The short version

  • Only Solace PubSub+ has a free tier, so it costs nothing to try first.
  • Each has a real cost: OVHcloud public Cloud pricing table lists a scheduled price change with a column labeled Price on April 1, 2026, showing current rates are promotional and set to change on that date; Solace PubSub+ no pricing is published at any tier, so evaluation requires a sales engagement before you can even judge whether it is in budget, and broker tier sizing determines cost in ways buyers frequently get wrong.
  • They diverge on capability: OVHcloud covers Public Cloud, Solace PubSub+ covers Multi-protocol broker.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

OVHcloud

  • Public Cloud pricing table lists a scheduled price change with a column labeled Price on April 1, 2026, showing current rates are promotional and set to change on that date
  • Free network traffic and free Object Storage API calls exclude the Asia-Pacific region

Solace PubSub+

  • No pricing is published at any tier, so evaluation requires a sales engagement before you can even judge whether it is in budget, and broker tier sizing determines cost in ways buyers frequently get wrong.
  • The free Standard edition has hard capacity and support limits, which makes it useful for development but means any real deployment triggers a commercial negotiation.
  • The proprietary SMF protocol gives the best performance and feature coverage, so teams that lean on it acquire real switching costs even though open protocols are supported.
  • Operating a self-managed high availability broker pair with disaster recovery is a specialist task, and Solace expertise is scarce in the hiring market compared with Kafka skills.
  • Event Portal and Mission Control are licensed as part of platform packages, so the governance tooling that makes an event mesh manageable is not simply included with the broker.
