Where each one falls short

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

Azure DevOps

  • First 5 users free applies to Basic plan only; Test Plans users are not included in free tier
  • Storage pricing increases per-GiB cost as volumes grow, with no volume discount threshold below $0.25

NATS

  • Core NATS has no persistence at all, so messages are lost if no subscriber is listening
  • JetStream adds the durability but also the operational complexity NATS is chosen to avoid
  • A much smaller ecosystem than Kafka or RabbitMQ, with fewer connectors and integrations
  • Fewer people know it, so hiring and existing organisational knowledge favour the alternatives
