- Allows us to define our cloud infrastructure using a familiar programming language such as JavaScript/TypeScript, Python, Java and .NET
- The CDK framework contains high level components called constructs
- The code is transpiled into a CloudFormation template (JSON/YAML)
- With CDK we can deploy infrastructure and application runtime code together
- This is great fro Lambda functions
- Or great for Docker containers which can be deploy to ECS/EKS
- SAM:
- Serverless focused
- We write our templates in JSON or YAML
- Great for quickly getting started with Lambda
- Leverages CloudFormation
- CDK:
- Superset of CloudFormation, supports every AWS service
- We write infra in a programming language we know (see above)
- Leverages CloudFormation
- CDK + SAM:
- We can use SAM CLI to locally test CDK apps
- We must first run
cdk synth- this will generate CFN template which we can invoke with SAM cli
