AWS Serverless Application Repository

AWS Serverless Application Repository Cheat Sheet

  • The AWS Serverless Application Repository is a managed repository for deploying and publishing serverless applications.

  • You can also use pre-built applications instead of cloning, building, packaging, and publishing source code to AWS before deploying it.

  • Each application includes an AWS SAM template that specifies the AWS resources that will be used.

Publishing Applications

  • Use an AWS SAM template to define your application.

  • To publish a serverless app, you can use the following to upload your code:

    • AWS Management Console


    • AWS SDKs

  • When you publish an app, it is initially set to private and only accessible to the AWS account that created it.

  • You can deploy and share your app by setting it to:

    • Private

      • Not shared with any other AWS accounts.

      • Only accessible to the AWS account that created it.

      • You have permission to deploy applications created with your AWS account.

    • Privately Shared

      • Shared to a specific set of AWS accounts.

      • Accessible in the AWS Region in which they are created.

      • You have permission to deploy applications shared with your AWS account.

    • Publicly Shared

      • Shared with everyone.

      • Accessible to all AWS Regions.

      • You have permission to deploy any publicly shared application.

  • A link to the source code is included in publicly shared applications.

  • If the public app is deployed to another Region, AWS SAR copies the app deployment artifacts to an Amazon S3 bucket in the destination Region.

  • By sharing Lambda layers, you can deploy an instance of your layer to another AWS account.

Deploying Applications

  • To deploy an application, you must have permission to do so (see permissions above).

  • Before deploying an app, AWS SAR also checks the application template for:

    • IAM roles

    • AWS resource policies

    • Nested applications specified by the template

  • You can only search for and browse applications for which you have permission:

    • Created using your AWS account

    • Privately shared with your AWS account

    • Publicly shared

  • Use AWS Console or AWS CLI to deploy and update applications.

AWS Serverless Application Repository Monitoring

  • Create a trail in AWS CloudTrail to capture all API calls.

  • Even if you haven’t configured a trail, you can still view the most recent events in the CloudTrail console’s Event history.

AWS Serverless Application Repository Pricing

  • You are charged for AWS resources used in the applications you deploy.
