Fargate is excellent. It takes the machine management and host management out of running containers. If you run docker on ec2, you need to manage the scaling of the hosts and containers, and also the packing of both. With fargate you just say "I want 1 vcpu and 2gb ram, and scale at 80% utilisation". Ive worked on projects that were too big to be cost effective to run with that model but for personal projects and for my current job it's excellent.
