I migrated a company from k8s to ECS/Fargate in 2019. Kubernetes is very flexible, but I opted for simplicity.
The result of the migration was that there is little underlying infrastructure to maintain, and ongoing operational costs were lowered by 50% year over year. The CTO and I liked the setup so much, we started converting another large client of theirs. I followed up with them at the beginning of 2022 to see how things were going, and they still love it. There is so little maintenance, and now they have more time to focus on what they do best–Software!
Other options on the horizon that I'm testing include utilizing AWS Copilot with ECS/Fargate, and/or Copilot with Amazon App Runner.
I have settled on the ECS camp as well. Took a run at Kubernetes and was blown away by the complexity. With ECS/Fargate I don't spend any time on it. It just works for our setup.
I still wonder from time to time if I am missing something not going Kubernetes.
Are you big enough to need terraform? If the answer is yes, you may have a good justification to move to kubernetes migrate tf->k8s with lots of benefits for the app teams (if they care). If you're just yolo setup your cloud in AWS web console and you're fine with that, then you may not see much lift. A good reason to use declarative (often infrastructure as code) approach to deployments is that it improves bus factor and the ability to hire people who can pick up and maintain the infrastructure.
Under the hood it means that the `cdktf synth` command ultimately generates Terraform configuration that can be executed like any other Terraform config. It's definitely not a case of Terraform trying to be like CDK. Each has it's strengths, choose whichever makes the most sense for your workflow.
I use AWS Copilot and find it to be really easy to use and helpful. It is still a pretty young project and as such doesn't really handle all the edge cases, but for the things it supports, it makes using ECS even easier than it already is.
