Polling duplex does not scale... what's the alternative?
- by user80855
Our tests showed that the polling duplex binding simply does not scale and can not be used on a service within a web-farm or even a web garden. We have looked at TCP/IP sockets for a client push method, but the firewall issue is does allow us to use sockets.
I was wondering what is the alternative "free" solution to this problem? allowing us to scale and allowing us to push data to client...
I have also tried the solution in this article http://tomasz.janczuk.org/2009/09/scale-out-of-silverlight-http-polling.html but at the end, there was too much polling on a database, and performance was affected.
Our Silverlight application need a pub/sub design, but it needs to be reliable and scalable... any ideas?
