  • Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Contabo fully unmanaged infrastructure requires all setup and maintenance by customer
  • They diverge on capability: Cilium covers eBPF datapath, Contabo covers VPS Hosting.
  • Prices and features above were last checked on 30 August 2026.

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

Contabo

  • Fully unmanaged infrastructure requires all setup and maintenance by customer
  • No formal SLA with financial compensation for downtime violations

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.

Contabo: Does Contabo raise prices at renewal?

No. Unlike many hosting providers, Contabo does not increase renewal prices. The promotional price you get at sign-up is locked in for future renewals.

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