OpenStack is a free and open-source cloud operating system launched in 2010 which gives the user fine-grained control of computing resources. Virtual machines, network and storage settings can be managed through a browser based dashboard. For more information take a look at the OpenStack website.
Scalability – Easy scaling of virtual machines and distribution of data for efficient computations.
Configurability – OpenStack allows the configuration of any resource type available, such as virtual machines, network, block and object storage.
API Access – Any interaction with OpenStack can be automated via its API enabling users to script actions, e.g. starting and stopping of virtual machines.
