OpenStack was originally created by NASA and Rackspace to cater to their specific needs but it has since entered mainstream use. Linux has officially adopted it. OpenStack is an open source, cloud computing software system. It can be used for compute or object storage or a combination of both. It is a multi- project service for data centers. It offers multi use of services: It can be used as IAAS (Infrastructure as a Service), PAAS (Platform as a Service) or SAAS (System as Service).
OpenStack is rapidly gaining popularity and it is often dubbed the “Linux” of open source. OpenStack is seen as a cheaper alternative to Amazon’s AWS. Currently, it is used in 188 countries and has over 20 million lines of code. This is due to OpenStack being open source. This has created a global community of developers whose collaboration sustains OpenStack’s ecosystem. It is radically different as it offers users to deploy services that are hosted on the cloud servers rather than their end computers. This results in accelerated speed of the service. Furthermore, Open Stack simplifies scaling by giving each file a unique identifier. Consequently, Open Stack clouds are massively scalable. This enables the files to run simultaneously across multiple instances.
OpenStack has nine core components. These components are essential to deploy. The most integral component is the dashboard. The dashboard is for both users and administrators. Administrators can manage resources through the dashboard and users can access services through the web interface. Other core components are Nova, Neutron, Keystone, Cinder, Swift, Heat and Trove. These core components allow for functions such as creating instances, connectivity, building instances etc.
OpenStack supports the use of many different virtualization technologies. OpenStack is now used and supported by industry giants such as IBM and Linux. For businesses that IBM finds it particularly suitable because of its inter-operability. OpenStack can easily be customized to suit each client’s particular needs.
For businesses with security and regulatory concerns, a private cloud OpenStack is essential.The move towards private cloud is gaining traction; however, it’s not the decision to go for private cloud that is challenging, but also how to deploy it. There are several public cloud OpenStack providers but they are not the best option for those businesses with security or regulatory concerns. For these organizations, a private cloud OpenStack is the viable alternative.
