How is Nomad different from Kubernetes?
Nomad is simpler to operate (single binary vs complex Kubernetes stack), handles non-containerized workloads natively, and integrates with the HashiCorp ecosystem. Kubernetes has a larger ecosystem and is more widely adopted, but Nomad offers lower operational complexity for mixed workloads.
Is Nomad free to use?
Nomad core is free and open source. Enterprise features like namespace quotas, audit logging, and multi-region federation require a HashiCorp Enterprise license. Most small to medium deployments work fine with the free version.
Can Nomad replace Kubernetes?
Yes, for many use cases. Nomad can run containerized microservices just like Kubernetes, but with simpler operations. Choose Nomad for operational simplicity and mixed workloads. Choose Kubernetes for the larger ecosystem and if your team already knows it.
What companies use Nomad in production?
Major companies using Nomad include Cloudflare, Roblox, CircleCI, Trivago, and Deluxe. These deployments range from thousands to millions of containers, proving Nomad scales to enterprise requirements.
Does Nomad work with Docker?
Yes, Nomad has native Docker support and also supports Podman, containerd, and other container runtimes. You can also run non-containerized binaries and scripts directly, which Kubernetes cannot do natively.
How does Nomad integrate with Consul?
Nomad integrates natively with Consul for service discovery and service mesh. Jobs can automatically register with Consul, enabling other services to discover them. Consul Connect provides secure service-to-service communication.
