Check the Livejournal presentation by Brad Fitzpatrick, the Flickr
presentation by Cal Henderson -- I found them very helpful.

Hi, I was wondering if anybody could explain to me how how delicious
is deployed (currently, but also before Yahoo acquired delicious, when
this presumably was a much smaller operation)? I just know that there
are multiple servers, but I'm not sure how the (MySQL) database and
(Perl) processing is distributed among them. I thought this would be
an interesting case study in the deployment of a highly available web
apps, since there are lots of writes, aggregates are calculated across
all users, and (it seems) all the data is in the DB, (e.g., how is the
DB synchronized among all the servers?).
I'd also be interested in hearing about what major changes occurred
over time due to such scalability issues (i.e., how things started,
and how they became the way they are today).
(I'm trying to learn how scalability is achieved in real-world web
apps in general, so any pointers to references on this matter would
also be appreciated.)
Thanks in advance.
