Abstract: We argue that existing OS designs are ill-suited for the needs of Internet service applications. These applications demand massive concurrency (supporting a large number of requests per second) and must be well-conditioned to load (avoiding degradation of performance and predictability when demand exceeds capacity). The transparency and virtualization provided by existing operating systems leads to limited concurrency and lack of control over resource usage. We claim that Internet services... (Update)
