Is Cilium or Nomad better?

Neither clearly leads. Cilium starts at Free and Nomad at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Cilium or Nomad?

Cilium starts at Free and Nomad at Free.

Does Cilium or Nomad run on more platforms?

Cilium runs on Kubernetes, Linux. Nomad runs on Linux, Windows, Mac, Cloud.

Can I use Cilium for free?

Both have a free tier, so you can try either at no cost before committing.

What is Cilium best used for?

Cilium is most often used for kubernetes networking at a scale where iptables-based cni performance degrades, network policy expressed on workload identity rather than fragile ip rules, seeing which services actually talk to each other, and what policy is dropping. Of those, kubernetes networking at a scale where iptables-based cni performance degrades and network policy expressed on workload identity rather than fragile ip rules are not what Nomad is typically brought in for.

What can Cilium do that Nomad cannot?

Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. Nomad covers Container orchestration, Job scheduling, Multi-cloud support, Auto-scaling.

The short version

Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Nomad nomad 1.7.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
They diverge on capability: Cilium covers eBPF datapath, Nomad covers Container orchestration.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cilium

Requires a recent Linux kernel, which rules out older distributions and some managed environments
eBPF is genuinely hard to debug when it misbehaves, and the skill is rare on most teams
Broad scope — CNI, policy, mesh, observability — means the learning curve covers several domains at once

Nomad

Nomad 1.7.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
The Additional Use Grant forbids offering Nomad to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions
Each version converts to MPL 2.0 only four years after that version is published
Resource quotas, Sentinel policies and audit logging sit in a Governance and Policy add-on module that is separate from the Enterprise base platform package
Multi-region deployments, multiple Vault namespaces and Nomad Autopilot advanced server management require Nomad Enterprise

Answered from the vendors’ own pages

Cilium: Is Cilium free?

Yes, open source and CNCF-graduated. Isovalent sells an enterprise distribution and support.

Nomad: Is HashiCorp Nomad free?

HashiCorp Nomad is open source and free to use. Commercial enterprise support and hosting options may be available through HashiCorp, but the core product is free.

Source

Cilium: What does eBPF change?

It lets Cilium run packet-processing programs inside the kernel instead of relying on iptables rule chains, which behave poorly as the number of services grows.

Nomad: Does HashiCorp Nomad have a pricing model?

Nomad is open source software with no published pricing tiers. HashiCorp offers commercial hosting and support for their products on a usage-based or custom pricing model, but Nomad itself is free to download and deploy.

Source

Cilium: Does Cilium replace a service mesh?

It can cover much of what a mesh does without sidecars, though full mesh feature sets still favour Istio or Linkerd.

Nomad: What is HashiCorp's pricing model for enterprise Nomad?

HashiCorp offers flexible pricing for enterprise Nomad support including pay-as-you-go (PAYG) billing with no long-term commitment, flex plans with preferred pricing, and enterprise self-managed plans. Contact HashiCorp sales for custom quotes.
