What kind of setup does a web site like ebay have?

Including multiple datacenters and internet connections they have a multi-tiered server setup.

Windows NT running IIS front-end webservers (so says netcraft) which connect to backend database servers. I believe they use to run Sun and Oracle but are moving/moved to HP and Oracle on the backend.

hrm if their using m$ for the webservers then i wonder how many times they have been hacked :P

Yes it's IIS with custom ISAPI executables.

And remember it was a OS upgrade from Sun that knocked eBay down a couple years ago.

It was a memory upgrade that did it. Sun had a problem with some memory configuration which caused servers to core dump IIRC.

Here is some info.....

EBay said a failure in software from Sun Microsystems caused its service to go down at 7:50 p.m. Pacific Time on Thursday.

eBay blacks out yet again
http://news.com.com/2100-1017-226987.html?legacy=cnet A corrupted database was blamed for the Friday disruption, leading the company to put on a full-court press to get the site back online. In particular, eBay pointed a finger at software from Sun Microsystems.

hrm if their using m$ for the webservers then i wonder how many times they have been hacked :PI am sure the same could be said if they ran Linux.

lolol its no telling howmany times they got hacked to tell you the truth i thought they ran freebsd like most of the major websites take care

They run a clustered service naturally.. Would be pretty hard to get behind to the webserver itself. And if you get into one webserver.. what good would that do? They just take it out of the cluster immediately and wipe the sucker, put on a clean install and put it back into the cluster.

Only a few people would see the hack. No one would really notice.

You would more likely want to do something with their cache servers (wich usually have their own special build of an operating system) or dns. So that would require alot of special knowledge if you ever could penetrate their firewalls and all the cluster hardware.

Or a dos attack would be more likely to ever hurt them.

Ebay is a company that makes business for $420 a second. I think they can afford live people monitoring their network for hack attempts 24/7. :)

lolol its no telling howmany times they got hacked to tell you the truth i thought they ran freebsd like most of the major websites They don't really get hacked.

BTW, most major sites do not run FreeBSD.

Yes and no. The beauty of Linux is that it's open source, Windows is not. Now if a security advisory was released for a Linux app... i'm sure they have some competant programmers working for them who could even write up a quick code patch.... As for Windows, well, you wait on them or shut your service down.
