What is the difference between Kafka and ActiveMQ?

Kafka is based on a publish-subscribe messaging model, where messages are written to topics and subscribers can consume messages from those topics. It is designed for high-throughput, fault-tolerant, and distributed streaming scenarios. ActiveMQ, on the other hand, supports multiple messaging models, including point-to-point (queues) and publish-subscribe (topics). It provides more flexibility in choosing the messaging model based on application requirements.
