While we build our open source, cloud agnostic Heroku/Cloud Foundry-like Paas - Pipeline - on top of Kubernetes, we continue to launch lots of clusters on different cloud providers. Most of these clusters are launched on spot or preemptible instances, and managed by Hollowtrees. However, there are many smaller development clusters, control planes, instances and PoCs we launch that are marginally related to, or launched with, Pipeline. Naturally, these have an associated cost that we want to keep tight control over.
