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.

Deploying an Aurora cluster

Now we have learned about Aurora and its features, let's deploy our own cluster to practice and to see how the topics we've covered in this chapter work together. We will be deploying an Aurora cluster using the MySQL engine in Serverless mode and we'll then add Global Database. We'll use both the console and awscli for these steps.

Provisioning an Aurora cluster

We'll start by provisioning an Aurora MySQL cluster. We'll be using the Ohio (us-east-1) region. It is important to switch off encryption for this cluster, otherwise we will get an error when creating a global database. In a production environment, we would create a custom KMS key to be used for our multi-region databases, but for now, we will turn off encryption:

  1. Open the AWS console in an internet browser and log in using an account that has privileges to create and modify an RDS instance.
  2. Navigate to Amazon RDS (remember Aurora is a specific type...
