-Amplify (Gen 2) backends are defined using TypeScript, and enable you to collocate resources depending on their function. For example, you can author a [Post Confirmation trigger for Amazon Cognito](https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-post-confirmation.html) right next to your auth's resource file.

-Backends can be extended using the [AWS Cloud Development Kit (CDK)](https://docs.aws.amazon.com/cdk/v2/guide/home.html). By leveraging CDK you can build using any AWS service, such as an Amazon S3 bucket that authenticated users have read and write access to. You can get started by installing AWS CDK:

-```bash
-npm add --save-dev aws-cdk-lib

-Depending on the Node.js package manager you are using, you may encounter warnings where it is now unable to resolve the peer dependency version `@aws-amplify/backend` has on `aws-cdk-lib`. If you encounter a warning similar to the following, re-install the version specified in the warning text:
-
-```
-npm WARN Could not resolve dependency:
-npm WARN peer aws-cdk-lib@"~2.103.0" from @aws-amplify/[email protected]
