Another alternative for managing containers on a cluster of machines is AWS ECS. It has been around for a while and integrates really well with other AWS services (e.g. Cloudwatch, ALB). Unlike Kubernetes the scheduler is proprietary, but the agent running on individual instances is open source.

We've been using ECS for a while together with Terraform for managing the whole infrastructure in immutable and declarative way, and it has been great so far.
