Nomad
Nomad is a distributed workload orchestrator and infrastructure automation platform designed to manage the lifecycle of applications across large-scale, heterogeneous environments. It functions as a multi-cloud orchestration engine, providing a unified control plane to deploy, scale, and govern containers, virtual machines, and legacy applications. By utilizing declarative job specifications, the system ensures infrastructure convergence and maintains the desired state across distributed data centers and geographic regions.
The platform distinguishes itself through a flexible, plugin-based architecture that supports diverse execution drivers and specialized hardware, such as GPUs and FPGAs. It employs a hierarchical regional federation model, allowing organizations to manage independent clusters as a cohesive system while enforcing fine-grained security policies, resource quotas, and multi-tenancy through namespace segmentation. Its scheduling engine is built on a strongly consistent consensus protocol, ensuring high availability and fault tolerance even across complex, multi-cloud topologies.
Beyond core orchestration, the system provides comprehensive infrastructure governance, including integrated service discovery, secret management, and policy-as-code enforcement. It handles the full operational lifecycle of cluster nodes, from automated bootstrapping and health monitoring to rolling version upgrades and capacity scaling. The platform also offers deep observability through system metrics, audit logging, and reactive query mechanisms to maintain operational visibility.
Nomad is distributed as a single binary, supporting deployment patterns ranging from lightweight local development environments to massive, multi-region production clusters.
