Book Description
My career in performance began, as you might guess, with a catastrophe. I was working as an architect at a marketing company that runs surveys, and one of our promotions took off. It was featured on the AOL homepage, and thousands of people began visiting our website. What started as a great success quickly turned into a crisis as our application servers began to fall over under the unprecedented load.
Our application environment was actually pretty heavy-duty for the time. We had a Cisco load balancer in front of four WebLogic instances running on Solaris with an Oracle cluster behind them. We were grossly underprepared, however, for the load we were about to receive. As soon as the promotion appeared on the AOL homepage I watched our session counts start climbing from 10 to 50, 500, and 5,000, at which point things started heading downhill quickly. I was restarting the WebLogic instances as fast as I could, like a terrible game of Whack-a-Mole. Eventually, however, it got out of our hands – we had to ask AOL to remove our survey from their homepage, because we simply couldn’t handle the traffic.
