Where do Custom Runtimes Run?

Custom Runtimes execute in the Runtime you specify. They do not execute in Prodvana's control plane. This gives you the confidence that they are operating with your security model.

Why not a CRD or something else?

We want to keep building simple and accessible to engineers.

Do I have to use Kubernetes?

For now yes. However, Custom Runtimes' interface is flexible enough that we can add additional runners such as Lambda, Cloudrun and plan to do so in the future.
