[asterisk-users] Asterisk on EC2 cloud computing - price assumptions - your brain needed

[John Todd]

I've been involved with getting better data for running Asterisk on  
the Amazon EC2 cloud computing system.  Here are some calculations  
I've made on costs based on current published prices on Amazon's  
system.  Feel free to tell me that I'm wrong with these calculations -  
but be specific if you find any problems, as I suspect others may glom  
onto these figures as gospel and I'd hate to have the wrong data in  
there.

The net of my calculations is that a small instance of 20 users in a  
standard office environment would cost about $75 per month, which when  
compared to running a server in-house works out to be (raw cost, not  
including admin time and not discounting out-of-office bandwidth) only  
$38.56 more.  Very interesting.
