Nomad is a cluster manager, designed for both long lived services and short lived batch processing workloads. Developers use a declarative job specification to submit work, and Nomad ensures constraints are satisfied and resource utilization is optimized by efficient task packing. Nomad supports all major operating systems and virtualized, containerized, or standalone applications.

The key features of Nomad are:

• Docker Support: Jobs can specify tasks which are Docker containers. Nomad will automatically run the containers on clients which have Docker installed, scale up and down based on the number of instances requested, and automatically recover from failures.

• Operationally Simple: Nomad runs as a single binary that can be either a client or server, and is completely self contained. Nomad does not require any external services for storage or coordination. This means Nomad combines the features of a resource manager and scheduler in a single system.

• Multi-Datacenter and Multi-Region Aware: Nomad is designed to be a global-scale scheduler. Multiple datacenters can be managed as part of a larger region, and jobs can be scheduled across datacenters if requested. Multiple regions join together and federate jobs making it easy to run jobs anywhere.

• Flexible Workloads: Nomad has extensible support for task drivers, allowing it to run containerized, virtualized, and standalone applications. Users can easily start Docker containers, VMs, or application runtimes like Java. Nomad supports Linux, Windows, BSD, and OSX, providing the flexibility to run any workload.

• Built for Scale: Nomad was designed from the ground up to support global scale infrastructure. Nomad is distributed and highly available, using both leader election and state replication to provide availability in the face of failures. Nomad is optimistically concurrent, enabling all servers to participate in scheduling decisions which increases the total throughput and reduces latency to support demanding workloads. Nomad has been proven to scale to cluster sizes that exceed 10k nodes in real-world production environments.

• HashiCorp Ecosystem: HashiCorp Ecosystem: Nomad integrates with the entire HashiCorp ecosystem of tools. Like all HashiCorp tools, Nomad follows the UNIX design philosophy of doing something specific and doing it well. Nomad integrates with Terraform, Consul, and Vault for provisioning, service discovery, and secrets management.
