OT: Ebay servers

[Roman]

Out of curiosity, anyone knows what does Ebay run on and how many servers ?

The front-end page says "Java Technology, powered by Sun" in top-right
corner. When you click, it reads: "eBay is Java™ Powered running on
powerful Sun Fire UltraSPARC® and AMD Opteron™ servers ..."

My browser gets the following headers, they seem to have mix of
technologies:


www.ebay.com
Server: Microsoft-IIS/5.0
Server: WebSphere Application Server/4.0

include.ebaystatic.com
Server: Microsoft-IIS/5.0

pics.ebaystatic.com
??? (no server signature)

srx.main.ebayrtm.com
Server: Microsoft-IIS/5.0
Cneonction: close (hmm, interesting)
Server: Apache-Coyote/1.1

us.ebayobjects.com
Server: DCLK-AdSvr

banners.ebaystatic.com
Server: Microsoft-IIS/6.0

my.ebay.com
Server: Microsoft-IIS/5.0
Server: WebSphere Application Server/4.0

Its all run on the one server, Win NT, 486 proc, 16mb sd ram, 6.4Gb
5400rpm ide hdd, content delivered by MS personal web server.

Flamer.

Well, Java is designed to run on just about any platform, and WebSphere
Application Server [1,2] is a J2EE [3] environment owned by IBM.

[2] http://www.ibm.com/software/webservers/appserv/was/
[3] Java 2, Enterprise Editon, http://java.sun.com/javaee/

Most of them are IIS, does Microsoft server run on UltraSPARC ?

You assume too much, too. What are they running on their database
server? I don't think their web servers and databases are on the same
servers. A machine running, say, an Oracle database server (or a
different database server, for all I know) could be the one(s) using
UltraSPARC for all we know.

And somewhere on their site:

eBay has chosen Sun's Solaris Operating System, the most advanced
operating system on the planet, and its Sun Fire servers to help
power The World's Online Marketplace.

Big emphasis on _help_. It doesn't say that the entire server room runs
on Solaris. The ones running IIS on Windows might just be the front end
servers.

Don't quote me on this, but I believe most of the heavy lifting at the
site is handled by native code through ISAPI.

I was curious and asked if somebody knew. I found some information that
they are actually running Oracle, but I was wondering more about the
webservers and their number to keep up with the traffic. When one clears
the cache and loads Ebay front page, browser downloads 350k of files
from various servers.

It apears to me that dynamic content is generated using IIS and ISAPI
extension (URI is /ws/eBayISAPI.dll). Thats only my speculation as
eBayISAPI.dll can be anything and server signatures could be disguised too.

I did read some article somewhere that in 1999 Sun server failed and
Ebay was down for 22 hours and then they selected IBM as a solution
vendor after tinkering with Microsoft ASP.NET.

And somewhere on their site:

servers.

Which signature in headers would be the front-end if they have multiple
"Server: xyz" records (see my original post) ? Or the order does not
mean anything ... ?
