HashiCorp Nomad is an easy-to-use, flexible workload orchestrator that intelligently deploys and manages heterogeneous workloads (Containers, VMs, Windows, Linux, batch apps) using a single, unified workflow. It can drastically reduce costs by using bin packing to efficiently schedule jobs, which significantly improves infrastructure utilization.

In this solutions engineering hangout, Russ Parsloe shows seven different demos taking users from Nomad installation, to running and scaling your first jobs, to using Consul and Fabio to automate more steps, and concluding with a canary deployment.
