Description

The AWS CDK construct library contains classes that shape the AWS resources in your stack and come with proper defaults that allow you to focus on developing your application without worrying too much about resource details. This is useful for developing prototypes or smaller applications quickly and establishing a proof-of-concept, but what happens when the application or your development team grows?

Writing your own custom CDK constructs provides the following benefits:

  • Establish organization standards to follow best practices
  • Ensure AWS resource conventions continue to be adhered to as your application or team grows
  • Reduce the amount of code developers need to write by extracting repetitive sections

In this lab, you will refactor an existing CDK application by creating your own custom S3 construct. The process of writing your own custom constructs outlined in this lab can be applied to your own projects and development teams to fit your specific needs.

Learning Objectives
