Minibar London, May 25th

Just had a reminder e-mail from Christian that the next Minibar is coming up, this time with a focus on geolocation and mapping services.

[ upcoming.org entry ]

This fits in with my interest in services like Plazes and Dopplr, geotagging, and cool gadgets. I’ll definitely be making an effort to make it.

Dale should probably come along, too 🙂

Amazon SQS – some of us queue already…

I became aware of Amazon Simple Queue Service early last year. I haven’t had much of a chance to do anything with it beyond playing with demos. I thought I’d written about it, but can’t find the previous entry I believed I’d posted!

Over on the Amazon Web Services blog, there’s a very good post describing message queueing, and why asynchronous communication is a good thing. Choice snippet:

Queuing allows and encourages applications to become truly service-oriented. You will be automatically making the right architecture decision of making your applications service-oriented and independent to others.

Not only that, but some people seem to feel that the platform that Amazon have been building is pretty impressive. I don’t disagree.

Time for another look, I think. I’ve been dealing with message-oriented middleware for the best part of 7 years now, primarily with WebSphere MQ, and I’ve looked at a couple of the alternatives… the main issue I have with SQS in particular is the use of HTTP as the transport, but that makes some sense in the WOA view of the world. I’ll have to dig deeper.
