What does cloud computing mean?

Cloud computing (cloud computing) is based on the increase, use and interaction model of Internet-related services, which usually involves providing dynamic, easily scalable and often virtualized resources through the Internet.

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.

The National Institute of Standards and Technology (NIST) defines cloud computing as a pay-per-use model. The mode provides available, convenient, on-demand network access into a configurable shared computing resource pool (resources include networks, servers, storage, application software, and services). These resources can be quickly provided with only a small investment. Administrative work, or minimal interaction with service providers. XenSystem, as well as Intel and IBM, which are already very mature abroad, the scope of various "cloud computing" application services is expanding day by day, and their influence is immeasurable.

Due to the continuous deepening of cloud computing applications and the expanding demand for big data processing, users' demand for 4-way and 8-way servers with powerful performance and high availability has accelerated significantly. This segment of products has increased year-on-year. The speed exceeds 200%.

IBM has considerable advantages in this field. What is more noteworthy is that Inspur achieved more than 15% market share in 2011 with only one product, Tissot TS850, ranking with a gap of less than 1%. After IBM and HP, they have become the top three high-end servers in China.

The Tissot K1 system, a 32-channel high-end fault-tolerant server developed by Inspur in 2012 at a cost of nearly one billion yuan, has not yet been released, and its huge market potential remains to be tapped.

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Cloud computing is often confused with grid computing, utility computing, and autonomous computing.

Grid computing: a type of distributed computing, a super virtual computer composed of a group of loosely coupled computers, often used to perform some large tasks;

Utility computing: a collection of IT resources A packaging and billing method, such as measuring costs separately according to calculation and storage, like traditional public facilities such as electricity;

Autonomous computing: a computer system with self-management functions.

In fact, many cloud computing deployments rely on computer clusters (but are quite different from the composition, architecture, purpose, and working methods of grids), and also absorb the characteristics of autonomous computing and utility computing.
