hi whats the professional way to do server load balancing (or clustering) over long distances?
Heres what I want to do: When our main server goes down we want to switch over to our backup server at our homes but we want to do this instantly and transparently to the user. Web, mail and ftp. My solution for mail of course was to do multiple MX entries. Thats the easy part. But for web? No, I wont go with round-robinning DNS A entries--all traffic should go to the main server at all times but will fallback to our other servers when thats down. Playing around with TTL or any other DNS trick wont do either. Either its intantaneous or I wont do it. I've already looked at linux virtual server but that will only work on a cluster on the same site. I've tried to read up BGP but I cannot understand it--that technology will be beyond me. Just want to know how the pro's do it. If it can't be done with simple routers i understand. JUst give me an idea how its done, so I can explain better why or why not I cant do it. Or perhaps give me a direction on which way to research. thanks in advance, jondz -- Hagibis Fan <[EMAIL PROTECTED]> -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
