Hi,
a customer is asking me if there is a best practice to size AppSynch http servers.
We have a load balancer in front of two apache server with 4GB of ram and 4 CPU (we asked for 8 GB) but the customer thinks it's not enough.
Customar has 20.000 user that potential could connect to AppSync in the same two hours after a big update (ex. MS Office 2010 200MB of update) and is asking to me and my team how many web server he has to implement.
We are thinking about 4 or 6 have you got any similar experience?
