Pivotal and Mirantis recently announced a partnership whereby Pivotal will support deployments of Pivotal Cloud Foundry on the Mirantis OpenStack platform. Meanwhile, Mirantis will resell Pivotal Cloud Foundry to its IaaS customers. The partnership between Pivotal and Mirantis reinforces the integration between OpenStack and Cloud Foundry by bringing together two leading open source technologies in the cloud computing space and delivering a full stack marked by infrastructure provisioning and management capabilities in addition to agile application development functionality. As noted in a Pivotal blog post, customers can deploy Pivotal Cloud Foundry on Mirantis OpenStack by following a runbook that streamlines its deployment. The collaboration between Pivotal and Cloud Foundry underscores the ascendancy of open source cloud computing technologies that are predicated upon transparent governance frameworks and the contributions of developers and organizations from all over the world. By offering Pivotal Cloud Foundry on top of Mirantis OpenStack, Pivotal and Mirantis render available an on demand solution that absolves companies of the hassle of integrating an application development platform into an infrastructure deployment. The partnership gives Mirantis the feather in its cap constituted by an enterprise-grade PaaS in the form of Pivotal Cloud Foundry. Correspondingly, Pivotal benefits from the increased sales channel exposure enabled by access to Mirantis customers. The real winner from this partnership, however, is OpenStack insofar as it continues to cement its reputation for having the ability to integrate with major PaaS, database and Big Data technologies as recently exemplified by the agreement between Oracle regarding its Database as a Service and Mirantis, and Piston Cloud’s announcement of Piston OS 4.0.
