That’s basically what put me off trying nomad. Nit just the minimum number, but also their stated hardware requirements. From their documentation:

Nomad servers may need to be run on large machine instances. We suggest having between 4-8+ cores, 16-32 GB+ of memory, 40-80 GB+ of fast disk and significant network bandwidth

Basically the cost if the Nomad masters would be much greater than the cost of what would run my actual applications. That’s a non-starter for me.

> You I think you could be fine with 3 of the smallest machine types.

Maybe, but if that’s their official stance, it would make me very nervous to run a production system with lower spec machines.
