OpenStack is an Infrastructure as a Service (IaaS) cloud computing project started by Rackspace Cloud and NASA in 2010. Currently more than 150 companies have joined the project among which are AMD, Intel, Canonical, SUSE Linux, Red Hat, Cisco, Dell, HP, IBM and Yahoo!.[1][2][3][4] It is free open source software released under the terms of the Apache License.

OpenStack integrates code from NASA's Nebula platform as well as Rackspace's Cloud Files platform, and is included and released in both the Ubuntu [5] and Red Hat [6] Linux distributions.

History

NASA's Nebula Platform.

In July 2010, Rackspace Hosting and NASA jointly launched a new open source cloud initiative known as OpenStack. The mission of the OpenStack project is to enable any organization to create and offer cloud computing services running on standard hardware. The community's first official release, code-named Austin, was made available just 4 months later with plans to release regular updates of the software every few months.

OpenStack has a modular architecture that encompasses three components: [15]

  • Compute (Nova)
  • Object Storage (Swift)
  • Image Service (Glance)

Several components have been added for the next release: [8]

Compute (Nova)

OpenStack Compute (Nova) is a cloud computing fabric controller (the main part of an IaaS system). It is written in Python and utilizes many external libraries such as Eventlet (for concurrent programming), Kombu (for AMQP communication), and SQLAlchemy (for database access).

Object Storage (Swift)

OpenStack Object Storage (Swift) is a massively scalable redundant storage system.

In Aug 2009, Rackspace started the development of Swift, which is a complete replacement for the Cloud Files product. The initial development team consists of nine developers. [16]

Image Service (Glance)

OpenStack Image Service (Glance) provides discovery, registration, and delivery services for virtual disk images.

Amazon EC2 compatibility

OpenStack has APIs compatible with Amazon EC2 and Amazon S3 and thus client applications written for Amazon Web Services can be used with OpenStack with minimal porting effort.[17]
