We use Kubernetes and spot instances to reduce EC2 billing up to 80%

This is run of the mill for job schedulers (Nomad, Mesos/Marathon, Globus), it’s just more accessible with k8s, containers, and VM spot pricing than historically.

As you mention, definitely don’t do this where persistence is paramount (cache that is expensive to backfill upon recovery, database, etc) but it’s just fine for transient workloads or workloads you can rapidly and safely preempt and resume.

If your instance is stateless, and your app can easily self-heal, there’s lots of computing paradigms you can explore. Serverless/function is also an option.

Of course, at the end of the day rarely is something ever truly stateless.

Eh, I'm currently running an old version of DCOS which does a pretty terrible job of scaling down. Much more than just a scheduler is required to make this work well.

Yeah, your fleet can become fragmented.
