Pub/sub Messaging


Pub/sub messaging is a messaging pattern where senders of messages, called publishers, do not send messages directly to specific receivers, called subscribers. Instead, messages are sent to a central message broker, which then distributes the messages to all subscribers that have expressed interest in receiving them. This decoupling of publishers and subscribers allows for greater scalability and flexibility in distributed systems, as publishers and subscribers do not need to know about each other's existence. Pub/sub messaging is commonly used in real-time data processing, event-driven architectures, and IoT applications.
