Overview of this book

With this Learning Path, you’ll explore techniques to easily manage applications on the AWS cloud. You’ll begin with an introduction to serverless computing, its advantages, and the fundamentals of AWS. The following chapters will guide you on how to manage multiple accounts by setting up consolidated billing, enhancing your application delivery skills, with the latest AWS services such as CodeCommit, CodeDeploy, and CodePipeline to provide continuous delivery and deployment, while also securing and monitoring your environment's workflow. It’ll also add to your understanding of the services AWS Lambda provides to developers. To refine your skills further, it demonstrates how to design, write, test, monitor, and troubleshoot Lambda functions. By the end of this Learning Path, you’ll be able to create a highly secure, fault-tolerant, and scalable environment for your applications.

Creating a database read-replica

This recipe will show you how to create an RDS read-replica. You can use read-replicas in order to increase the performance of your application by off-loading database reads to a separate database instance. You can provision up to five read-replicas per source DB.

Read-only database slaves

Getting ready

You will need an RDS DB deployed with backup retention enabled. We are going to build upon the DB deployed in the previous Creating a database with automatic failover recipe.

You're going to need the following values:

  • The identifier for your source RDS instance, for example, eexocwv5k5kv5z
  • A unique identifier for the read-replicate we're going to create, for example, read-replica-1

How to do it...

In the AWS CLI, type this command:

aws rds create-db-instance-read-replica \
  --source-db-instance-identifier <source-db-identifier> \
  --db-instance-identifier <unique-identifier-for-replica>

How it works...

RDS will now go ahead and create a new read-replica...
