AWS SAM vs AWS CDK

To Nha Notes | Oct. 11, 2023, 9:56 a.m.

AWS SAM and AWS CDK are both open-source frameworks for building applications using infrastructure as code (IaC). Here are some key differences and similarities between them:

• AWS SAM:

  • AWS SAM is template-based using JSON or YAML1.
  • You can use the AWS SAM CLI to locally test and build serverless applications defined using AWS CloudFormation or AWS SAM templates1.

• AWS CDK:

  • The AWS CDK uses languages such as Python or Node1.
  • With AWS CDK, you can use code, not config, to define your application2.

• Together:

  • You can use the AWS SAM CLI to locally test and build serverless applications defined using the AWS CDK1.
  • CDK and SAM can be used together to create serverless applications. You will use CDK to define and create your AWS resources, and you will use SAM to test Lambda, API Gateway and DynamodDB resources1.

So, while they have different approaches (template-based for SAM and language-based for CDK), they can be used together effectively for building, testing, and deploying serverless applications.
