The short version

  • Each has a real cost: Memcached no persistence at all: restart a node and its cache is gone, which every design must assume; 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: Memcached covers In-memory key-value cache, Nomad covers Container orchestration.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Memcached

  • No persistence at all: restart a node and its cache is gone, which every design must assume
  • No replication or failover, so losing a node loses that share of the cache
  • Only simple key-value, with none of the lists, sorted sets or streams Redis offers
  • Values are capped at 1MB by default, which surprises teams caching large documents

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
