A decent report on the state of the ESB market and the players in it. This is a good follow-up to some on-going discussions on the ESB versus XML appliances and content switches/smart routers. Scott Mark posted some thoughts on it which was followed up with a posting from Todd Biske. I think you will see from the report that Anne Thomas Manes over at Burton is an advocate of the XML appliance. My company is a client of the Burton group. Anne came and spoke with us about this and other SOA related topics earlier this year. The XML appliance was discussed a lot.
I'm still undecided on the appliance concept. You can see my thoughts over on Scott Mark's blog. Still it is becoming interesting and probably worth a look. It's now on my radar which is the first step to more serious research.
