People have been asking me for a little technology overview of how Engine Yard is structured. I’ll give a small run down here.

Engineyard.com new site is up.

I am really excited to announce that we just launched our new redesign at EngineYard.com. We have been working very hard to get the first cluster up and its running very very nicely. I am still hard at work on the control panel for making it very simple to deploy your apps to the cluster and hope to be done soon.
Damien Tanner from New Bamboo did the design work for us and we are very happy with it.

Apache2.2 vhost template for mongrel clusters

Posted by ezmobius Mon, 12 Jun 2006 06:45:00 GMT

Just wanted to share a template vhost for use with apache2.2/mod_proxy_balancer → mongrel_cluster. This vhost takes care of making apache serve all static and page cached requests while forwarding all dynamic requests to the mongrel_cluster.

Thanks to Bradley Taylor author of mongrel_cluster and owner of RailsMachine.com for this config.
