<br>
<a href="http://www.tag1consulting.com/" target="_blank">http://www.tag1consulting.com/</a> - "LAMP Performance and Scalability<br>
Experts" tap into experience running <a href="http://drupal.org" target="_blank">drupal.org</a> and several other<br>
large scale sites to help their customers. Also have some good<br>
resources (patches, articles) on their site.<br>
<br>
<a href="http://fourkitchens.com/" target="_blank">http://fourkitchens.com/</a> - Pressflow is their distribution of Drupal<br>
which has extra patches to make it perform/scale better in a MySQL<br>
only environment. They also provide advice on hardware/software for<br>
scalability.<br>
<br>
<a href="http://www.workhabit.com/products/elastic2" target="_blank">http://www.workhabit.com/products/elastic2</a> - Provide services around<br>
scalable Drupal in Amazon's cloud, and historically have offered<br>
consulting on making Drupal scalable elsewhere as well.<br>
<br>
Acquia - nothing generally available yet, but Dries mentioned in the<br>
2009 roadmap that they will offer a product code-named "Fields" to<br>
help people scale Drupal on Amazon's web service infrastructure -<br>
<a href="http://buytaert.net/acquia-2009-roadmap" target="_blank">http://buytaert.net/acquia-2009-roadmap</a> They are probably offering a<br>
closed beta of this now - contact a sales rep if interested in trying<br>
it out.<br>
