Isn't this the type of thing Akami does?? Hope I got the name right. If I'm remebering right, they mirror a website to multiple geographic locations, and requests for the site are served by the location closest to them (thus improving speed).

I forgot expensive as well... client should be deep pocketed.. whether you do it yourself or opt for proven products... it take enough work to call it a skill.. hopefully others will chime in on this topic..... First, outsource your DNS... someplace you have the ability to dynamically update your IP info via the web when you need to live time... See Enom.com service... plug in your multiple locations separate Nameservers.. be sure to register those initially as nameservers with INternic... >From the switching layer, companies like F5 and Coyote Point has DNS loaded switches/load balancers that have geographic distribution... you of course need multiple units on each end for redundancy.. it gets expensive... but they are cheap on Ebay... >From the disk end... I believe you can easily map a remote drive via Windows.. based on IP with proper permissions.. once you do that, you can run one of the may mirror packages to push the flat files into synchronization.. ideally, one is the master and one is the servant... Folks like EMC offer addon software (20-40k) for their Symmetrix system that allows such... but mapping and lowly software likely will cut it for you.. or an FTP client with duplication feature set... >From the database side... SQL Server 7 + has some transaction stuff... I don't use such.. but mature databases will have distribution facilities... Oracle and MySQl also have a good set of tools to accommodate...be sure to buy some aspirin before you start...getting it to work and synching seamlessly is another feat... Those are the pieces... With the multiples and DNS stuff, you also can get full usage of all gear versus having unused gear that isn't regularly tested and operational online... highly recommend doing it that way.. otherwise when something happens you might be embarrassed. -paris -----Original Message----- From: Michael Ross [mailto:[EMAIL PROTECTED]] Sent: Friday, January 25, 2002 17:50 To: CF-Talk Subject: Re: Geographical dispersion See if you can find a hosting company that does load balancing......M aybe try co-locating 2 servers in different places with Windows 2000 server to load balance......or find someone that has a hardware load balancer.....without the client actually having their own physical lo cation/network available it may be difficult.... >>> [EMAIL PROTECTED] 01/24/02 09:10PM >>> Hi! We have a client who needs their ColdFusion site mirrored geograph ically. They need it so that if Seattle gets hit with an earthquake (since we are out of the Seattle area), the mirrored site in Chicago (for example) will automatically pick up without any site outage. I am not familiar wit h all the details of how mirroring works, but the hosting companies I have talked to so far cannot offer this service... they say that mirroring it in the same rack is not a problem, but mirroring across the country poses so me kind of problem. Is there a hosting company that anyone knows of that can take care of this situation? We actually have two applications for a solu tion to this problem. We have this new site that needs to be hosted and mirr ored, but we also have a Linux server in a data center here that needs to b e mirrored somewhere else in the country also (with auto switch over). I thought Akamai would be a solution, but the rep from there said that they do only hit dispersion, but not actual content and site mirroring. Any ideas? Sorry if some of the terminology is off...kind of over my head here.. :) Thanks, Christine [EMAIL PROTECTED] _____________________________________________________________________ _ Get Your Own Dedicated Windows 2000 Server PIII 800 / 256 MB RAM / 40 GB HD / 20 GB MO/XFER Instant Activation � $99/Month � Free Setup http://www.pennyhost.com/redirect.cfm?adcode=coldfusionb FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/[email protected]/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists ______________________________________________________________________ Dedicated Windows 2000 Server PIII 800 / 256 MB RAM / 40 GB HD / 20 GB MO/XFER Instant Activation � $99/Month � Free Setup http://www.pennyhost.com/redirect.cfm?adcode=coldfusiona FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Archives: http://www.mail-archive.com/[email protected]/ Unsubscribe: http://www.houseoffusion.com/index.cfm?sidebar=lists
