Just shut down my last OpenBSD virtual machine online at Vultr. This means that about any conventional server I’ve been running has now been migrated. Exception is a router where I’m pretty happy with what OpenBSD has built-in over proprietary options from such as Unifi. 

Cost management is an interesting perspective with self-hosted Kubernetes. Not necessary much cheaper compared to a minimum of what I need, but it brings a central vantage point for control.
