The key premise behind Schooner is that there's an opportunity to do a greater degree of systems integration through open source. Busch described to me how in the past there was always great cooperation between the OS team, the compiler team, the chip team, and so on, to optimize overall system performance. But with the emergence of commodity components, CPUs, motherboards, and the like, each subsystem is locally optimized, but overall system performance is not. Busch realized there is an opportunity with open source technology to change the game by getting in and tuning the heck out of every software component to maximize throughput and efficiency. The net result is that with Schooner you can consolidate multiple servers and achieve higher performance at a lower operating cost.
No doubt there are going to be many ways to slice and dice this market. But it's great to see that open source is powering a new level of innovation in the industry.
