As part of my constant learning curve into what you can do to make apps scale better, I am currently trying to get a direction to go with queuing, i.e. job queuing or workload processing whichever phrase you like.
In the distant past I used IBM MQ/Series - it worked for a financial app but quite heavy if I remember.
I know of MSMQ, and I have also heard of quite a few others.
But first, here is my context
I have a C#/.NET back-end web app which serves data etc to a Javascript (mostly jQuery etc) front-end via AJAX calls etc. I have a situation where a certain action involves uploading some files, setting up a few record entries in the database, emailing some users etc. So of course I don't want to make this process "online"/"real-time" due to the possible time delay and I am sure the overheads on the webserver/database etc.
So given the type of "messages" that I need to queue and process, what would be (I shouldn't just say easy here I guess!) a good start point? should I run with MSMQ and/or the SQL 2008 service broker stuff, or something like ZeroMQ - or should I simply create my own lightweight workload queue service?
I realise again without seeing the full picture it is hard to make full recommendations, however any start points gratefully received!
