What is OpenStack?
OpenStack is a cloud operating system that controls large pools of
compute, storage, and networking resources throughout a datacenter, all
managed through a dashboard that gives administrators control while
empowering their users to provision resources through a web interface.
Marketing point of view
Devs' point of view
Really cool, open source, “Infrastructure as a
Service” (IaaS) provider.
