What does your infrastructure look like?

In the What are YOU self-hosting? thread, there are a lot of people here who are self-hosting a huge number of applications, but there's not a lot of discussion of the platform these things run on.

What does your self-hosted infrastructure look like?

Here are some examples of more detailed questions, but I'm sure there are plenty more topics that would be interesting:

• What hardware do you run on? Or do you use a data center/cloud?
• Do you use containers or plain packages?
• Orchestration tools like K8s or Docker Swarm?
• How do you handle logs?
• How about updates?
• Do you have any monitoring tools you love?
• Etc.

I'm starting to put together the beginning of my own homelab, and I'll definitely be starting small but I'm interested to hear what other people have done with their setups.
