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.

Chapter 8: Neptune, Quantum Ledger Database, and Timestream

In this chapter, we are going to explore and learn about three different Amazon Web Services (AWS) database technologies: Neptune, Quantum Ledger Database (QLDB), and Timestream. Each of these databases supports a specific workload type. All three are fully managed, and QLDB and Timestream are serverless databases.

Neptune is a graph database that allows you to run queries to quickly find out the connections and relationships between data items. QLDB is a database that works like an audit trail and does not allow any data to be deleted or changed. Timestream is a time-series database that allows you to work with data closely connected to timestamps, allowing you to keep an ordered record of events.

This chapter includes a hands-on lab where we will deploy, configure, and explore Neptune, QLDB, and Timestream instances, including how we can monitor and access them.

In this chapter, we're going to cover the following...
