Forrest Research VP James Staten says he's not hugely surprised to see Microsoft's deliberate attempts to reintegrate Hyper-V support into OpenStack, as evident by the hiring of Pouliot. Microsoft's goal is to have broad-ranging support for its products and having Hyper-V support in OpenStack advances that goal. "While Microsoft has its own private cloud stack, they want Hyper-V, and Windows server for that matter, to be a ubiquitously available and thus supported as widely as possible," he says.
Similarly, OpenStack is looking to become a one-stop shop for IaaS cloud resources, so it's in the project's interest to include support for all major hypervisors. Overall though, Staten says Microsoft investing in OpenStack, even if it is a minimal amount, highlights the momentum of the OpenStack movement. "Clearly OpenStack has reached a level of momentum that Microsoft needs to show commitment to it."
