The big advantage I like, is the ability to have identical production and development environments, without having to continuously run the development environment. When writing up how to install DAHDI on an Asterisk EC2 instance, I went through several instances, I could bring up an instance in minutes, use it for 10 or 15 minutes and then throw it away. I could do something similar with VMware ESX attached to a SAN, but it is much more capital intensive, even with leasing. For a single box, EC2 probably isn't going to be cheaper. But if you have a dynamic environment; need web, asterisk, and database servers; scaleable storage; and off-site backup, EC2 starts getting more cost effective. Storing Asterisk realtime data in Amazon's SimpleDB and voicemail in S3, would make for a very interesting and scalable solution. -- Eric Chamberlain, Founder RF.com - http://RF.com/ _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
