HashiCorp's Game of Life
summary
Implements Conway’s Game of Life using Nomad, Consul, Terraform and Go with each cell as its own process and rules applied locally. Prototype floods Nomad with API calls and overwhelms Consul DNS causing CPU and “server misbehaving” errors; final design replaces thousands of job creations with a single Nomad job that spawns groups, uses 300 cells per node, relies on Consul DNS over UDP tick tock for service discovery, and scales to over 2,000 jobs while reliably running glider gun demos.
