So, what should most of us be using instead? Suppose I have a 12-factor app that I want to deploy on AWS (directly, not via a third-party PaaS like Heroku). Does anyone know if Amazon ECS is significantly simpler than Kubernetes? Is there a better option than either of those?
I mean, we all know that EC2 is still there, right? An EC2 instance is like a computer. If you have a program, you can run it there. You don't even need a container!
I just don't know a non-sarcastic way to say this. Containers, and especially container runtimes, just aren't necessary. Containers can be _useful_, certainly. But for decades before they were invented, we ran programs on computers and it was pretty good. We can still do that.
The biggest downside was that it took quite a while to spin up new tasks (but that might be Fargate specifically) which hurt us when we were trying to do async things (and we wouldn’t be able to use lambda for many async things because the run time would be too long or the enormous bundle size for a small-ish Python task would exceed Lambda’s limits). It would also make deployments take longer than we wanted (we were really pushing the envelope for frequent, tiny deployments) especially in rollback scenarios.
