Has anyone implemented MQ listener in Pega cloud? I have gone through the below link it says pega cloud support MQ but Service-MQ and other MQ rules are deprecated. Please let me know if anyone succeeded to connect to mq following the steps in the link from Pega cloud.
I can't speak to exact number of clients using Connect-MQ. However, what you're looking to do is not uncommon. You have services on premises that need to be used by your application that help drive your business processing. In your specific case you have a MQ Server on prem with queues you would like PRPC to put messages to. No different than SOAP services or REST services being on prem and we see Connect-SOAP and Connect-REST being used a lot more than say Connect-MQ.
The PRPC application has to be able to connect to the service. For this to work your network team would work with our Pega Cloud team and get the connection between your PegaCloud instances and your on prem services defined. This is usually done with a a secured, encrypted VPN connection.
