Why is cloud computing successful?
The success of cloud computing can be said to be "weather, geography, people and" the result of the comprehensive effect. "Timing" here refers to the timing of the introduction of concepts, "geographical location" refers to the concept of the technical basis, and "people and" is a lot of concepts advocates and huge market demand.

Only the fundamentals of technology and markets sometimes fail to succeed, and the right timing needs to emerge. The financial crisis that swept the world in 2008 gave the cloud a chance. Affected by the financial crisis, a large number of companies to cut it costs, the original large number of procurement has been unable to maintain. Many companies want to be able to transform it capex into opex to improve financial reporting to gain capital market support. Some small companies or individual developers in the early stages of entrepreneurship are less able to invest a lot of money in building their own IT systems or system platforms. The "consequences" of these financial crises provide a good opportunity for the booming cloud computing business.
In the past two years, green environmental protection, energy conservation and emission reduction has become a unanimous demand of the global public, but also become a "political task" in front of governments. Centralization of resources and maximization of utilization are the basic concepts of cloud computing. Cloud computing capacity as a commercial resource, hoping to provide more services with less energy consumption, such as virtualization technology, Amazon Server average CPU utilization can reach about 40%, while the average server CPU utilization can only achieve 5%~10%; through advanced energy-saving technology , Google data Center Pue (energy efficiency) value can reach 1.1~1.2, while the average data center Pue value of more than 2, that is, on the same server scale, Google's data center than the average data center can save half energy consumption. These characteristics of cloud computing are in line with the trend of green environmental protection, which makes governments start to pay attention to the role of cloud computing in energy conservation and emission reduction.

Cloud computing is not a unified concept, for Google, it is a search-oriented distributed computing; For Amazon, it is a virtualization and management technology on the server; For Salesforce, it is a software system that is provided via the Internet. But all this was technically ready by 2006--Google published four papers on GFs, MapReduce, bigtable and Chubby from 2003 to 2006, explaining the core technology of distributed computing for its search engine Virtualization technology dates back to the 1960s, IBM pioneered mainframe virtualization, and in the 1990s, VMware introduced virtualization technology to the x86 platform and was quickly accepted by the industry, which now forms ESX, Citrixxen, Microsoft Hyper-V and KVM four major virtualization platforms, which constitute the core of IaaS business, the emergence and maturity of new software architectures, such as SOA, make network software possible.
Another important foundation of cloud computing is the Internet. In recent years, the number of Internet users in the world has maintained a two-digit growth rate, the current number of netizens has exceeded 1.8 billion, the global population internet penetration rate reached 26.6%. Internet access rate has been greatly improved, the Internet has entered the "broadband" era. The average access bandwidth of the OECD's 30 member countries has reached 9Mbps, and Japan and South Korea have even surpassed 50Mbps levels. People to complete through the Internet, including information retrieval, online shopping, E-commerce and other applications to the extent of acceptance has been greatly improved, the Internet has been to some extent, the world's "trust." The basic idea of cloud computing is to provide IT services to users through the network, the development of the Internet makes this vision become a reality.
