Want a scalable Cloud? The word on everyone's lips in the IT Industry at the moment seems to be OpenStack. So lets take a few moments to digest what OpenStack is.
OpenStack is a global collaboration of developers and cloud computing techies, working together to produce the ubiquitious open source cloud computing platform for public and private clouds. The project was founded in 2010 via RackSpace and NASA, built with the purpose of assisting companies to run cloud computing services on standardised hardware. The project now has over 200 companies actively involved with it and has grown at a rapid rate over the past 3 years.
Built upon a modular architecture the latest OpenStack release, Havanna, currently compromises of the following nine components:
Horizon = Dashboard
Neutron = Networking
Neutron = Networking
Nova = Compute
Glance = Image Service
Swift = Object Storage
Cinder = Block Storage
Glance = Image Service
Swift = Object Storage
Cinder = Block Storage
Keystone = Identity Service
Ceilometer = Telemetry
Heat = Orchestration
Each of the nine components contain multiple modules and configuration files, these form the conceptual basis for your Cloud OS via the following relationships.
