Eucalyptus Systems takes public clouds private


By David Worthington
May 11, 2009 — 
A group of university researchers has invented a method for emulating cloud service APIs inside of private data centers, and it has formed a startup called Eucalyptus Systems to commercialize the technology.

When computer science researchers at the University of California, Santa Barbara needed to run a highly distributed scientific application on a grid of university sites, supercomputers and Amazon Web Services (AWS) all at the same time, they found that the task was impossible without developing new technology.

So in 2007, the researchers, led by Dr. Rich Wolski, began to build an open-source solution to emulate AWS in way that conformed to existing university infrastructure. It also could not be tied to any particular software or hardware environment, he said.

Client-side interface (via network)
The work was made possible by the openness of Amazon's APIs and the researchers' decision to be API-agnostic, added Wolski. "The [Amazon] APIs have changed four times since we started the project. Implementing each new edition was easier than the previous, so the architecture we designed seems to be right."

Amazon's API features are well documented due to its business relationships with co-providers such as CohesiveFT and RightScale, Wolski noted.

That research led to the formation of Eucalyptus Systems, a private company that is developing the technology for commercial use. The company received US$5.5 million first-round venture capital from Benchmark Capital and BV Capital on April 29, and Wolski is on indefinite leave from UC Santa Barbara.

Eucalyptus is focused on easing the installation, maintenance and support of its self-named open-source hybrid cloud platform, which combines public and private cloud resources. The platform enables organizations to gain the benefits of cloud computing without concerns of lock-in, security ambiguity and unexpected storage costs, Wolski said.

Eucalyptus uses an application packaging technology that impersonates the public cloud in a data center, he explained. It uses Web service protocols the company created to satisfy service requests, and it is now making them available as open source.

Future versions of the Eucalyptus cloud platform will modularize public cloud APIs into a region of a system to be replaced by and cohabitate with other APIs from other cloud providers, including Sun Microsystems, which Oracle is looking to purchase, he said.
