Hello,

(Mod: Please move it to appropriate forum, if this is not correct forum for this question)
I need some suggestions regarding server technical setup for Ethereum Wallet for new ICO. Obviously this is serious job of infrastructure and security engineer, but as a start, I am looking for some generic idea. Each user will have own login details to their control panel. They can always login to their control panel and see their invested Eth.
If it has to be planned on AWS Windows instance, what kind of instance can be picked (General Purpose vs Compute Optimized vs GPU Instances  vs Memory Optimized vs Storage Optimized) ?
I am feeling that network performance should be high, but how to determine the network performance ?
How redundancy will play here ?
How (large amount of) traffic will be handled, if many users will hit website ?

It would be great help, if somebody can suggest or have some discussion on this.

Thanks in advance
