But, things have just changed. WebSphere MQ has now extended its reach beyond servers and desktops over to even smaller devices which are getting more and more ubiquitous by the day. Mobile phones, PDAs and even little circuits with sensors can now directly deal with WebSphere MQ.
How is this possible ?
WebSphere MQ Telemetry makes this possible. WebSphere MQ now comes equipped with a listener that caters to the MQTT protocol. MQTT is a lightweight protocol that is designed for slow and flaky networks. MQ also comes with C, OSGI and J2ME APIs for the clients to talk to a queue manager.
Earlier, industries which required little pieces of electronic sensory equipment to be integrated with their messaging infrastructure had to go through other links in the chain like Microbroker or implement custom code to send data to MQ. With MQTT, such equipment can talk directly to MQ queue managers.
Take the case of courier and shipping industry. With low cost, ubiquitous mobile devices, the delivery guy can update the status of an order instantly without going back to the office.
Or take the case of your electricity meter. Monthly readings can be directly transmitted to the electricity board without manual intervention.
Take the case of city taxis or pizza delivery. The list is just endless and so are the possibilities.
In summary, MQ Telemetry serves to reduce a crucial link in the chain connecting on-the-field devices to messaging servers.
