Hi,

I am wondering if DNN based websites can scale easily as user load increases which'd require that contents get served via multiple front end webservers and possibly multiple backend sql machines.

Also what is the biggest site (in terms of user load) which is DNN based and which makes use of multiple DB servers and multiple web servers. I'd assume this very site is pretty big but not really sure

Yes I did read a bit about 'web farm' support and 'multiple database support' but I am still not clear if they really mean what I am looking to get answers for. For example, if multiple db support mean you can make it run against mysql or ms sql that really doesn't mean you can have multiple DB servers of ms sql serving contents. It may very well mean both but this is what I really want to confirm.

thanks,

Actually, DNN can run against any database you want to write your own provider for, but it will run fine with multiple Database Servers in a cluster.  Same with a web farm front end.  It's also quite possible to do custom coding to match to your system even better.  As an ASP.NET app, DNN scales extremely well.

Not every module will behave properly in a webfarm.  It really depends on how the module was written - does it use Session, does it work with UNC file paths, etc.  Some of the limitations will depend on your specific webfarm configuration as each farm can have its own challenges.  Ultimately though you will need to test it.  If you are thinking of purchasing a module, you should ask the vendor if their module works in a farm and if you purchase it and it doesn't work how willing are they to help you resolve the issue or refund your money.  I would suggest that you do your research and speak directly to the module vendor as they will have the most information about which configurations they support and which they don't.
