Emerging trends in OpenStack
One of the most interesting things about the way that OpenStack has evolved over its short history is the vast number of projects that have sprung up around the core set of compute, network, and storage services. As of the Newton release of OpenStack, there were almost sixty projects in the "Big Tent". These projects can be broadly lumped into two categories - those which automate additional infrastructure components and those which manage the installation, configuration, and life cycle of OpenStack itself. This first set of projects are typically patterned after analogues in Amazon Web Services and provide a fuller "stack" of services to be used in application deployments. The second set of projects contain configuration management code such as the Puppet modules we used in earlier chapters to deploy OpenStack and common services and libraries that are used by the other services.
