In this slide, we presented to MaGIC Malaysia for entrepreneurs wanting to get an Asterisk business on cloud going. Here, we provide the most basic, lowest level method of having a HA on Microsoft Azure with FreePBX,
Components used with Azure's Ubuntu 14.04 image
1) Asterisk 11
2) FreePBX 2.11
4) Heartbeat - but without actually relying on Virtual IP since we use Azure Cloud to do the HA by exposing TCP5060
5) Use Azure's HA method to achieve HA by ensuring that whichever server that "listens" to port TCP5060 will have all the HA DNS name of Asterisk traffic redirected there.
