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 automation techniques

One of the fundamental benefits of cloud technologies is the ability to use code to describe and build your infrastructure. This is called Infrastructure as Code (IaC). You can use IaC techniques on-premises as well but often, you will be limited by physical restrictions such as running out of storage within your storage arrays or running out of physical CPU cores on your virtual machine coordinators (hypervisors, for example). While the same physical restrictions can impact a cloud deployment, a capacity outage on a cloud platform is extremely rare. Using IaC on-premises is also often complex due to a wide variety of technologies that do not use a command interface, programming language, or application programming interfaces (APIs).

IaC allows you to create code that can be run multiple times to create exact copies of the same infrastructure, which is extremely useful when you're creating test and development environments. You can use code...
