Pushed by the recent buzz, I just started learning around OpenStack.
This video has simple and good introductory explanation. There’re many different hypervisors which provides virtual machines, and it’s getting difficult to manage them as it grows. OpenStack Shared Services are located on top of hypervisors and provides unified management interfaces.
Nice keynote to demonstrate how OpenStack can work in production. The infrastructure can grow without service interruptions. Canonical and Ubuntu seems gaining presence on these cloud-based solutions.
The keynote from the Rackspace. The [OpenStack Code Commits] graph (at around 7:10) is interesting, which indicates a variety of companies are taking initiative.
