I have three physical machines and I am trying to run one of the machine in both client and server mode. I know this is weird but the load is not critical so wanted to have same machine to run in both server and client role. The machines are powerful enough to do that.
Does it mean that minimum nomad cluster requires minimum of 5 instances? 3 server + 2 clients? This gets quite pricey for just to start with. I probably didn’t include additional consul cluster. What are the risks of running just 2 servers?
For servers 4-8+ cores, 16-32 GB+ of memory, 40-80 GB+ of fast disk and significant network bandwidth. So far we are also struggling to find easy & manageable container orchestration just to start with.
i assume it’s also possible to run 3 machines, with nomad in both client+server mode on each to provide resiliency against downed machines on day 1, before scaling warrants a real cluster?
