Nomad, orchestration made in HashiCorp
summary
A live demo shows HashiCorp Nomad used for orchestration: a cluster of 3 servers and 3 clients is provisioned with Terraform on Google Cloud, integrated with Consul for service discovery and running Docker containers. A Nomad job deploys Nginx frontend and Mongo backend groups, Nomad schedules three allocations, then a second datacenter on OVH is joined via Consul with a constraint forcing the DB there, and finally a US region is added—resulting in two regions and multiple datacenters in about thirty minutes; Nomad is presented as a single, simple binary.
