The first companies to implement cloud computing practices within the enterprise, such as Google, Amazon, Microsoft, have invested most in cloud computing, such as HP, IBM and so on, are multinational companies headquartered in the United States, while Around these giants also appeared a lot of small and medium-sized enterprises to provide cloud computing industry in the downstream part of the product services, there are many viable cloud computing business model. Looking back on the development of cloud computing in the United States in the past 5 years, the observation and analysis of the participating parties--enterprises, government, institutions of the performance measures, the development of China's cloud computing industry will have a very positive reference significance. ...

There are two main ways to store data: Database and filesystem, and the object-oriented storage are developed behind, but the overall thing is to store both structured and unstructured data. DB is initially serviced for structured data storage and sharing. FileSystem storage and sharing is large files, unstructured data, such as pictures, documents, audio and video. With the increase in data volume, stand-alone storage can not meet the needs of structured and unstructured data, then in the era of cloud computing, there is a distributed ...

Cloud computing (Cloud Computing) is the development of distributed processing (distributed Computing), parallel processing (Parallel Computing) and Grid computing (grid Computing), 　　or the business implementation of these computer science concepts. The rationale for cloud computing is to distribute computing across a large number of distributed computers, rather than on local computers or remote servers, where enterprise data centers run more like the Internet. This allows the enterprise to switch resources to ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

Cloud computing is in full swing in the domestic rapid Mengjin, from the government to it giant enterprises, from operators to IDC service providers, as if all of a sudden have become cloud computing service providers, to provide users with a variety of cloud services.　　In this technology-driven cloud computing "expansion", users are still "foggy", for the cloud service providers, more need is innovative service model. Shortly before the six free services, China's network announced that almost all its applications are transformed into cloud services, while the six industry recognized fee business into free services, including free 5M bandwidth, 2G free space ...

Cloud？ It is a big enterprise to enjoy the strength of services, for our small and medium enterprises is still a concept. "At present, cloud computing in the world does not have a unified, unanimously recognized definition, from the major enterprises and organizations derived from the concept of cloud computing countless, but there are few practical products and services to support." This makes the cutting-edge technology not deep understanding of the small and medium-sized enterprises to cloud computing produced "there is a cloud on the horizon, like the fog like rain and wind" fuzzy understanding, most of them did not feel the cloud for the enterprise brought ...
