  • Templates

    • Manage and provision resources using Infrastructure as Code (IaC).

      • Environment Template – a shared infrastructure used by multiple applications or resources.

        • Standard Environment Template – AWS Proton provisions infrastructure for your environment.

        • Customer-managed Environment Template – provision your own shared resources.

      • Service Template – the infrastructure required in a particular environment to deploy and manage a single application or microservice.

    • Supports the following IaC providers:

      • AWS CloudFormation

      • Terraform

    • Template bundles

      • An IaC file with a manifest YAML file.

      • A schema YAML file for IaC file input parameter definitions.

    • Versioned templates

      • Minor version – backward compatibility is supported.

      • Major version – backward compatibility is not supported

      • Compatibility is determined solely based on the schema.

    • Template sync configurations

      • To allow AWS Proton sync from template bundles located in registered git repositories.

      • If it detects a template bundle change, it creates a new minor or major version of its template.

  • Environments

    • It represents the set of shared resources and policies into which AWS Proton services are deployed.

    • Contains resources that will be shared across AWS Proton service instances.

      • VPC

      • Clusters

      • Load Balancers

      • API Gateways

    • Environment provisioning options:

      • AWS-managed provisioning

      • AWS-managed provisioning to another account

      • Self-managed provisioning

    • You can create an AWS Proton environment from one account and provision using environment account connections.

  • Services

    • A service is an instantiation of a service template, including service instances and pipelines.

    • A service instance is a collection of AWS infrastructure resources used to run an application in an environment.

    • You can create a service template with or without a service pipeline.

    • When you build a service, you must create at least one service instance.

  • Components

    • Allows you to define supplemental AWS infrastructure resources that a certain application may require in addition to those provided by the environment and the service instance.

    • Directly defined components enable you to define and provision additional infrastructure.

    • Components states:

      • Attached

        • Extends the infrastructure of a service instance.

        • It is associated with a service instance and an environment.

      • Detached

        • Maintain component infrastructure between service instance attachments.

        • It is associated with an environment.

  • Repositories

    • A repository link is a set of properties that can be used by AWS Proton when connecting to a repository.

    • Code Repository

      • It is where you store the application code.

      • Used for code deployment.

    • Template Repository

      • It is where you store template bundles.

      • Used for template sync.

      • You can also upload your templates to Amazon S3 and use the AWS Proton API to access them.

    • Infrastructure repository

      • Host rendered infrastructure templates.

      • Used for self-managed provisioning of resource infrastructure.

    • Pipeline repository

      • Used to create pipelines.

      • Used for self-managed provisioning of pipelines.


  • You can use EventBridge to receive notifications when the state of AWS Proton provisioning workflows changes.

  • An event rule captures status changes for your AWS Proton service.

  • Events are made up of rules that include an event pattern and targets.

    • Event pattern – each rule is expressed as an event pattern, which includes the source, type, and event targets.

    • Targets – create a target service to send notifications, collect state information, take corrective action, start events, or perform other tasks.
