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.

Streamlined Serverless Development

Previously, we covered how to convert our code into a serverless architecture by replacing ECS, RDS, and VPC services with API Gateway, Lambda functions, and DynamoDB. But there’s still room for improvement in the development process.

Even though using serverless technologies simplifies maintenance after deployment, we can still optimize the way we work on the code locally.

In this chapter, we’ll be covering the following topics:

  • Common problems with serverless development
  • Running Lambda application logic locally and integrating it with a local express server
  • How to run AWS services locally using the LocalStack toolset

By the end of this chapter, you will be aware of the problems in serverless-oriented development, and your code will have been streamlined to the point where you will be able to develop infrastructure as code (IaC) and test it locally before deploying it to AWS.
