Agreed, network will be bottleneck even with ssd  on shared resource. For a 
stable env having a dedicated hosted server will be the best approach and 
cheaper too.

What's the status with Asterisk REST API?
Any experiences on performance,stability,documentation, caveats? Any

While bugs have crept up they haven't really been in the performance or 
stability area. It's mostly been features and making it a better 
experience for the users of ARI. Documentation wise the wiki[1] has a 
lot of great information including some example usage and a list of 
libraries. There's also a new asterisk-app-dev mailing list which is 
focused on applications built upon Asterisk.

As you've probably discovered, most of the API toolkits are half baked and 
poorly maintained.  The Java interface is not great for performance and is 
suffering from the above too.

This topic might step on troll territory (which  is best) so feel free to 
email me off list if you want more info.

Still a shared resource.  I don't see the benefit.

Even beyond the shared resource bit, with the kind of IO you are likely 
to be pushing, you will want a decent NAS with lots of spindles and 
fibre channel to your hosts.

Sure you see lots of posts about hosting asterisk and/or freeswitch 
on EC2.  I have done it myself and even have some clients doing it 
now *for proof of concept*.   I've never heard of anyone using it for 
the kind of load you are talking about.  I'm assuming with such a

Amazon instances are shared resources.  I wouldn't want to count on 
timing or disk throughput, and you can't just ask them to do "ssd" - its 
a virtual machine!  500 simultaneous recordings is a hefty load, and I 
would want to know that the underlying hardware is dedicated to the task.


Sure you see lots of posts about hosting asterisk and/or freeswitch on 
EC2.  I have done it myself and even have some clients doing it now *for 
proof of concept*.   I've never heard of anyone using it for the kind of 
load you are talking about.  I'm assuming with such a giant load you are 
making a decent profit. Buy some hefty hardware and do the architecture 
properly.  You can rent half a rack at lots of high end datacenters for 
less than $1000/month.
