Attached a picture of the QOTO swarm's resources for those who are curious.

Some interesting facts about the #QOTO cluster for those who are curious:

* Runs as a docker swarm, so easily scales as needed and services can move between computers in the cluster.
* Runs on a 7 computer cluster.
* Utilizes only about 5% at most of its CPU potential
* CPU has burst capability, so can go well beyond 100% for momentary high loads.
*Utilizes 33% of the memory (this includes caching). Almost all of the memory is from Gitlab.
* Requires half a terrabyte of on-disk size, with an additional 2 TB for used currently as shared disks.
* Supports 12 different services right now: fediverse-bots, discourse, wikijs, funkwhale, gitlab, 5-node load balancer, nextcloud, peertube, piwig, qoto-mastodon groups server, and two different monitoring tools.
* These 12 services run as 60 different interconnected docker containers spread across the cluster.

As for costs... the last year the total cost to run QOTO was **11,384.43$**. However I recently paid to reserve the instances instead of spot instances. So I expect the next year to be about 25% cheaper.

A 104 year old book I just added to my collection. It is still amazingly relevant too in the modern era.

In case anyone is curious about a sneak peek for whats next on QOTO, I am currently setting up a Matrix chat server with full bridging (so not only can you join chats on other matrix servers but you can also join them on other protocols like IRC and XMPP)... I will also most likely create a seperate XMPP server for those who want it.

Woa, all data across all QOTO services is approaching 10 TB! damn... luckily we have nearly infinite storage space.
