Migrating from bare Metal Machines to AWS ECS
summary
AppLike moves its PHP monolith from bare metal/EC2 into AWS ECS containers, replacing Vagrant with Docker Compose for local parity and adding DotEnv for Symfony so identical images run across environments. Deployment uses ecs-deploy and AWS SSM Parameter Store for secrets; rolling upgrades and rollbacks work but cold-starts and large image pulls slow startup. Operational surprises: ECS task placement requires isolating API and workers, and ECR account limits (~4,000 images) force aggressive lifecycle policies.
