Cloud Computing infrastructure for latency sensitive applications

The emerging Cloud Computing shows an attractive vision. Cheap hardware takes over workload from expensive dedicated hardware. Easy to develop, deploy and pay as you use model accelerates application release cycle and saves overall cost. The march to All-IP network continues and more latency sensitive mission-critical operations migrate to the Cloud. But the current geographical distributed Cloud introduces unpredictable latencies caused by dispatching, network transmission and computation comparing with traditional computing model. It challenges Cloud Computing and hinders the effort to migrate applications to the Cloud. This paper analyzed the latency in current Cloud and presented an empirical taxonomy of latency with four classes, gave a Cloud Computing infrastructure for different classes of latency sensitive applications with high efficiency and a proof of concept prototype.
