CDNs, caching (such as with memcached or redis), and read-only MySQL slave servers can scale Drupal for anonymous, read-only traffic. However, these approaches do not help scale Drupal to handle increased dynamic page generation (such as for logged-in users) or heavy loads (such as high comment volume). Also, Drupal 7's support for read-only slave servers is incomplete, with many contrib modules not supporting it at all.

This discussion will describe a solution for horizontally scaling MySQL in a way that allows elastically-scalable read and write capacity while maintaining 100% compatibility with existing Drupal core and contrib modules.

In this webinar you will learn how to:

• Improve your Drupal site's response time under heavy load.
• Handle increased data volume as your site gains popularity.
• Dramatically reduce the cost of operating the database servers that power your site.
