Messages in subject-based publish/subscribe systems are sent to subscribers based on the subject that describes the contents of the message.

What is the difference between Kafka and JMS?

Kafka and JMS are designed for different purposes. Kafka is a distributed streaming platform that offers high horizontal scalability. Also, it provides high throughput and that’s why it’s used for real-time data processing. JMS is a general-purpose messaging solution that supports various messaging protocols.
