I plan to host Asterisk instances on AWS/EC2 servers. 
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.
How should I choose EC2 instance?
How many vCPU, RAM should be selected? I am assuming that server with ssd is required as all 500+ calls needs to be recorded.
