RE: Witango-Talk: Round Robin DNS

[Robert Shubert]

There is a server guide on www.witango.com, and the SP1 docs from Tango2000 also covered it in detail (although the terms and names might be outdated now). It is also good to use the list and I offer consulting for complex windows installations as part of my reseller/consultant services.   It is not required to have professional for load balancing….   Load balancing can be done with 1 Professional license, by installing 2-4 services on one machine.   Load balancing can be done with 2 Standard licenses, by installing 1 service on each of two machines.   The former helps deal better with high volume, by further balancing the threads, it is also the only way you can take advantage of multiple CPU machines (including HT).   The later protects you from hardware failures as well as adding CPU power.   It is only required to have a professional license if you want to access more than one CPU on your server with Witango, or if you wish to provide hosting services.   Hope that helps.   Robert   -----Original Message----- From: Rich [mailto:[EMAIL PROTECTED] Sent: Friday, June 11, 2004 10:56 AM To: [EMAIL PROTECTED] Subject: RE: Witango-Talk: Round Robin DNS   Robert, Is there any aids in setting up load balancing between servers? Also do I professional for this?   rich -----Original Message----- From: Robert Shubert [mailto:[EMAIL PROTECTED] Sent: Friday, June 11, 2004 10:51 AM To: [EMAIL PROTECTED] Subject: RE: Witango-Talk: Round Robin DNS At www.footballfanatics.com we used one "gateway" machine, which actually ran WiTango. It would look at a table of available machines and redirect the user to "www1." or "www2." etc.   This is called "Sticky-IP" technique. The disadvantage is that you can't change servers mid-session. So if you're at the site and the box goes down to have to come back to the site manually and get redirected to an active machine.   The advantage of using WiTango to do it than round robin DNS is that we made outselves a nice little web interface to manage the server pool and we didn't have to depend on any third-party DNS solutions.   There is a way to set WiTango up with "high availability" mode, meaning any one machine failure is transparent and session variables are transportable between servers, but I have no idea how to do it. - James.

There is a Witango load balancing system, true. However, while it does handle instantaneous failover from a downed server, it does not handle session maintenance. This means that a user would have to login again and rebuild an user scoped variables if a server fails, but at least the user will keep getting web pages. I have very successfully used load-balancing for several years now.   As for round robin dns, there should be no problems at all. Once a user has a server and a USR, Witango should be fine.   Robert   -----Original Message----- From: Diodeus [mailto:[EMAIL PROTECTED] Sent: Thursday, June 10, 2004 10:43 PM To: [EMAIL PROTECTED] Subject: Re: Witango-Talk: Round Robin DNS     ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf
