Suse and Mirantis, key backers of the OpenStack cloud computing framework, have released new versions of their enterprise-grade distributions based on Liberty, the most recent update of OpenStack.
Suse is touting high availability and non-disruptive upgrades as part of the build, while Mirantis is focusing on stability for customers.
OpenStack Liberty, the 12th release of the open source cloud computing project, was released by the OpenStack community in October, but it has taken time for firms offering enterprise-grade services and support based on OpenStack to incorporate the changes into their own offerings.
Suse OpenStack Cloud 6 is available now and integrates the cloud platform with the Suse Linux Enterprise Server 12 SP1 operating system and the Suse Enterprise Storage software-defined storage platform based on the Ceph project.
The new release delivers high availability enhancements, plus support for non-disruptive upgrades for future releases, Suse said. It also brings better Docker and IBM z Systems mainframe support to make it easier to move business-critical applications and data to the cloud.
The IBM support refers to the z/VM hypervisor, which Suse OpenStack Cloud 6 can now support alongside Xen, KVM, Hyper-V and VMware, allowing customers to incorporate mainframe resources into an OpenStack private cloud.
Docker containers support comes via Suse Linux Enterprise 12 SP1, which added this capability in January, while OpenStack Cloud 6 also now has full support for the OpenStack Manila project, which adds a file-based storage service to complement the Swift and Cinder projects for object and block storage.
Suse now offers training and certification for IT professionals focused on the deployment and operation of OpenStack private clouds to better meet the requirements of enterprise customers.
"The market has started to realise that do-it-yourself approaches to deploying private clouds are too time consuming, too expensive and too prone to failure. As the first to offer an enterprise OpenStack cloud distribution, Suse continues to focus on providing the OpenStack solution of choice for businesses," said chief executive Nils Brauckmann.
Meanwhile, Mirantis styles itself as the "pure play" OpenStack provider, as it does not tie its distribution to a build of Linux and leaves the choice of operating system to customers.
The firm has incorporated customer feedback into Mirantis OpenStack 8.0 from thousands of the largest OpenStack users around the globe, who listed stability as their top priority.
"To that end, with the 8.0 release we have introduced a brand new performance test suite. This measures the performance of components such as networking, storage I/O and Ceph, and has helped fix a new class of bug, for example a race condition during create and delete operations of Cinder volumes," said Mirantis director of solutions marketing Amar Kapadia.
For developers, the latest release also adds support for OpenStack's Ironic bare metal provisioning tool, plus additional Murano and Kubernetes capabilities for containers.
"Up until the OpenStack Liberty release, we haven't felt that Ironic was hardened enough to be put into production, but now it is and we've integrated Fuel and Ironic so that Ironic can be deployed with the same simplicity as other OpenStack services," said Kapadia.
On the container side, this release adds the ability to scale automatically in response to the load generated by the Kubernetes orchestration platform through a new Kubernetes Murano package. This also enables workloads to burst to Google Cloud if local OpenStack resources run out, according to the firm.
Mirantis OpenStack 8.0 is available to download now as a single commercially supported package in ISO or IMG format. Documentation and knowledge base access is available to customers with a support subscription.
