IBM MQ vs MQTT: What are the differences?
Developers describe IBM MQ as "Enterprise-grade messaging middleware". It is a messaging middleware that simplifies and accelerates the integration of diverse applications and business data across multiple platforms. It offers proven, enterprise-grade messaging capabilities that skillfully and safely move information. On the other hand, MQTT is detailed as "A machine-to-machine Internet of Things connectivity protocol". It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.
IBM MQ and MQTT can be primarily classified as "Message Queue" tools.
