In this chapter, we have covered some of the basic networking principles that are used in today's modern data centers, with special focus on the AWS and OpenStack cloud technologies which are two of the most popular solutions.
Having read this chapter, you should now be familiar with the difference between Leaf-Spine and Spanning Tree network architectures, it should have demystified AWS networking, and you should now have a basic understanding of how private and public networks can be configured in OpenStack.
In the forthcoming chapters, we will build on these basic networking constructs and look at how they can be programmatically controlled using configuration management tools and used to automate network functions. But first, we will focus on some of the software-defined networking controllers that can be used to extend the capability of OpenStack even further than neutron in the private clouds and some of the feature sets and benefits they bring to ease the pain of managing network operations.
