Hmmm, interesting, a lot of the articles I remember reading don't seem to be available anymore. Too bad, there were some good war stories. They've probably all been pulled and reworked into Learning Tree "Building Scalable Web Architectures" courses. Most of what I could find about new "Web 2.0" sites seems to be all touchy-feely "user experience"-oriented stuff, no tech details on what it actually takes to generate a tag cloud or keep response time beneath the magic 3-second threshold. Here's some stuff I did manage to come up with:
A description of Slashdot's current setup (actually a few years old): http://slashdot.org/faq/tech.shtml#te050 Here's a story on Slashdot asking basically the same question the original poster did: http://ask.slashdot.org/article.pl?sid=05/05/26/1433202 A description of the growing pains of Anandtech (another geek site): http://www.anandtech.com/printarticle.aspx?i=2136 A PDF showing the infrastructure of Flickr: http://www.niallkennedy.com/blog/uploads/flickr_php.pdf Probably the most relevant -- a post describing how one site survived a Slashdotting (with a 466MHz Celeron on a DSL line): http://devnulled.com/content/2005/07/surviving-a-slashdotting-with-a-celeron -466-my-slashdot-experience/ | -----Original Message----- | From: Ross, Scott [mailto:[EMAIL PROTECTED] | Sent: Monday, 08 January, 2007 10:24 | To: Tomcat Users List | Subject: RE: web application - student need help | | Tracy Nelson. | Out of curiosity, can you point to some articles relating to the growing | pains you mentioned regarding Slashdot, Granddaddy and MySpace? | | Thanks | Scott Ross | | -----Original Message----- | From: Nelson, Tracy M.

Your | network bandwidth will give our before your connection limit. | | | i remember when websites like friendster.com came out, it was really | slow. | | now it is much faster, do you guys know where does a student learn | | about how to handle high traffic web applications? is there any | | classes? | | Your best bet is to read up on other site that had growing pains | (MySpace, Flickr or the granddaddy, Slashdot) and find out what they | did. For the most part, you'll have to find a service provider that has | the pipes you need for a price you can afford. Then worry about | partitioning your set-up: | break it up into web servers, app servers (Tomcat), and database | servers. | Try to split your app into static and dynamic pieces, that'll | (theoretically) let you cache static content (icons, logos, boilerplate | text) on the web server, which will help your response time. If your | database needs are simple (90% reads, most reads from a single table) | consider going with MySQL. It's proven itself many times over in | high-traffic sites. If you have any kind of "real" database needs, | though (transactions, complex joins, multiple concurrent updates) you'd | be better off sticking with SQL Server (or Postgres if you need multiple | servers and licensing costs become a factor). Other than that, just | learn how to instrument your system so you can analyze it to find out | where the bottlenecks are. | | Note that I've never actually done any of this, it's just what I've | gleaned from some articles on the net.
