We should start a site named www.myspaceII.com and have it running RPG CGI
on an i5 :-) We would build a better interface (which wouldn't take much).
Then once it starts to catch on we would ask IBM to give us a big ol' 595
and open it wide open to see how well it could handle the workload of
260,000 new users a day. Man that would be a fun project to work on!
Elaine Lennox would be the person to talk to as it sounds like she isn't
opposed to alternative ways to market (i.e. most recent i5 youtube.com
videos).
The biggest constraint now appears to be the time it takes to maintain
applications across thousands of servers.
I have used MySpace.com on a very limited basis, but I just don't see how
the core software could be more than a couple 100k lines of code. Not like
it has thousands of pages with thousands of unique fields (say data) to
maintain. I know I must be over simplifying it, but it just doesn't feel
that complicated on the web frontend programming.

They said they were running about 3,000 servers. At first they tried
scaling vertically, using 16-way servers, but when that didn't work, they
went with horizontal scaling. The database server was a constraint, so they
partitioned the database across 60 DB servers.

What I more want to know, and am guessing nobody here can really
answer, is how much work (hardware, software, etc) is required to do >this
with M$ vs. IBM?
Good question. The i5 would scale better vertically, up to 64-way servers,
but at some point you'd need an architecture that scaled horizontally.
Interesting the MySpace.com guy said that he can't imagine doing this
on any other platform than Microsoft ...
He also said they pulled their hair out every night.
