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

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.<br>
<br>
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.<br>

<br>
Are you aware of any challenges of hosting it on AWS? It
will help me to work out alternate plan. Is there any
recommendation? Should I split it to multiple instances
and balance traffic across multiple small server
instances? I can use Kamailio to balance traffic.<br>
<br>
I see many posts referring to AWS deployment. Please
help me to choose AWS server instance.<br>

Why use Amazon? With that kind of load I would want
dedicated servers. Call Rackspace or Softlayer.<br>

<br>
I plan to host Asterisk instances on AWS/EC2 servers. <br>
Requirement is to run asterisk instance with transcoding
(g.729 + g.711) and full recording. Number of concurrent
calls expected are 500+. 2 instances will be configured
for 100% redundancy. Heart beat will be used to
determine active instance.<br>
How should I choose EC2 instance?<br>
How many vCPU, RAM should be selected? I am assuming
that server with ssd is required as all 500+ calls needs
to be recorded.<br>
<br>
