Yes, the last two companies I've worked for migrated to AWS Fargate and Serverless/Lambda. There are some advantages to using k8s when you have large stateless applications that need to scale, but it requires well thought out patterns for things like caching and involvement with the dev team from the beginning. Most small to medium size companies get no real benefit from Kubernetes as it introduces a lot of devops overhead and rot (examples: the companies that chose to use Skaffold instead of Helm, or customized deploy scripts that don't make sense to developers and aren't integrated into a CI/CD pipeline)
