We have two appservers but five memcached nodes, that seems off.

Not really, given the amount of traffic beta receives, and the fact we don't have load-balancing so it's hard to distribute requests more.

Most of the VMs you listed above are still in use, even if no one logs into them or touches them since some time.

I would ask why do we have mailman VMs in deployment-prep, OTOH. It seems quite off-topic there.

The two stopped changeprop VMs can be removed, I think, but I'd ask @hnowlan to confirm that's the case

It's the Mailman v3 testing instance as per T52864.

Indeed but this project is huge and this is list of all VMs, if we just audit and clean 10-20%, it frees up 20-40 VCPUs. For comparison, "meet" project has 8 VCPUs as the quota.

Yup, that's what I'm working on: https://lists-beta.wmflabs.org I can also request a dedicated project if you think that's better.

I've marked this as "Needed" on behalf of Platform Engineering team. This is the primary and only poolcounter node, and is indeed being used per LabsServices.

cache-text, cache-upload, etcd, ircd, and memc are most certainly also still in use and we need at least one of each.

For memc we can most likely size down, I don't think we added this many intentionally but rather added new ones during rebuilds/upgrades and maybe left old ones?

cc @RLazarus Do you know if any of these were used for tests, and whether we could e.g. get a way with just one or two of the deployment-memc* instances? If so, where do we need to check for configs and update things etc. is the latest one the "right" one to keep?

I don't know much about this, but @Joe addressed the same question in T257118#6279378:

I will be deleting snapshot01 in a week and a half, per https://phabricator.wikimedia.org/T245402#6514449

I suspect some or all of the Kafka hosts (it's required for changeprop to behave normally) need to be kept but I don't know which.

The situation of the memcached servers is amazingly telling of how deployment-prep is unmanaged, and we should really dedicate some resources to it, but also work better when we do stuff there.

The memcached servers are used primarily for memcached, and then for redis (mainstash) and redis (locking).

See below the usage matrix:

server	memcached	mainstash	locks
memc04	x	x	x
memc05	x	x	x
memc06		x
memc07		x
memc08	x

My proposal would be to move everything to memc06-08, and remove memc04/05 soon, but this will need to be scheduled and done by someone. In the meantime, all those servers are currently serving traffic.
