Mirantis, the pure play open source company, has announced the release of Mirantis OpenStack 9.0, which is based on OpenStack Mitaka.\n\u201cThe improvements in Mirantis OpenStack 9.0 are based on real-world production deployments of Mirantis OpenStack, including our collaborations with AT&T and Volkswagen,\u201d said Boris Renski, co-founder and CMO of Mirantis. \u201cThe improvements we made -- largely in the area of post-deployment operations -- integrate Mirantis\u2019 services expertise into the software so that we can deliver better business outcomes. Mirantis OpenStack 9.0 will be a valuable asset to Mirantis as we help customers build and operate private clouds.\u201d\nWhen I inquired about how the AT&T and Volkswagen deployment helped Mirantis and what improvements were made, Amara Kapadia, senior director, product marketing at Mirantis told me in an interview, \u201cWe implemented feedback from AT&T into improvements around lifecycle management; SDN & NFV features; multi-region support & high availability; and the overall stability of the release. Feedback from Volkswagen led to us making it easier to onboard workloads (such as CI\/CD pipeline, Kubernetes and multi-cloud support); security; and again, overall stability and manageability.\u201d\nTalking about the major improvements over the previous release of Mirantis OpenStack, and why customers should upgrade to 9.0, Kapadia said, \u201cBy upgrading to 9.0, customers will gain significant new functionality for Day-2 post-deployment management, new NFV features, improved stability and the Mitaka feature set.\u201d\nKapadia wrote in a blog post that they have added new functionalities in Mirantis OpenStack to simplify both initial deployment and post-deployment operations. Because no cloud is static and it changes after deployment they focused on the shaded box, i.e., post-deployment changes.\nCustomers can use Fuel, the OpenStack management project, to add certain plugins post deployment without having to redeploy the entire cloud. \u201cIt also keeps certain settings 'unlocked' after initial deployment. If a setting remains unlocked, it can similarly be changed without having to redeploy the cloud,\u201d wrote Kapadia.\nThis release also brings support for a wide range of network function virtualization (NFV) infrastructure acceleration features including huge pages, SR-IOV, NUMA\/CPU pinning and a technical preview of DPDK.\nOpenStack Mitaka is the 13th OpenStack release, and was built by a community of 2,336 developers and operators and users from 345 organizations. Mirantis dedicated 327 Mitaka committers, 87 core contributors, provided 1.37 million lines of code and conducted 52,000 reviews. Mirantis is not just one of the leading contributors to OpenStack, it is the top contributor to this release.
