Lessons Learned from Amazon EC2 outage

OK I’m back from the holidays and just recently presented a webinar on how to protect entire virtual infrastructure in the cloud and the risks of having your entire datacenter residing on a few virtual servers. Unlike the old days if a server went down the only impact was what ever the application that was running on that server. Now with consolidated virtualized infrastructure if a physical server goes down there could be a dozen virtual machines go offline simultaneously. I believe Amazon still met the SLA but this article should serve as good information for anyone looking to implement a 100% virtualized environement without some sort of loal failover capabilities.

Without warning on January 2, all of the specialized, high-capacity Amazon EC2 instances that run its popular application and development service disappeared in the blink of an eye. Twenty-two virtual machines, approximately $20,000 per month in hosting fees for high-memory m2.2xlarge instances, suddenly vanished, leaving Heroku’s estimated 44,000 running applications in the lurch.
Amazon blamed a routing device in its Virginia data center, and the service was back up in an hour. But Oren Teich, Heroku’s product developer, said this is one of the many important lessons new ventures and businesses need to learn before they decide to work entirely in the cloud. Traditional contingency planning doesn’t go far enough, he said: expect the unexpected.
