Nova is the project name for OpenStack Compute

Nova is the project name for OpenStack Compute, a cloud computing fabric controller, the main part of an IaaS system. Individuals and organizations can use Nova to host and manage their own cloud computing systems. Nova originated as a project out of NASA Ames Research Laboratory.

  • Highly available: Scale to very serious workloads
  • Fault-Tolerant: Isolated processes avoid cascading failures
  • Recoverable: Failures should be easy to diagnose, debug, and rectify
  • Open Standards: Be a reference implementation for a community-driven api
  • API Compatibility: Nova strives to provide API-compatible with popular systems like Amazon EC2
