Right, you just need a collection of XFaaS services, which need to be hosted somewhere... So you'll want some container orchestration tool, might as well use k8s.
If setting up a Kubernetes cluster isn't a terrible overhead for us, switching to FaaS would mean we would have more control or less control? I am thinking mainly of migration to another provider.
Maybe we would benefit more if we would have large spikes in resource usage, but we don't.
