Summary
This chapter was a description of how to have an open source cloud-computing solution within a small or large computer infrastructure. We started by defining the concept of cloud computing, and then we introduced OpenStack and described its components in brief. We showed a practical way to set up and configure an OpenStack node using—by choice—all of its components.
In the next chapter, you are going to learn automatic system configuration using one of the most recent tools that does this in a well-organized way—Puppet.
