+
+Standards for provisioning of VMs and physical hosts.
+
+# Alpine Linux
+
+Our standard loadout uses Alpine Linux for all hosts and guests.
+
+- **TODO**: ns1 and ns2 are on Debian, they need to be reprovisioned (add an ns3
+  while we're at it?)
+
+# Physical hosts
+
+## VM hosts
+
+Our current VM hosts won't scale much further. We need to figure out a better
+hardware loadout for these going forward.
+
+## High performance VM hosts
+
+For performance critical services (presently only git.sr.ht demands this), we do
+have a standard loadout:
+
+- AMD EPYC 7402 (24 cores, 48 threads)
+- Micron 36ASF2G72PZ-2G6F1 RAM (4x, 64G total)
+- 1x NVMe for host system, ext4; WD Black 1T
+- 4x SSD on SATA, direct passthrough to guest
+
+This is spec'ed to CPU and I/O intensive workloads.
+
+## Build hosts
+
+builds.sr.ht uses dedicated build runners. Our current standard is:
+
+- AS-1013S-MTR SuperMicro barebones
+- AMD EPYC 7281 (16 cores, 32 threads)
+- M393A4K40CB2-CTD RAM (4x, 128G total)
+- 1x NVMe for root, ext4; WD Black 1T
+- 3x HDD on SATA for /var, ZFS; 1T each, various vendors/models
+
+This configuration supports up to 16 parallel build slots.
+
+# Virtual machines
+
+There is no standard loadout - tune the specifications for the task at hand.
+Generally limit 1 VM == 1 service, and tune accordingly.
