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. Software distributions powered by OpenStack include Cloudscaling, Debian, Fedora, Piston Cloud Computing, Red Hat, SwiftStack, SUSE, Ubuntu and Stackops. To verify an OpenStack distribution, look for the logo on the right.

There are many service companies that bring OpenStack expertise to the table such as B1 Systems, Cloudscaling, CloudTP, Grid Dynamics, Metacloud, Mirantis and Rackspace. If you are looking for someone to guide you through these choices, help you execute your cloud strategy and provide support, this is a great place to start. Several of these companies such as Mirantis and Rackspace also provide OpenStack training courses for cloud administrators.
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 "Built for OpenStack" logo. Popular tools for managing OpenStack clouds include Enstratus, New Relic, Rightscale, Scalr and Zenoss.
