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.

DMS can also create target database tables for you, if they do not already exist, in a similar way to SCT. However, it is much less powerful and only converts the minimal database objects that are required for a successful migration. You would still need to manually create most indexes, views, and database code.

DMS has three main components:

  • Endpoints: These allow DMS to connect to databases that are hosted in different VPCs and on-premises.
  • Replication Instance: This is an EC2 instance that's used to run the migration.
  • Tasks: These are the jobs that control and manage the migration process.

To use DMS, you must provide a source...
