Overview of this book

The AWS Certified Database – Specialty certification is one of the most challenging AWS certifications. It validates your comprehensive understanding of databases, including the concepts of design, migration, deployment, access, maintenance, automation, monitoring, security, and troubleshooting. With this guide, you'll understand how to use various AWS databases, such as Aurora Serverless and Global Database, and even services such as Redshift and Neptune. You’ll start with an introduction to the AWS databases, and then delve into workload-specific database design. As you advance through the chapters, you'll learn about migrating and deploying the databases, along with database security techniques such as encryption, auditing, and access controls. This AWS book will also cover monitoring, troubleshooting, and disaster recovery techniques, before testing all the knowledge you've gained throughout the book with the help of mock tests. By the end of this book, you'll have covered everything you need to pass the DBS-C01 AWS certification exam and have a handy, on-the-job desk reference guide.

Overview of RDS

AWS RDS is a managed database service. What this means is that AWS offers a wrapper around a relational database that manages many of the functions that are normally carried out by a DBA. For example, RDS can take backups by default without the DBA needing to schedule them. RDS aims to reduce the amount of time a DBA spends doing day-to-day administration work, allowing them to focus on areas such as performance tuning.

To use RDS, you need to consider four things:

  • Which database type do I want?
  • How much compute (CPU and memory) do I need?
  • How much storage do I need?
  • Do I need to consider high availability or disaster recovery options?

With that information and the VPC that we built in Chapter 3, Understanding AWS Infrastructure, you can deploy an RDS that's ready to store the data for your application.

To be able to decide on these four questions, first, let's look at what databases RDS supports.
