Oh and joinmastodon.org/ is a fantastic resource for learning about Mastodon. The short version is that it's Twitter but hosted like email: you can connect with anybody even though there are lots of distinct hosts.

Watching @HashiCorp Nomad manage 10k servers is... pretty boring actually? The 3 Nomad servers were t2.mediums as were 7 of the client nodes. The other 10k clients are the real Nomad client node code but packed 100 per container across 100 containers on the 7 real nodes.

The point of the exercise was to test things like Nomad's heartbeat scaling and failover. Sure enough after I kill -9'd the leader server, another was elected leader, and no client nodes were lost!

Word of warning if you try this at home: @googlechrome does *not* like trying to draw 10k boxes. 7k was fine, but somewhere between 7k-10k client nodes the topoviz page broke Chrome in the Nomad UI.

Are there good golang libraries which does shard management for distributed stateful services? In the past built this on top of Hashicorp’s raft and member-list libraries, but that was a long time back. I am hoping there are libraries now which does this out of the box.

Can't wait to see what @erikveld is up to at @HashiConf next week! Looks like he's going to take us on a Minecraft tour of Hashikea and assemble Nømad and Cønsul. 📦👀

I know a lot of folks have bounced off Nomad when they discovered they also had to manage a Consul cluster for even the most basic use cases... No more! Check out this post explaining how you can get started with ✨just Nomad✨ now. 👇
