Scaling Your Infrastructure

In this chapter, we are going to analyze all the technologies used to deploy a complete web application in Amazon Web Services (AWS). In particular, we will look at how to create a monolithic application in one single machine and decompose the application into multiple pieces in order to achieve scalability and reliability. 

Every section of this chapter first has a theoretical part that focuses on the overarching idea as well as the AWS technologies necessary to implement it. It also has a practical example, which makes it possible to put what is explained into action. 

Starting with the monolith approach to all the software on a single machine, we are going to see when and why it is convenient to break it into multiple pieces to achieve better scalability and reliability. To do this, moving the data (also called the state...
