The article states they moved all of their stateless stuff to ECS, stateful stuff to Docker containers on EC2, batch jobs to AWS Batch, and event-driven stuff to AWS Lambda. Previously they ran 47 different K8s clusters on 3 different clouds. Given that all of their needs could be satisfied with 4 AWS services, and for nearly half a million dollars a year cheaper than their previous setup, I think running 47 different clusters in 3 clouds was insane.
