The short version

  • Only Confluent Cloud has a free tier, so it costs nothing to try first.
  • Each has a real cost: Confluent Cloud requires understanding of eCKU (Elastic Confluent Unit) billing; IBM MQ virtual Processor Core licensing is capacity-based, so an over-provisioned server is charged for cores the queue manager never uses, and consumption ratios differ between MQ and MQ Advanced.
  • 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.

Confluent Cloud

  • Requires understanding of eCKU (Elastic Confluent Unit) billing
  • Data in/egress costs add $0.014-$0.050 per GB
  • Storage costs of $0.03-$0.08 per GB-month
  • Minimum commitment recommended for cost optimization

IBM MQ

  • Virtual Processor Core licensing is capacity-based, so an over-provisioned server is charged for cores the queue manager never uses, and consumption ratios differ between MQ and MQ Advanced.
  • Container licensing requires Kubernetes with the IBM License Service, so Podman or plain Docker deployments cannot use the optimised metric and pay materially more.
  • Distributed and z/OS platforms use different licensing models, and organisations running both routinely misapply one to the other, which surfaces as exposure at audit.
  • Operating MQ needs specialist skills that are increasingly scarce, and the pool of engineers who understand channel and queue manager administration is shrinking with every retirement.
  • IBM’s acquisition of Confluent in March 2026 puts MQ and Kafka under one vendor, which resolves the integration story but removes the competitive tension that kept renewal negotiations honest.

Answered from the vendors’ own pages

Confluent Cloud: How much does Confluent Cloud cost?

Confluent Cloud pricing starts free on Basic tier with $0.14 per eCKU-hour, Standard at $0.75 per eCKU-hour (~$385/month base), Enterprise at $1.75-$2.25 per eCKU-hour (~$895/month base), and Freight specialty tier at $2.25 per eCKU-hour (~$2300/month).

Source
IBM MQ: How is IBM MQ licensed?

By Virtual Processor Core subscription, around 312 US dollars per VPC per month for MQ and 583 for MQ Advanced, minimum one year.

Confluent Cloud: Is there a free tier for Confluent Cloud?

Yes, the Basic tier is free with one eCKU credit included. Additional usage is billed at $0.14 per eCKU-hour, plus data transfer and storage fees apply.

Source
IBM MQ: Should we replace MQ with Kafka?

Only if you actually need a replayable log. MQ is a transactional queue; replacing it with Kafka usually means rebuilding transactional semantics in application code.

Confluent Cloud: What additional fees does Confluent Cloud charge?

Beyond eCKU hours, Confluent charges data in/egress at $0.014-$0.050 per GB and storage at $0.03-$0.08 per GB-month. Costs vary by tier and region.

Source
IBM MQ: What does MQ Advanced add?

Advanced Message Security, Managed File Transfer, MQTT telemetry and quorum-based high availability.

Confluent Cloud: Does Confluent offer discounts for higher usage?

Yes, volume discounts are negotiated upfront based on annual consumption estimates. Annual commitments allow flexible cross-product allocation with guaranteed cost savings.

Source
IBM MQ: Does container deployment change the cost?

Yes. Optimised container licensing needs Kubernetes with the IBM License Service; Podman or Docker deployments do not qualify.
