Where each one falls short

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

TIBCO Enterprise Message Service

  • The 2026 roadmap is oriented to modernising existing estates rather than winning new deployments, so a greenfield buyer is choosing a product its vendor is not investing in for growth.
  • Nothing is published on price, licensing is per server or per core, and renewal pricing across the Cloud Software Group portfolio has risen sharply since the 2022 Citrix and TIBCO combination.
  • It is a JMS broker, not a durable event log, so replay, stream reprocessing and long retention patterns require Kafka alongside it rather than instead of it.
  • Skills are concentrated in a contractor market that is ageing, and hiring engineers who want to work on EMS is materially harder than hiring for Kafka.
  • Deep integration with the rest of the TIBCO stack, particularly BusinessWorks, makes partial migration difficult; teams commonly find that leaving EMS means replacing several products at once.

Zilliz

  • Pricing structure not publicly disclosed, requires sales contact
  • Operational complexity for self-hosted Milvus deployments
  • Learning curve for those unfamiliar with vector databases
  • Limited built-in analytics compared to some alternatives
