In this 'Back to Basics' episode, Seb shares his journey of using containers to ensure consistent code behavior across environments. He explores architectural patterns for deploying containerized applications on AWS, leveraging services like Amazon ECS, AWS Fargate, ECR, CodeBuild, CodeDeploy, and CodePipeline. Seb demonstrates how to automate container builds, push images to ECR, run containers on Fargate or ECS clusters, load balance traffic, and set up a CI/CD pipeline for automated deployments. He covers key aspects such as running containers as Tasks vs. Services, serverless deployments with Fargate, integrating load balancers, automating testing and rollbacks, and triggering deployments on code changes. Whether you're new to containers or looking to optimize your deployments, this episode provides valuable insights into containerizing applications on AWS.
