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.

Introduction to Step Functions

AWS Step Functions is a workflow management service provided by AWS that enables you to create, execute, and visualize multistep operations or applications.

Think of Step Functions as a tool to streamline complex operations in a serverless environment by connecting and coordinating different tasks. These tasks can range from AWS Lambda functions to AWS Batch jobs to AWS Glue jobs. With Step Functions, you no longer have to manually perform each step of a workflow; instead, you just define the flow of your operations in a state machine and let Step Functions do the heavy lifting for you.

One of the key advantages of using step functions is the ability to keep track and provide a visual representation of the workflow. This makes it easier to understand what’s happening, since you can see exactly what’s going on and where things went wrong, making debugging and troubleshooting easier.

Step functions are widely used in applications...
