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.”

API-driven, self-service Software Defined Datacenter

What is Openstack

Full Havana installation = 32 services

What is Openstack

Openstack principles:

Open community and documentation
