Ok, so I'm on the verge of making a huge website, that's the plan anyways, and I need it to be run off of a HUGE database. What would you guys suggest, mssql, mysql? for running the website apache, IIS, Windows SQL Server? I've pretty much made up my mind about PHP, so I guess the initial aim would be Apache and MySQL, but I'm open for suggestions..

I've made several websites with php, apache and mysql, and it worked fine. I'm just worried about websites with a lot of traffic and a lot of search functions, if that will overload Apache and MySQL.

I'm kind of curious as to what the big websites out there are using? eBay? Amazon? Nba.com? Cnn.com? Or sitepoint for that matter, what database do you guys use? And what kind of server? What do you guys think?

If any of you have experience with huge websites please share you experience I want to make sure to get it right from the getgo..

thanks in advance..
