| Abstract: | This paper introduces the backgrounds, concept, basic principle and infrastructure of cloud computing firsdy.Then it surveys implementation mechanism of clouding computing based on the instances of Google.Cloud computing is the system in enterprises based on the concepts of computer science. These concepts include parallel computing, distributed computing and grid computing. Google has his own platform of cloud computing. It provides implementation mechanism and infrastructure of cloud computing. This paper surveys the platform of cloud compudng：Google File System, Distributed database-BigTable and Map/Reduce. Finally the paper analyse the challenge of cloud computing. |
