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.

Cheat sheet

This cheat sheet summarizes the main key points from this chapter:

  • SCT is used to assess and convert a database from one engine into another for a heterogeneous migration.
  • SCT can also be used to assess a homogenous migration in RDS to highlight features that are not supported in your source database.
  • Once you have converted a schema using SCT, you can use DMS to migrate the data into the empty schema and tables.
  • DMS can also be used to create a schema in your target database, but you have no control over the data types that are created in the table.
  • DMS can be used in both full load and CDC mode.
  • To run a DMS task, you need a replication instance, a source endpoint, and a target endpoint.
  • You can run multiple tasks to migrate a single source database to improve performance.
  • For very large databases or complex conversions, you can use AWS Snowball Edge with SCT and DMS to assist with the migration.
