Hi Emrah , 1. You can use the AWS LBR with any other VPS you like - EC2 is not a must. Actually, I'm planning to have the first FS on each region with a regular VPS (cost effective for full month) and the 2nd FS with EC2 (I can turn on/off per load). 2. Yes, I'm using Mysql as my centralized DB. 3. In my centralized DB I've defined a customized LOCATION table which basically records username/FSserver pairs (and other info as well). When a sip client REGISTER with its neareast FS (LBR), then the FS update the centralized LOCATION table with its fs_id and sip_id. When the sip client disconnect from that FS (look for reg status) then the FS updates the LOCATION as well (clear/update record).
