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 created and integrated Lambda functions and an API gateway to replace the RDS and ECS services. We created a DynamoDB table and set up a way to automatically seed it when deploying the stack and created a step function state machine linked to SES. We also set up a GET request to fetch all data from the DynamoDB table and a POST request to insert data into the same table and trigger the state machine. Finally, we added the API Gateway and DynamoDB constructs to our CDK stack and removed the ECS, RDS, and VPC constructs from the Stack. As you’ve experienced, the process of applying changes and testing serverless logic can be time-consuming. In the next chapter, we’ll explore ways to streamline building serverless applications, specifically by optimizing our local environment for faster and more efficient development.
