OpenStack backers have touted the interoperability and open source nature of the project as one of its chief benefits for not only service providers, but enterprise customers as well. Engates says having an open architecture allows customers to download the OpenStack code for free and deploy private clouds that mimic those from OpenStack providers, which could allow for easier creation of hybrid clouds. Having an ecosystem of OpenStack-based public clouds on the market gives customers choice to be able to move cloud services among various providers.
Rackspace and HP are the first major providers to have public cloud offerings based on OpenStack. Internap, another IaaS provider, has an OpenStack-supported offering, but it is on a smaller scale.
OpenStack is still far from being a "turnkey" solution for enterprises at this point, says Gartner's Leong. She sees raw OpenStack code being more widely used by service providers than enterprises, but does also see plenty of room for companies such as Piston Cloud Computing that will take the OpenStack code and create business offerings.
Joshua McKenty, president and CEO of Piston, and one of the co-founders of the OpenStack project from his time at NASA, says he's happy to see the advancements from Rackspace and HP, but he questions if the moves could have been made earlier. "It's about time," he says, noting that Rackspace has been working on implementing the OpenStack code since the project was founded. Engates admits that he "probably would have liked it to have gone a little faster," but he notes that the company wanted to make sure the offering was ready for consumers and had been tested appropriately. Plus, in addition to integrating the OpenStack compute platform into the company's storage services, Rackspace has spent the past few years building up the OpenStack community, which now includes more than 180 companies and 3,300 developers. Since then, however, the project has seen increased competition, particularly from Citrix, which created its own open source project named CloudStack after it defected from OpenStack. Open soruce project Eucalyptus is another competitor.
