Learning curve. This effectively replaces the docker-compose.yml from the Docker Getting Started tutorial, with a similarly simple sequence of code, and which gives us full access to the AWS platform: The most important is that you cant mount a filesystem. If adequate compute capacity is unavailable, the pipelines compete for resources, and developers have to wait longer to know the effects of their changes. The ApplicationLoadBalancedFargateService construct makes it easy to deploy containerised applications to AWS ECS Fargate. Now, a few questions - I understand Fargate gives u access to just the container and not the underlying host.
