Confluent Is Now Part of IBM:
What It Means for Your Roadmap

Roadmap &
Pricing Questions

Any acquisition can change a product’s roadmap, pricing, and support priorities over time, and those decisions now rest with IBM. If that uncertainty matters to your team, it’s a reasonable factor to weigh when evaluating alternatives to Confluent.

Architecture &
Cost Considerations

Confluent is built on Kafka’s log-based design, which delivers full topic streams to each consumer, so consumers filter client-side and teams manage partitioning as topic counts grow — work that can add cost at scale. Solace’s broker-side filtering and predictable pricing are designed to reduce that overhead.

Solace vs
Confluent

Solace is focused exclusively on real-time event streaming — one mission, one platform, one team. For organizations that value an independent, single-focus vendor, that’s a meaningful difference when weighing a Confluent alternative.

What’s Holding Your Confluent Deployment Back?

Confluent Pricing at Scale

The Confluent Challenge

Per-partition and per-connector pricing can compound as usage grows. When many consumers read the same topic but use only part of the data, you can pay repeatedly to move bytes that aren’t acted on.

Impact

  • Operating costs can rise as usage grows
  • Schema Registry and connector licensing can add line items
  • Partition management can require added engineering effort as topic counts grow

The Solace Advantage

Predictable pricing. Broker-side filtering and push-based delivery mean consumers only receive events they need — no per-partition multiplier, no per-connector surprise.

Improvement Metric

Lower total cost of ownership in comparable deployments.

Lock-In Across Your Enterprise Stack

The Confluent Challenge

Confluent’s proprietary connectors and Schema Registry can create dependencies that influence the rest of your enterprise stack.

Impact

  • Potential pressure to consolidate around a single vendor over time
  • Reduced flexibility with cloud, observability, and tooling choices
  • Strategic flexibility can narrow over time

The Solace Advantage

Vendor-neutral by design. Solace treats every cloud, protocol, and ancillary technology as a first-class citizen. Your stack stays yours.

Improvement Metric

Zero proprietary connector dependencies. Runs identically on AWS, Azure, GCP, on-prem, and edge.

Managed Kafka with Proprietary Dependencies

The Confluent Challenge

Managed Kafka that also relies on proprietary components — Schema Registry, ksqlDB, premium connectors — alongside open-source Kafka. /p>

Impact

  • Open-source Kafka work can become tied to Confluent-specific features over time
  • Migration costs can grow over time
  • Open-source flexibility can narrow toward a single vendor

The Solace Advantage

Kafka-compatible without the lock-in. Solace runs alongside existing Kafka clusters via the Kafka Bridge — keep what works, reroute what doesn’t. Let Solace move the data, let Kafka remember.

Improvement Metric

Coexists with existing Kafka without rip-and-replace.

Limited Native Support for Agentic AI

The Confluent Challenge

Confluent’s topic and partition model is costly to reshape at runtime, so the many fine-grained, short-lived subscriptions of agentic AI workloads tend to drive topic sprawl and frequent consumer-group rebalancing.

Impact

  • Repartitioning can slow AI iteration
  • Agents may act on stale or partial data
  • Custom orchestration can consume engineering capacity

The Solace Advantage

Native Agent Mesh. Wildcard topic hierarchies handle dynamic AI subscriptions natively — agents subscribe at the broker, receive filtered events instantly, and tear down cleanly. /p>

Improvement Metric

Real-time fan-out to large numbers of dynamic subscribers.

Fan-Out Compute Overhead

The Confluent Challenge

Confluent filters on the client side rather than at the broker, so each consumer typically receives the full topic stream and discards what it doesn’t need.

Impact

  • A significant share of fan-out traffic can be data that’s discarded
  • Compute, network egress, and engineering costs can scale with that overhead
  • Cloud costs can grow faster than the value delivered

The Solace Advantage

Broker-side filtering. Topic wildcards mean consumers receive only the events that match their subscription — the wasted bytes are never sent.

Improvement Metric

Meaningfully less consumer-side compute on fan-out workloads.

Connecting Beyond Kafka Requires Adapters

The Confluent Challenge

Confluent uses the Kafka protocol, so MQTT, AMQP, JMS, and REST typically each need a separate connector or translation layer.

Impact

  • Additional connectors to license, monitor, and maintain
  • Added latency on each protocol hop
  • IoT, mobile, and legacy systems can sit outside the stream

The Solace Advantage

Native multi-protocol broker. The same event reaches a JMS consumer, an MQTT device, and an HTTP webhook without translation.

Improvement Metric

6+ protocols natively; zero translation middleware.

Multi-Cloud and Hybrid Streaming Complexity

The Confluent Challenge

Cluster linking and cross-region replication in Confluent can be operationally complex and resource-intensive.

Impact

  • Added operational effort to keep replication healthy
  • Outage exposure if links lag or fail
  • Edge and on-prem sites can be harder to integrate

The Solace Advantage

Dynamic event mesh. Events route across cloud, on-prem, and edge from a single control plane — self-healing topology, no replica lag to chase.

Improvement Metric

One mesh spans every environment, with new regions added quickly.

Why Enterprises Choose Solace Over Confluent

Kafka was built for appending logs. Confluent added a connector layer to enable streaming. Solace was built for moving data in real-time — and has added an integration layer to enable streaming. That architecture more closely matches the needs of 2026: efficient RAG pipelines, agentic AI, and operational real-time data.

And it’s all part of a proven platform with best-in-class support.
One platform, built by one team — focused entirely on real-time event streaming.

Event-Driven Architecture

Queue-based event mesh delivers efficiency that’s hard to achieve with a log-based structure.

Icon Price

Lower TCO

Predictable pricing, broker-side filtering, and push-based delivery reduce compute waste.

Solace Platfrom for Agentic AI

Built for Agentic AI

Dynamic wildcard subscriptions let AI agents subscribe to precise events in real time — without repartitioning. Native Agent Mesh orchestration.

Multi-Protocol

Connect legacy, cloud, and IoT without adapters thanks to support for AMQP, JMS, Kafka, MQTT, REST, and WebSocket.

Any Environment

Every cloud and technology treated as a first-class citizen — no proprietary lock-in. Cloud, hybrid, on-prem, edge — one platform.
