DISTRIBUTED COMPUTING APPROACHES FOR SCALABILITY AND HIGH PERFORMANCE

摘要

Distributed computing is a science which solves a large problem by giving small parts of the problem to many computers to solve and then combining the solutions for the parts into a solution for the problem. This distributed computing framework suits to projects, which have an insatiable appetite for computing power. Two such popular projects are SETI@Home and Folding@Home. Different architectures and approaches for distributed computing are being proposed as part of the works progressing around the world. One way of distributing both data and computing power, known as grid computing, taps the Internet to put petabyte processing on every researcher's desktop. Grid technology is finding its way out of the academic incubator and entering into commercial environments. Cloud computing, which is a variant to grid computing, has emerged as a potentially competing approach for architecting large distributed systems. Clouds can be viewed as a logical and next higher-level abstraction from Grids.
