Brief Introduction
Apache Hadoop is a framework for running applications on large cluster built of commodity hardware. The Hadoop framework transparently provides applications both reliability and data motion. Hadoop implements a computational paradigm named Map/Reduce, where the application is divided into many small fragments of work, each of which may be executed or re-executed on any node in the cluster. In addition, it provides a distributed file system (HDFS) that stores data on the compute nodes, providing very high aggregate bandwidth across the cluster. Both MapReduce and the Hadoop Distributed File System are designed so that node failures are automatically handled by the framework.
In 2006,Google engineer Christophe suggest Google CEO Eric Schmidt the idea of "cloud computing“ at the first time, under the support of Schmidt, Google rollout "Google 101 plan "and formally proposed the concept of “cloud ".

Cloud Computing Summary
Cloud computing is a kind of network service and is a trend for future computing
Scalability matters in cloud computing technology
Users focus on application development Services are not known geographically
The specific characteristics
Data in the cloud: not afraid to lose, do not have to back
Google's concept of “cloud computing” is a picturesque phrase, to describe Google's business model and computing technology architecture in a romantic way.therefore, cloud computing consists two levels of meaning, in commercial level, just the "cloud“; in the technical level is "computing",combined the cloud and computing to illustrate that Google is different with traditional software and hardware companies in business models and computing architecture. This is just a very beautiful and very romantic metaphor.
