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 SAM CLI

  • 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.
