Introduction

What is OpenStack?

Software

OpenStack is a software package that provides a cloud platform for Public and Private cloud covering various use cases including Enterprise and Telecom. The main focus is on Infrastructure as a Service (IaaS) cloud and additional services built upon IaaS. The Technical Committee maintains an evolving vision for OpenStack clouds describing the overall design scope for an OpenStack cloud and the principles of cloud platforms in general, and OpenStack in particular, that each service within OpenStack is expected to follow.

As a software, OpenStack is built from a set of microservices which can be combined into different setups based on the actual need. The services provide REST APIs for their users. These can be the cloud operators or other services. To make the usage of the APIs easier it is possible to use Software Development Kits (SDKs) which are also developed as projects inside the OpenStack community.

Documentation is very important for the community so you can find guidelines about how to install and use the services developed by the project teams on the documentation website for OpenStack.

The services developed by the community are available as tarballs to install them from source and are also picked up and packaged to make it available for different Linux distributions or as part of OpenStack distributions.

Community

OpenStack is a community working towards one mission:

To produce a ubiquitous Open Source Cloud Computing platform that is easy to use, simple to implement, interoperable between deployments, works well at all scales, and meets the needs of users and operators of both public and private clouds.

OpenStack provides an ecosystem for collaboration. It has infrastructure for

  • Code review

  • Testing

  • CI

  • Version control

  • Documentation

  • a set of collaboration tools, like a wiki, IRC chanels, Etherpad and Ethercalc.

The four opens

The basic princinples of the OpenStack community are the four opens.

Groups

There are lots of people working on OpenStack organized into different groups. These are described in the Special Interest Groups section of the Governance chapter.

What is a contribution?

In open source projects a contribution can be anything which helps the project to accomplish its mission. In addition to code contribution it can be testing, documentation, requirements gathering, bug reporting and so forth.
