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.

Creating various environments

In this chapter, for the sake of simplicity, we will be creating two different environments for our TODO application to be deployed in – development and production. You might have various other environments when working with software projects of your own, such as staging and demo environments. Additionally, you might also want to create a separate deployment for each pull request on GitHub, run a bunch of tests against it, and then spin down the deployment automatically. CI/CD pipelines can get very involved and we can’t cover all the various ways you could build such pipelines, but the skills you learn in this chapter should cover most of what you need to know to get to advanced CI/CD implementations. Let’s begin.
