OpenStack is basically a set of software tools which are utilized for the building and the management of cloud computing platforms. The same may include public as well as private clouds. According to many individuals, OpenStack is essentially the future of cloud computing. Linux is distributed by many distributors, including Ret Hat Linux and OpenStack. A non – profit OpenStack Foundation is responsible for the management of the software and overseeing both the development and community building.
Introduction to OpenStack
OpenStack allows the users to handle various tasks for management of a cloud environment on the fly by deploying virtual machines and other instances. Horizontal scaling is made easier which simply stated, means that tasks which profit from running concurrently are allowed to serve less or more users easily, on the fly. All this needs is simply the spinning up of more instances. As an example – in case there's a mobile application which requires communication with the remote server might be able to divide tasks of communication with the users across varied instances, all communicating with each other, yet scaling easily as well as quickly with the gain of more users.
More important is the fact that it is open software. Anyone who wishes to access the source code can do so, make any desired modifications and also freely share the same with the community at large. Also, due to this, OpenStack gets the advantage of thousands of globally located developers who work in tandem with a common objective of developing the most robust, strongest and the most secure product that they possibly can.
What are the OpenStack Components?
Different moving parts make up the OpenStack. Also, any user can add additional components to cater to their requirements. There are 9 key components of the 'core' of this software.
- Nova – The primary engine for computing.
- Swift – Basic storage for all files and other objects.
- Cinder – It refers to the block storage component of OpenStack. It is analogous to the conventional idea of ability of the computer system to access specific locations on the disk drive.
- Neutron – This component of OpenStack is responsible for providing it with the capability of networking.
- Horizon – OpenStack graphical interface. It more or less can be referred to as the dashboard.
- Keystone – Identity service provider for Openstack. Essentially it refers to a central list of all the OpenStack cloud users which are mapped against their permitted services provided by the cloud.
- Ceilometer – The telemetry services are provided by the ceilometer.
- Glance –It is the image services provider.
- Heat – Orchestration component

Who can use OpenStack?
You may already be a user of OpenStack and yet be unaware of the fact! The sea (or rather the ocean) of applications which are run using OpenStack based backend seems to be ever - expanding with the growing number of companies which have begun adopting it as part of their cloud toolkit.
Access to all top distributors of Linux can be obtained at ItSpring Linux Academy. There is a lot of knowledge that can be gained. What we know can fit in small boats if compared to the vast ocean of knowledge. You may visit the website www.itsprings.com for further information and Linux Administration Training as well as Linux Fundamentals Training. It is the best place to enroll for Linux Course Online.
