This document provides an introduction to OpenStack, an open-source cloud operating system. It begins by defining OpenStack as a set of tools for building public or private clouds, then describes its key components like compute, storage, networking, and identity services. The document compares OpenStack to AWS, noting similarities and differences in their virtual machine, storage, networking, security, and orchestration services. It also outlines when OpenStack may be better suited than AWS, such as for organizations with specific hardware requirements. Finally, it briefly introduces DevOps tools like Chef, Puppet, and Ansible that can be used to automate operations on OpenStack clouds.

What is OpenStack?
Simply put, OpenStack is a set of software tools for
building and managing cloud computing platforms for
both public and private clouds.
Backed by some of the biggest organizations in software
development and hosting, as well as thousands of
community members, OpenStack is all set to redefine the
future of cloud computing.

What is OpenStack?
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.

So what next after OpenStack
After setting up the OpenStack environment, we can perform DevOps techniques on top of it.
These DevOps techniques are performed with the help of a few dedicated Orchestration tools.
Some of those tools are:
Chef
Puppet
SaltStack
Ansible
Docker
Git
SVN etc.
