That doesnt really have anything to do with this issue. Lemmy can absolutly be hosted in AWS via ECS (or EKS if you love Kubernetes). Hell, it could be hosted directly on EC2 if preferred.
Federation as a whole is more resilient because each operator can chose whatever hosting solution they prefer. But if your particular server happened to be hosted in AWS in the useast1 region; your shit was gonna be a bit busted.
