Overview of this book

Amazon Web Services (AWS) is a bundled remote computing service that provides cloud computing infrastructure over the Internet with storage, bandwidth, and customized support for application programming interfaces (API). Implementing these services to efficiently administer your cloud environments is a core task. This book will help you build and administer your cloud environment with AWS. We’ll begin with the AWS fundamentals, and you’ll build the foundation for the recipes you’ll work on throughout the book. Next, you will find out how to manage multiple accounts and set up consolidated billing. You will then learn to set up reliable and fast hosting for static websites, share data between running instances, and back up your data for compliance. Moving on, you will find out how to use the compute service to enable consistent and fast instance provisioning, and will see how to provision storage volumes and autoscale an application server. Next, you’ll discover how to effectively use the networking and database service of AWS. You will also learn about the different management tools of AWS along with securing your AWS cloud. Finally, you will learn to estimate the costs for your cloud. By the end of the book, you will be able to easily administer your AWS cloud.

Canary deployment is a popular deployment method in the cloud. It allows you to deploy new versions of your resources alongside your old resources, gradually and selectively directing parts of your traffic to the new resource.

By directing a small portion of your traffic to your new resources, you can get valuable real-world data and metrics. This means you don't need to engage in a big bang deployment—where you switch over all of your traffic at once.

It also gives you more flexibility in terms of troubleshooting and monitoring; if you see errors for your new resources, you can redirect the traffic back to your old resources while you investigate.

In this recipe, we will create the resources necessary to do a DNS-based canary deployment, and cut traffic from one resource to another (that is, old to new).

Getting ready

This recipe requires a few things to be in place:

  • A Route 53 hosted zone for your domain suffix
  • Existing DNS records for your old and new resources/endpoints...
