AWS Proton Cheat Sheet

• A managed delivery service for deploying container and serverless applications.
• Uses templates to define and maintain standard application stacks, which include the architecture, infrastructure resources, and the CI/CD pipeline.
• AWS Proton will end support on October 7, 2026.
• After this date:
  • The AWS Proton console and AWS Proton resources will no longer be accessible.
  • Deployed infrastructure remains intact.
• All existing templates, environments, services, components, and pipelines remain for historical and exam awareness.

Concepts

Templates

• 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 – you 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
  • Allows AWS Proton to sync from template bundles located in registered git repositories.
  • If a change is detected in a template bundle, AWS Proton creates a new minor or major version of its template.
• Supports service sync configurations to automatically create new template versions when changes are detected.

Environments

• 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 building a service, you must create at least one service instance.
• Supports CodeBuild provisioning for service pipelines.

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.
• Component states
  • Attached
    • Extends the infrastructure of a service instance.
    • Associated with a service instance and an environment.
  • Detached
    • Maintain component infrastructure between service instance attachments.
    • 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 – where you store the application code; used for code deployment.
• Template Repository – where you store template bundles; used for template sync.
• Templates can also be uploaded to Amazon S3 and accessed via the AWS Proton API.
• Infrastructure Repository – hosts rendered infrastructure templates; used for self-managed provisioning of resource infrastructure.
• Pipeline Repository – used to create pipelines; used for self-managed provisioning of pipelines.

AWS Proton Monitoring

• 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
  • 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.

AWS Proton Pricing

• You are charged for AWS resources that you create to store and run your application.
