What is wrong with AMQP is an epic (read: way too long) rant about the standards sausage factory, specifically AMQP.
I skimmed, but I love this part:
In my view, the first problem is that AMQP has been positioned as an “Enterprise Technology”. What does this mean? I think the intention is that technology is like air travel, which is segmented into a cheap, sterile, tiresome, squashed experience for the ordinary jeans-and-sneakers proles, and an expensive, luxurious VIP experience for the high-value suits. You have ordinary prole technology, and then you have Enterprise Technology. AMQP has to be the very best, since it’s going to be used in banks and so on. You would not want your pension to be lost thanks to a missing transaction. AMQP users are VIPs, and intend to travel Business Class. Both customers and suppliers prefer the luxury route: it means bigger budgets, and more air miles.
Now this may make sense in air travel, but as far as I can see in the software world, the prole technology is generally better, faster, more secure, more robust, and above all, simpler. Proles have less money to spend, but most importantly, less money to waste.
