Define your infrastructure with AWS SAM

Now that you have created your project, you are ready to define your application infrastructure with AWS SAM. Do this by configuring your AWS SAM template to define your application's resources and properties, which is the template.yaml file in your AWS SAM project.

The topics in this section provide content on defining your infrastructure in your AWS SAM template (your template.yaml file). It also contains topics on defining resources for specific use cases, such as working with Lambda layers, using nested applications, controlling access to API Gateway APIs, orchestrating AWS resources with Step Functions, code signing your applications, and validating your AWS SAM template.

Topics
