Chapter 2: Understanding Database Fundamentals

Before we start looking at specific AWS database technologies and services, it's important to understand the different types of databases that are available and what type of workloads you should consider putting into each database. We are doing this so that when we start learning about the various AWS services, you will understand how and why there are so many different types and options.

We will be studying how databases differ between running them on-premises and in the cloud in terms of access, administration, and maintenance. These topics will appear in the exam, so being able to define the differences is important.

If you already have a database background and are comfortable with the different database types and how they work, please feel free to skip this chapter and go straight to Chapter 3, Understanding AWS Infrastructure. But if you want to go ahead and learn about the differences, then stick around until the end...
