What is OpenStack?
Nowadays Openstack became a part of the cloud toolkit for many companies because of its trending features.
OpenStack is a cloud operating system that controls large pools of computing, storage, and networking resources throughout a data center, and are all managed through a dashboard that gives administrators control and providing their users to deploy resources through a web interface. It is a free and open-source platform and mostly deployed as an infrastructure-as-a-server(IaaS). It was created during the year 2010 and the latest release is the Ocata. OpenStack is a project consists of interconnected components with specific services like Dashboard, Compute, Networking, Object storage, Identity service, Image service, Telemetry, Orchestration.

Key Components of OpenStack
- HORIZONPurpose: Dashboard
A web-based management user interfaces like launching instances, managing networking and setting access controls.
- NOVAPurpose: Compute
A service that used to provision the Virtual machines on-demand and managed the machines on each node.
- NEUTRONPurpose: Networking
OpenStack interfaces are interconnected with this service. The users can create their own networks, control traffics and connects servers to other networks.
- SWIFTPurpose: Object storage
It allows users to store and retrieve files and objects. Swift architecture is distributed to allow horizontal scaling and to provide redundancy as failure-proofing.
- CINDERPurpose: Block storage
It manages storage volumes for virtual machines. This is a persistent block storage of instances running in nova.
- KEYSTONEPurpose: Identity management
A centralized identity service that provides authentication authorization for users.
- GLANCE:Purpose: Image service
Glance allows images(or virtual copies) of hard disks to be used as templates when deploying new virtual machines instances.
- CEILOMETERPurpose: Telemetry services
It provides billing services and usage reporting and metering about the users in the OpenStack.
- HEATPurpose: Orchestration component, It manages the infrastructure needed for a cloud service to run by allowing developers to store requirements of a cloud application in a file that defines what resources are necessary for that application.
