi-cloud environments.

“There is an incredible variety of workloads out there and for a lot of these users, they still use public cloud,” Bryce told ComputerworldUK at the time. “But people are getting more sophisticated in understanding that this is not the right time to use public cloud, this is the right time to use private cloud.”

Ocata will be on show at the OpenStack Summit in Boston this May, and will include speakers from Google, Harvard University, eBay, Bloomberg, and the US military.

It’s likely that the case studies on show will further hammer home the point the Foundation has been making over the last few years, that not only is OpenStack a good fit for the enterprise, but it is the de facto private cloud of choice for many large organisations and for a multitude of reasons.
