AWS CDK in Practice

By: Mark Avdi, Leo Lam

Overview of this book

As cloud applications are becoming more complex, multiple tools and services have emerged to cater to the challenges of running reliable solutions. Although infrastructure as code, containers, and orchestration tools, such as Kubernetes, have proved to be efficient in solving these challenges, AWS CDK represents a paradigm shift in building easily developed, extended, and maintained applications. With AWS CDK in Practice, you’ll start by setting up basic day-to-day infrastructure while understanding the new prospects that CDK offers. You’ll learn how to set up pipelines for building CDK applications on the cloud that are long-lasting, agile, and maintainable. You’ll also gain practical knowledge of container-based and serverless application development. Furthermore, you’ll discover how to leverage AWS CDK to build cloud solutions using code instead of configuration files. Finally, you’ll explore current community best practices for solving production issues when dealing with CDK applications. By the end of this book, you’ll have practical knowledge of CDK, and you’ll be able to leverage the power of AWS with code that is simple to write and maintain using AWS CDK.

DNS with Route 53

Let’s say you own the domain name and you would like to assign the following two DNS records to the frontend and backend portions of our TODO application:


To do this, you would have to let AWS’s DNS routing service, Route 53, take care of your domain’s DNS records. You potentially have a domain name that you’ve parked and that’s not currently used. If you do, great. If not, you can always register the cheapest possible domain name to complete this section of this book.

This is important because you will never release a web application with randomly assigned load balancer URLs, the likes of which we saw in the previous chapter. AWS Route 53 also has a domain registration service. Let’s look at how it works:

  1. Sign in to the AWS console and, in the top search bar, type in Route 53. Click on the result.
  2. From the left-hand panel, click Registered...
