OpenStack is an open-source cloud computing platform that provides infrastructure as a service. It was launched in 2010 by Rackspace Hosting and NASA to help organizations offer cloud services using standard hardware. OpenStack uses a set of software tools to build and manage cloud computing platforms. It controls large pools of computing, storage, and networking resources through a dashboard interface for administrators and users. Key components of OpenStack include Nova (manages virtual machines), Swift (object storage), Cinder (block storage), Neutron (networking), and Horizon (the dashboard interface).

*Introduction to Open Stack
What is Openstack? OpenStack is a free and open-source cloud computing software platform.Users primarily deploy it as an infrastructure as a service (IaaS) solution. OpenStack is a set of software tools for building and managing cloud computing platforms for public and private clouds. OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.
History * In July 2010, Rackspace Hosting and NASA jointly launched an open-source cloud-software initiative known as OpenStack. The OpenStack project intended to help organizations offer cloud-computing services running on standard hardware. * The OpenStack community collaborates around a six-month, time-based release cycle with frequent development milestones.During the planning phase of each release, the community gathers for the OpenStack Design Summit to facilitate developer working-sessions and to assemble plans.

Openstack Dashborad The OpenStack dashboard provides administrators and users a graphical interface to access, provision and automate cloud-based resources. The Dashboard is an extensible web app that allows cloud administrators and users to control their compute, storage and networking resources. As a cloud administrator, the dashboard provides an overall view of the size and state of your cloud. You can create users and projects, assign users to projects and set limits on the resources for those projects. The dashboard provides users a self-service portal to provision their own resources within the limits set by administrators. Refer Link : https://www.youtube.com/v/TgPTjrf1y0A?autoplay=1
What are the components of Openstack? Nova Swift Cinder Neutron Horizon Keystone Glance Ceilometer Heat
What is Nova ? Primary Component of Openstack which manages virtual machines.
What is Swift? Storage for Objects and Files. Objects will be videos, images, emails, backup and archives etc.
What is Cinder? Block storage for database.
What is Neutron? Provides networking capability for OpenStack. Manages all networking for virtual hosts.
About Components Nova is the primary computing engine behind OpenStack. It is a "fabric controller," which is used for deploying and managing large numbers of virtual machines and other instances to handle computing tasks. Swift is a storage system for objects and files. Rather than the traditional idea of a referring to files by their location on a disk drive, developers can instead refer to a unique identifier referring to the file or piece of information and let OpenStack decide where to store this information. This makes scaling easy, as developers dont have the worry about the capacity on a single system behind the software. It also allows the system, rather than the developer, to worry about how best to make sure that data is backed up in case of the failure of a machine or network connection. Cinder is a block storage component, which is more analogous to the traditional notion of a computer being able to access specific locations on a disk drive. This more traditional way of accessing files might be important in scenarios in which data access speed is the most important consideration. Neutron provides the networking capability for OpenStack. It helps to ensure that each of the components of an OpenStack deployment can communicate with one another quickly and efficiently.
Components Continue.. Horizon is the dashboard behind OpenStack. It is the only graphical interface to OpenStack, so for users wanting to give OpenStack a try, this may be the first component they actually see. Developers can access all of the components of OpenStack individually through an application programming interface (API), but the dashboard provides system administrators a look at what is going on in the cloud, and to manage it as needed.
