Define AWS specific configuration.


  • region: AWS region ID of the region you’ll deploy this project to
    • If not specified, defaults to us-west-2
  • profile: name of the profile you prefer to use with this project, as defined in your local AWS profile
    • Can also be specified in AWS_PROFILE environment variable
    • Required to deploy to AWS
  • runtime: Lambda runtime, can be one of:
    • nodejs14.x (default), nodejs12.x, deno, python3.8, python3.7, python3.6, ruby2.7, ruby2.5
    • Unsupported by Sandbox: go1.x, dotnetcore3.1, dotnetcore2.1, java11, java8
  • bucket: bucket (in same region) for CloudFormation deployment artifacts
    • If not specified, a secure deployment bucket will be auto-created for your app
  • apigateway: API Gateway API type, can be one of:
    • http (default) - HTTP API + Lambda payload format version 2.0
    • httpv2 – aliased of http
    • httpv1 - HTTP API + Lambda payload format version 1.0
    • rest - REST API + original API Gateway payload format
  • architecture: Lambda CPU Architecture of your functions. (Added in Architect 9.1)
    • x86_64 (default) - 64-bit x86 architecture
    • arm64 - (only available in certain AWS regions) 64-bit ARM architecture

Alternatively, if you want a less granular approach, you can declare your preferred region and profile in your .bashrc (more information here).

If you have AWS exports in your .bashrc and @aws specified in your app.arc project, the @aws section will win.


For example, to deploy to the northern California AWS AZ with your AWS work profile’s credentials, use:

region us-west-1
profile work
  "aws": {
    "region": "us-west-1",
    "profile": "work"
  region: us-west-1
  profile: work
