NASA Nebula Cloud Computing Platform
Nebula is an open-source cloud computing platform that was developed to provide an easily quantifiable and improved alternative to building additional expensive data centers and to provide an easier way for NASA scientists and researchers to share large, complex data sets with external partners and the public. Nebula is currently an Infrastructure-as-a-Service (IaaS) implementation that provides scalable compute and storage for science data and Web-based applications. Nebula IaaS allows customers to unilaterally provision, manage, and decommission computing capabilities (virtual machine instances, storage, etc.) on an as needed basis through a Web interface or a set of command-line tools.
