I updated a new virtual cloud blog I started this week with a post describing how I approach the problem of maintaining active tomcat sessions within a "cloud" architecture of tcServer (tomcat 6.0) instances.
I tried to lay out, in excruciating detail, my thoughts on distributed membership and how I approached that particular sticky wicket. Non-multicast Tomcat Session Clustering with RabbitMQ: http://jbrisbin.wordpress.com/ The project is hosted on GitHub, though it is sorely lacking documentation on building and installing. I'm working on that. I've tried to make it as simple to use as possible, even though the process is not terribly straightforward on the back end. Some things I don't know yet but will need to include: how this system works under load; is it scalable (it would be a bummer to design a scalable solution and not have it scale...been there, done that, not interested in doing it again ;). etc... Concurrency might become an issue. As the number of workers increase, is the system stepping on its own toes trying to load user sessions? This is about as alpha and "it might not even build or work" as it gets. The ink's not even dry on it yet. I guess that's my way of saying: if you try it out and it doesn't work, please don't swear at me. ;) Patches welcome, of course...
