With some technical skills, DevStack is a great option to install and run an OpenStack cloud on your laptop (or even inside the VM on a cloud). DevStack is ideal for potential users who want to see what the Dashboard looks like from an admin or user perspective, and OpenStack contributors wanting to test against a complete local environment.

Several members of the community came together to produce the "OpenStack Operations Guide", now available electronically and in print. A portion of the proceeds benefit the OpenStack Foundation.
When choosing an open source cloud operating system, a vibrant commercial ecosystem is key to the long term viability of your platform choice. With OpenStack, there are over 180 participating companies and we encourage you to dig in and find the right path for you.
To start, there are many ways to install and deploy OpenStack through software distributions, each of which add their own value to the cloud operating system. The OpenStack Marketplace includes a list of commercial software distributions powered by OpenStack. In addition to commercial offerings, OpenStack is also included with several non commercial linux distributions including Debian and Fedora.

There are many service companies that bring OpenStack expertise to the table. If you are looking for someone to guide you through these choices, help you execute your cloud strategy, provide support or training, the OpenStack Marketplace is a great place to start.
Most users get started by selecting a distribution from the Marketplace or by picking one of the options listed under "Install OpenStack" from the official documentation, but if you're interested in going straight to the source for each component, you can also download the source code. If you're a developer, also be sure to learn how to contribute.
Once you have your OpenStack cloud up and running, you'll want to explore the many tools available to help you manage it. These are tools that talk to the OpenStack API and can be found by looking for the "OpenStack Compatible" logo.
