Overview of this book

AWS is an on-demand remote computing service providing cloud infrastructure over the internet with storage, bandwidth, and customized support for APIs. This updated second edition will help you implement these services and efficiently administer your AWS environment. You will start with the AWS fundamentals and then understand how to manage multiple accounts before setting up consolidated billing. The book will assist you in setting up reliable and fast hosting for static websites, sharing data between running instances and backing up data for compliance. By understanding how to use compute service, you will also discover how to achieve quick and consistent instance provisioning. You’ll then learn to provision storage volumes and autoscale an app server. Next, you’ll explore serverless development with AWS Lambda, and gain insights into using networking and database services such as Amazon Neptune. The later chapters will focus on management tools like AWS CloudFormation, and how to secure your cloud resources and estimate costs for your infrastructure. Finally, you’ll use the AWS well-architected framework to conduct a technology baseline review self-assessment and identify critical areas for improvement in the management and operation of your cloud-based workloads. By the end of this book, you’ll have the skills to effectively administer your AWS environment.

Promoting an RDS read replica to master

We're going to show you how to promote an RDS read replica to be a primary instance. There are a few reasons you might like to do this:

  • To handle a table migration that would typically cause a large amount of downtime, especially when messing with columns or indexes
  • Because you need to implement sharding
  • Recovery from failure, should you choose not to deploy your existing primary in multi-AZ mode (not recommended)

Getting ready

You're going to need the unique ID that has been assigned to an RDS read replica. If you followed the Creating a database with automatic failover and Creating a database read replica recipes, then you'll be all set.
