From Zero to WOW! with HashiCorp Nomad

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.
