Agile Ops
or, what's this DevOps thing everybody is talking about Agile in software development is an attempt to be more real - rather than attempt to predict the future, the methodology is all about taking stabs and correcting with a fast feedback cycle. Start producing real value quickly, and keep chasing the value fanatically. In a recent Openstack meetup discussing Swift an attendee asked - so swift has all these parameters, do you have good guidance on how to set them ? A traditional approach would involve enormous efforts attempting to predict workloads, methodically simulating them in a lab environment, and laboriously attempting to tune parameter after parameter to find the optimum setting for those workloads. Can you predict what would happen? You will end up deploying optimized the system based on the lab results driven by the simulated workloads. By the second week in production you realize that the actual workloads are substantially different t...
