Continuous Deployment on Amazon ECS
Introduction
- The presenter, SA Kumar Sala, is a Specialist Solution Architect for Containers at AWS, helping customers deploy and modernize their container workloads on AWS.
- Customers want to release new versions of their applications faster, without spending time managing deployment infrastructure and manually rolling back deployments.
- This session will cover how Amazon ECS features enable faster, reliable, and automated deployments with rollback capabilities.
Release Process Stages
- The typical release process stages are:
- Source: Developers commit code to the repository, and peer review is done.
- Build: Artifacts are generated, including the container image, which is pushed to a repository like Amazon ECR.
- Test: Integration, load, and security testing are performed.
- Production: Observability tools are deployed to monitor the application.
Continuous Integration and Continuous Deployment
- Continuous integration happens between the Source and Build stages, automatically building artifacts on code commits.
- Continuous deployment is the automated process from Source to Production, with no manual steps.
- The build is triggered on code commit, and the new container image is pushed to the registry.
- Automated testing is performed, and if successful, the application is automatically deployed to production.
- If there are issues between Test and Production, the deployment is automatically rolled back.
Amazon ECS and Continuous Deployment Goals
- Amazon ECS handles the deployment and run stages of the release process.
- Continuous deployment goals:
- Automatically deploy to staging for testing.
- Ensure safe production deployments without affecting customers.
- Deliver faster with increased deployment frequency.
- Reduce lead time and failure rates.
Amazon ECS Deployment Features
- Amazon ECS supports rolling and blue-green deployments.
- The demo focuses on rolling deployments and the deployment circuit breaker feature.
- The deployment circuit breaker automatically monitors task launches and rolls back to the last known good state if there are deployment failures.
- Enabling the deployment circuit breaker is a one-click setup in the Amazon ECS console.
Live Demo
- The demo sets up a staging and production cluster, each with an ECS service running the "hello server" application.
- The presenter introduces a bug and a version change in the application code and pushes it to the repository.
- The code pipeline is triggered, and the deployment circuit breaker is enabled for both the staging and production services.
- The deployment to the staging environment fails due to the introduced bug, but the application remains available as the deployment is automatically rolled back.
- The pipeline then successfully deploys the updated application to the staging environment, and the test stage is executed.
- Once the tests pass, the application is deployed to the production environment.
Key Takeaways
- Amazon ECS provides built-in features for reliable and automated deployments, including the deployment circuit breaker.
- The deployment circuit breaker automatically monitors and rolls back deployments in case of failures, ensuring the application remains available.
- Enabling the deployment circuit breaker is a simple one-click setup in the Amazon ECS console.
- Amazon ECS helps achieve continuous deployment goals by automating the release process and reducing lead time and failure rates.
