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.

In this chapter, we discussed how to streamline serverless development by using a local express server and LocalStack for a local cloud environment. We provided step-by-step instructions for installing and running LocalStack and cdklocal, configuring the DynamoDB endpoint to point to LocalStack, and importing the same function used in the deployed Lambda function to the local server. Additionally, we showed how to run commands and make requests to the local development server to test the code’s functionality. The overall objective of this process is to enable the local testing and development of AWS cloud infrastructure without incurring costs or impacting production resources. In the next chapter, we will introduce the concept of indestructible serverless application architecture (ISAA), a design pattern for building serverless applications that are highly resilient and can scale infinitely.
