Availability and Maintainability >> Performance: New Focus for a New Century

In computers, the cost of ownership runs five times the cost of the hardware. After 15 years of successfully
improving performance, it's time for a change of emphasis. We present studies of why things fail and why
they cost so much to maintain. Looking to civil engineers and diplomats for inspiration, we sketch a
research agenda and principles for "Recovery-Oriented Computing" and demonstrate how to benchmark availability.
