All 4 maps servers should have a Varnish memory-only role enabled.
Approach should probably still be similar to MW - two instances per machine, small and large memory allocation.Basically, we need:
[ ] maps.svc.codfw.wmnet:4000 LVS -> maps-test200[1-4].codfw.wmnet:4000 (HTTP, The frontend instance would do hotspot handling, or call the backend varnish based on URL clustering. The backend Varnish will use the localhost's kartotherian to generate tileuse /static/ for health monitor)
[ ] maps cache cluster in eqiad (standard 2layer setup like "upload", with fresh/minimal VCL, possibly with a fallback to another server just in case the local kartotherian is dead. Max & Yuri should get Varnish admin access.
* Varnish forwards to localhost port 4000can reuse the recently decommed cp104[34] machines for now)
[ ] maps.wikimedia.org LVS/DNS setup into new IP for maps cache cluster
