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.

You can use S3 cross-region replication and restore, but there will be a long downtime, so this is not the best solution.

Using DMS will allow a migration with minimal downtime, so this is the best solution.

There is no cross-region replication for RDS SQL Server.

This is a method to reduce storage allocated but it will involve downtime.

Using CDC will allow the storage to be reduced with minimal downtime and is the best solution.

Using a backup and restore method may reduce storage needs but it...
