I think Cloud Run, Fargate and Azure Container Apps all fall more into the category of "platform-as-a-service" rather than "function-as-a-service", in the same way that EKS or GKE could be categorised as a PAAS. EDIT: I also think they're _excellent_ to use for development. The migration from ECS + Fargate to EKS + EC2 is not a difficult migration from the application side, and can be done relatively piecemeal, in my experience.
