OpenStack Consolidation Is (Almost) Complete-Cisco Buys PistonCloud, IBM Buys BlueBox

And there we go, two of the last men standing, finally falling. Today's news that IBM is acquiring OpenStack Blue Box supplier, while Cisco is buying Piston Cloud.

These deals come just weeks after another provider OpenStack, nebula, folded, and a few months after a major round of bidding in space with Cisco and EMC CloudScaling purchase Metacloud purchase. Alongside these deals, EMC also purchased HP bought Virtustream and Eucalyptus.
With these two agreements, we have almost reached the end of the long predicted consolidation OpenStack.

Mirantis, the high-flying seller OpenStack pure-play remains independent, and probably led to an IPO Meanwhile smaller players, such as the Australian Aptira respected provider continues to shine.
But the biggest names in US OpenStack vendors, this marks the end of pretty independent. So this little trip was a success or a failure?

It's a little hard to say because the terms of today`s not been announced, but most people suspect Piston Cloud approached the corporate death. That, coupled with the fact that Cisco already has a lot of things going on OpenStack indicate that, if the agreement was PistonCloud acquihire more than anything else. Cisco also announced last year over the delivery of Intercloud, a worldwide network of partners with OpenStack clouds driven engines.

Blue Box is perhaps a little more interesting. IBM, of course, buy SoftLayer a couple of years ago and also has its own history OpenStack happening. In recent Magic Quadrant for cloud providers, there was little love given the success of IBM in space, perhaps BlueBox will help with that.

When Blue Box sits in all this is a bit hard to say. Blue Box adds you an OpenStack offering managed remotely to the portfolio of IBM and, given the small amount of money the company had been raised to date, maybe the deal was a no-brainer for IBM (and allows the team Blue Box to get some breathing space).

Having seen OpenStack from day one, it's a little sad to see the end of all these independent companies - a certain vitality could only have gone now. But perhaps it is also a sign of a maturing project and a safe landing for everyone involved.
