The short version

  • Each has a real cost: Eclipse Mosquitto there is no clustering: Mosquitto is a single process, so high availability means building your own failover and accepting session loss on switchover.; 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: Eclipse Mosquitto covers MQTT 5.0 support, Nomad covers Container orchestration.

Where each one falls short

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

Eclipse Mosquitto

  • There is no clustering: Mosquitto is a single process, so high availability means building your own failover and accepting session loss on switchover.
  • Persistence is a local file rather than a replicated store, so a disk failure or an unclean shutdown can lose retained messages and queued QoS traffic.
  • Practical capacity is a few thousand concurrent clients on typical hardware, so a growing device fleet eventually forces a migration to a clustered broker.
  • The Eclipse Public Licence is weak copyleft rather than permissive, which some legal teams treat as a blocker when embedding the broker in a shipped commercial product.
  • There is no commercial support to buy from the project, so production incidents rely on community mailing lists or on paying a third party who happens to know the codebase.

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
