For NASA, Open-Source Cloud Computing Isn't Rocket Science

By Stephanie Overby , CIO |  Business, NASA

The Project: Develop the federal government's first open-source cloud-computing platform to provision high-performance computing, storage and network services for NASA's research community and enable scientists and engineers to share large, complex data sets with partners and the public.

The Business Case: Traditionally, it took several months and hundreds of man-hours to procure, configure and maintain new IT infrastructure for NASA scientists and engineers. Computing power dedicated to a single project or research area was underused, and energy costs were skyrocketing. IT leaders saw cloud computing as a potential solution to these technology challenges.

First Steps: NASA's cloud services project, nicknamed Nebula, was hatched two years ago. It transformed shipping containers into modular data centers, using virtualization to support up to 16 petabytes of data each and capable of halving energy use. For more than a year, Nebula was something "we were working on in the background," explains Ames Research Center CIO James Williams. For example, the Marshall Space Flight Center, another NASA agency, tested Nebula for predictive weather modeling, a project that would normally take a month to set up. Instead, Williams says, it was up and running in four days.

Nebula rocketed to the fore last fall, when federal CIO Vivek Kundra asked Ames to host USASpending.gov, a searchable database of federal funding. NASA launched an agencywide cloud computing initiative in April, and in July, Nebula's core software was chosen for OpenStack, an open-source initiative aimed at driving cloud-computing standards. OpenStack has hundreds of developers working on the code for any given project. "It could save taxpayers millions of dollars," says Williams.

Now users throughout NASA can unilaterally provision and manage IT resources for low-security applications on demand. Next year, IT will launch Nebula's platform as a service: a shared development framework, code repository and set of Web services that developers can use to deploy secure, policy-compliant software-as-a-service applications.

NASA has spent more than $10 million on the project, but it will be another year before the return is clear. "We want to get to a day where for every dollar you invest in this, you save six," says Adrian Gardner, CIO with Goddard Space Flight Center, a NASA division that provides staff and infrastructure for Nebula. "We're not looking to shift everything to the cloud. It's just another tool."
