Ex-NASA CTO builds cloud dream team, launches Nebula

The cloud computing world has been anxious to hear former NASA CTO Chris Kemps plans since he left his post in the spring to pursue a startup venture, and on Wednesday morning he introduced his new company, Nebula. Its selling an OpenStack-based appliance for managing scale-out cloud deployments, and is backed by premier talent and investors.

Nebula isnt disclosing how much it has raised, but Co-founder and CEO Kemp said its tens of millions from seed investors Andy Bechtolsheim, David Cheriton and Ram Shriram Googles first three investors and venture firms Kleiner Perkins Caufield & Byers and Highland Capital Partners.

Kemps co-founders are Vice President of Engineering Devin Carlen, formerly CTO of Anso Labs, and Vice President of Business Development Steve OHara, formerly founder of Prime Networks, OnFiber and CoreLogic. Anso Labs is the IT contractor (acquired by Rackspacein February) that wrote the Nova code to power NASAs Nebula cloud, which now comprises the core compute component of OpenStack. Carlen was the first person to write code for Nova and led its development.

Nebula also employs a team of software and hardware architects with significant experience at Google, Amazon Web Services, Walt Disney and Microsoft. They arent just random people either, Kemp told me, theyve done really big things.

What theyre all working is fairly fascinating: A hardware appliance pre-loaded with customized OpenStack software and Arista networking tools, designed to manage racks of commodity servers as a private cloud. How commodity? Kemp said the first two certified reference architectu! res when the product is available in the fall will be for Dells PowerEdge C micro serversand Facebooks bare-bones Open Compute servers. In fact, Nebula rolled out its appliance at OSCON today in concert with Facebook and Rackspace.

Kemp wasnt planning to do an appliance, he admits, but initial investor Bechtolsheim convinced him it was the right approach. It lets Nebula provide a turnkey product for deploying OpenStack, Kemp explained, by optimizing and locking down some of the variables that might make deploying a private cloud more difficult. He likens it to the homogeneous approaches both Facebook and Google took to build out their infrastructures, or to that which Apple takes with its products: You specialize particular software to run on a particular hardware configuration and it just works.The hardware is a just an ideal delivery mechanism for the software.

But Nebula isnt just loading OpenStack onto an appliance, its also specializing the code to meet the needs of the enterprise clientele its seeking. That includes creating a petabyte-scale storage system complete with the types of enterprise features and support that customers would normally have to go to EMC, NetApp or another mega storage vendor to get. Some of the optimized code will go back into OpenStack, Kemp said, but some will remain within Nebula.

However, even with all the specialization, Nebula is very committed to building the core OpenStack code base. OpenStack exists because Eucalyptus didnt work at NASA, Kemp acknowledged, so he understands the importance of solid, customizable open source code.

Ultimately, he said, a b! etter Op enStack means a better Nebula because Nebula can focus on filling in the gaps and not on reinventing the wheel. Much like Bechtolsheim was successful at Sun Microsystems by building atop Unix and at Arista by using standard hardware components.

CTO Carlen is still heavily involved with the OpenStack Compute and dashboard teams, Kemp said, and Nebula will probably have more than 50 employees contributing to OpenStack once it begins hiring more.

Looking forward, Kemp sees an opportunity to have Nebulas appliance serve as the delivery model for an entire ecosystem of new software options. Companies pushing Hadoop-based products, NoSQL databases or other software that benefits from running in a scale-out infrastructure are potential partners, he said.

I dont want to sell against VMware, he explained, because theres a class of legacy applications with strict configuration requirements that need legacy software and hardware. But new applications are fair game.

Anyone following OpenStack knows that Nebula is hardly alone in selling products built atop the open source code, though. Kemp is adamant that Nebulas appliance approach is the right one for the OpenStack market, though, calling any companies focused on writing software great acquisition targets for large vendors that can port that software onto hardware platforms. At the time I spoke with Kemp, he thought Citrix, which has announced plans for a commercialized OpenStack distribution to complement the OpenStack-supporting Cloud.com software it just acquired, was in the best position to compete by offering an appliance.

Time will tell if Kemps assessment holds up and Nebulas business model really is what OpenStack users want. Yesterday, Dellannounced a reference architectu! re and s oftware designed to make OpenStack implementation and management a breeze. Theres also fellow startup Piston Cloud Computing, which recently raised $4.5 million to build a business around OpenStack. Joshua McKenty, Pistons CEO and co-founder, was the cloud architect of NASAs Nebula cloud infrastructure and holds an appointed seat on OpenStacks Policy Board.
