OpenNebula – Open source data center virtualization

Reaching for the Stars

Why OpenNebula?

OpenNebula is a powerful management and provisioning platform for the virtualized data center. Familiarizing yourself with the stack and the subsystems makes the cloud more tangible, and components that have been in use for years are treated to a whole new set of clothes under OpenNebula.

However, cloud computing does not necessarily mean outsourcing all services to third-party clouds; instead, it offers rich opportunities for your own operations. OpenNebula is gaining in popularity as an open source alternative to VMware [6]. The use of heterogeneous components and the high level of integration in particular characterize OpenNebula, helping it offer a comprehensive architectural approach, even for established IT infrastructures.
