Oh sorry, I wasn't thinking.  Yes, the settings in your one web.config will be what's deployed to all instances.   So the sessionEncryptionKey only needs to be set once.]]> Wed, 30 Mar 2011 14:26:46 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=2593&PID=10325#10325 Azure Scaling : Hi Kim, this sounds very good... http://www.ideablade.com/forum/forum_posts.asp?TID=2593&PID=10324#10324 Author: Andrew

Hi Kim,
 
this sounds very good for the Azure-future.
Data Center license together with DevForce Universal is already purchased.
I have set the sessionEncryptionKey long time before to a certain value within the serversettings.
Am I right that this value will be used for every instance then?
 
Thanks
Andrew

DevForce is actually unaware (for the most part) that the application is load balanced.  It "scales" in that the EntityServers will be running on as many instances as you've got.  None of the EntityServers knows about the others.

An EntityServer is almost stateless, so the memory requirements should not be high.  I say "almost", because there is metadata loaded, and user "session" information, but all of this will be recreated as needed on a new instance.
 
The only known issue is that you can't use Push with Azure, because it's not stateless.
 
Also remember that you must have a Data Center license, and to set the serverSettings sessionEncryptionKey to the same value on every instance.

I'm interested in any experience regarding the azure deployment.
 
The goal is to host a multi tenant Devforce-Silverlight-Application with several SQL-Azure databases behind.
The databases have a range from 200 MB up to 6 GB.
 
 
1. Does DevForce scale within Azure when I add new instances?
2. Is there a recommended or minimum type of instance maybe regarding to the memory?
3. Are there any other known issues that I have to take within Azure when hosting the Devforce-Silverlight-Application?
 
Thank you
