Cloud computing
Date：2018-12-17
Cloud computing is the addition, usage, and interaction pattern of internet-based services, typically involving the provision of dynamic, scalable, and often virtualized resources through the internet. Cloud is a metaphorical term for the internet and the internet. In the past, clouds were often used to represent telecommunications networks in graphs, but later they were also used to represent abstractions of the internet and underlying infrastructure. Therefore, cloud computing can even allow you to experience 10 trillion calculations per second, with such powerful computing power to simulate nuclear explosions, predict climate change, and market trends. Users can access the data center through computers, laptops, mobile phones, and other means to perform calculations according to their own needs.
There are multiple definitions of cloud computing. There are at least 100 explanations for what cloud computing is. [3] At present, it is widely accepted that the National Institute of Standards and Technology (NIST) in the United States defines cloud computing as a pay per use model that provides available, convenient, and on-demand network access to a configurable pool of computing resources (including networks, servers, storage, application software, services) that can be quickly provided with minimal management effort, Or engage in minimal interaction with service providers.

XenSystem, as well as Intel and IBM, which are already very mature overseas, are expanding the scope of various "cloud computing" application services and their influence is immeasurable.
Due to the continuous deepening of cloud computing applications and the expanding demand for big data processing, users have seen a significant increase in demand for powerful and highly available 4-way and 8-way servers, with a year-on-year growth rate of over 200% for this segmented product.
IBM has a considerable advantage in this field, and what is more noteworthy is that Inspur achieved a market share of over 15% in 2011 with only the Tissot TS850 product, ranking IBM by less than 1%. After HP, it became one of the top three high-end servers in China.
The 32 way high-end fault-tolerant server Tissot K1 system developed by Inspur with nearly one billion yuan in 2012 has not yet been launched, and its huge market potential needs to be explored.

Cloud computing is often confused with grid computing, utility computing, and autonomous computing.
Grid computing: a type of distributed computing, consisting of a group of loosely coupled computers, commonly used to perform large-scale tasks;
Utility computing: A packaging and billing method for IT resources, such as measuring costs separately based on computation and storage, similar to traditional public facilities such as electricity;
Autonomous computing: A computer system with self-management capabilities.
In fact, many cloud computing deployments rely on computer clusters (but differ greatly from the composition, architecture, purpose, and working mode of grids), and also absorb the characteristics of autonomous computing and utility computing.
