If you have a mix of different systems both on-prem and cloud, and tie them together in various ways using VPNs, mesh or otherwise, create a graph using something like Excalidraw to give yourself a refresher on how everything connects. You want machines, hostnames, IPs, ports, and a list of services. You don’t have to be fancy by creating visual representations of each service, just a bulleted list. You only really have to update this when adding or removing compute.
If you’re running services on lots of different nodes, a spreadsheet that just maps services to whatever URL you use access them, to whichever backend server is running them. This takes minimum effort and gets you 90% of the way there.
