Different Use Cases Require Different Solutions

Solace focuses on enabling real-time connectivity and event-driven data movement across your enterprise. PubSub+ Platform is an event streaming, management, and monitoring platform that will give your organization everything it needs to design, deploy, and manage event-driven systems across cloud, on-premises, and IoT environments.

Apache Kafka, on the other hand, excels at event streaming for storage and log aggregation for analytics.

Here’s our take on how Solace stacks up vs Apache Kafka for various use cases:

Great Good Other
  • Not suitable for large scale 
  • Needs to be fronted by other MQTT brokers
  • Great sensor data consumption and command and control
  • Static routing between clouds
  • Poor reliability 
  • Complex remote client setup
  • Great multi-cloud dynamic event routing
  • No remote client setup required
  • Great IaaS services integration
  • Good throughput versus reliable performance
  • Limited exchange patterns 
  • Java and other community driven languages
  • Many uses not truly suited for Kafka batching
  • Great breadth of  languages, protocols, message exchange patterns
  • Advanced event mesh
  • Good CDC tools
  • Less flexible multi-site hybrid cloud solution
  • Great for bimodel development with hybrid cloud
Stream Processing
  • Core product use case
  • Messaging and streaming with good 3rd party stream processor APIs integrated
Low Latency
  • Batch architecture limits performance
  • Great core product use case
  • Great core product use case
  • Good for bimodel development with hybrid cloud
  • No individual message acknowledgement 

  • Individual message ack out of the box (i.e., Need to act upon a ticket purchase)

Feature Comparison Summary

APIs & Protocols​
  • Non-standard based JAVA API​:
    Others are created independently which leads to inconsistency,​ no backwards compatibility, no support​​
  • APIs for standard protocols: AMQP, JMS, MQTT, REST and WebSocket​
  • Open APIs: Apache Qpid and Eclipse Paho​
  • Only fast for non-secure communications​
  • High performance messaging for all QoS​
  • Faster than Kafka even with TLS enabled
  • Complex tiers and components leads to points of failure​ and places where messages can disappear
  • Highly Optimized WAN distribution including intelligent routing and streaming compression​
  • Relies on bridge layer to manage security​
  • Requires manual integration of LDAP/Radius with SASL
  • Easy to integrate with existing authorization systems​ and segregates client authentication and data movement into application domains
  • Limited scale, exact match subscriptions on flat topics​
  • Lack of fine-grained filtering makes it hard to overlay​ multi-zone hierarchy in hybrid/multi cloud systems
  • Enables sophisticated routing and filtering​​ with support for topic hierarchies, filters and wildcard subscriptions
Messaging Features​
  • Only supports pub/sub messaging
  • Supports all patterns and QoS:​ Pub/sub, request/reply, non-persistent, point-to point queues, replication across sites
  • Independent components for configuration, state coordination and inter-cluster communication​
  • Hard to achieve lossless multi-site disaster recovery
  • Broker holds config data and message state,​eliminating need for other components making it easy to deploy, run and scale
