Unintentional load test

I've been a little out of touch with this blog in the last month or so. Ever since Thanksgiving things have been crazy, especially at work with the busy season.

Over the last year we have made some great efforts to dramatically increase our stability as well as availability by increasing redundancy to remove single points of failure. This was on many levels including the networking layer by introducing an HA firewall pair, and an HA load balancer pair. We also built out our server infrastructure by implementing 3 web servers for the load balancing, as well as clustering our database hardware and our application server hardware. All of this was intended to be able to easily handle the load of the retail busy season, between Thanksgiving and New Year's weekend. To be able to really know how much we could handle we wanted to load test the infrastructure top to bottom.
