Why Drupal?

• Original site was built on custom PHP code• Custom PHP code was not reliable or scalable• Make the site more interactive: comments, voting, ratings• Drupal has a highly flexible architecture• Many developers working on similar issues accelerated troubleshooting as opposed to relying on proprietary experts

Early development

Development and staging

environments

• Development moved out of house to give you

flexilibity

• Switched to using Jmeter across 3-4

development servers to simulate staging

• Full log ins, ratings, and all the interactive stuff

he needed to do

Early architecture

• Promotional sub-sites drive specific traffic• Sporadic volume spikes• Separating anonymous and named user traffic • Traffic increases require ongoing database query tuning

• Tied to programming – difficult to anticipate

Acquiring ParentsClick

• Strong technical team

• Expertise in Drupal 6

Current architecture

Akamai Content Delivery Network

• Points of presence, International

• Media Extender for anonymous pages

• CDN for Images, Javascript, CSS

• Custom CDN module

• Authcache module distinguishes Akamai traffic

Project runway, and Amish Grace

Web servers

• Apache Webserver and Lighttpd as the origin for

Akamai

• Apache, APC

• Separate Memcache server now, isolate and

improve performance. Stabilized. No net new

servers.

• During Project runway and Amazing Grace

• 15 apache- 5 memcache

• 10 apache – 5 memcache

• Get extra web servers monthly

Memcache

• Started doing page caching from memcache,

bread and butter, comments

Database servers

• 2 Masters for different sections of the site

– Multi-site and apache and different instances

– One of the sites is single sign on custom

• 3rd master is a hot backup of the 2 masters

• Each main master has 2 slaves

• Mostly slave scaling, 8 core and 16 GB servers,

plenty of capacity

• Have slow query and no-index

– Monthly review by DBA

Search

• Lighttpd servers act as Solr servers

• Linux and Java stack

• Solr configuration for HA

• Query and Index server off of both servers

Video

• Monetization of ads

• Akamai delivers videos

• Some video on Hulu

• Fast follow – all shows within 48 hours for full

• 5,000 videos online 2009

• Army wives was first time using fast follow

• Project runway cascading effect, they will go

there when they want to see a show

Network

• 3Par Fiber backbone for failover between DBs

• Isolan Network File System the vendor for the

NAS appliance between web servers

Future of Drupal scalability

• Drupal 7 database layer: Oracle support

– http://drupal.org/project/oracle

• Edge Side Includes

– http://drupal.org/node/651902

• Multi-tier caching

– http://drupal.org/node/621748

• Pluggable menu systems

– http://drupal.org/node/669608

Future of Drupal scalability

• Sequences API, savepoints for nested

transactions

– http://drupal.org/node/669794

• External Cache for reverse proxy caching

– Swap the page_cache implementation in D7 for a fake

cache

• Cloud computing scale on demand
