IBM MQ

IBM MQ is an enterprise messaging system that enables different applications and systems to communicate reliably and securely by exchanging messages. It acts as a messaging queue, storing messages until the receiving application is ready to process them, ensuring smooth data flow even if systems operate at different speeds or are temporarily unavailable. Think of it as a digital post office that guarantees messages are delivered accurately and in order, facilitating coordination and integration across complex IT environments without requiring direct real-time connections.
