lol, even if you have complex apps there are always easier solutions than Kubernetes. It is evident that you have never run such an app and are just talking about it. Otherwise, you would know the issues you would encounter with every update due to breaking changes. Not to mention that you need a high level of expertise and a dedicated team, which costs far more than running an app on Fargate. Recommending a managed Kubernetes cluster is nonsense, as it goes against the whole purpose of Kubernetes itself.
