Thomas Higdon from Akamai Technologies discusses how they use OpenNebula to clone virtual machine instances of Akamai's global content delivery network. This allows them to more quickly provision development and testing environments that mimic Akamai's production instances. OpenNebula manages the virtual machines and resources while an Akamai instance service exposes specific machine types and services. When changes need testing, they can clone an existing instance to a new environment rather than rebuilding it from scratch.
