A proper definition of cloud computing server characteristics is: namely, high density (High-density), low energy consumption (Energy-saving), easy to manage (Reorganization ), system optimization (Optimization).

High-density (High-density): the future of the cloud computing center will be increasingly large, while the land is inch by inch, the server room space is stretched, how to accommodate more computing nodes and resources in the limited space is the key to development.

Low energy consumption (Energy-saving): the proportion of investment in power equipment and air conditioning system in the construction cost of cloud data centers reaches 65%, while 75% of the operating cost of data centers will be energy costs. It can be seen that the reduction of energy consumption for the data center is extremely important work, and cloud computing servers are the core of energy consumption.

Easy management (Reorganization): a huge number of servers is a big problem to manage, through the cloud platform management system, server management interface to achieve easy deployment and management is the development of the cloud computing center must consider factors.

Optimization: In a cloud computing center, different servers are responsible for different applications. For example, some are virtualization applications, some are big data applications, different applications have different needs. Therefore, optimization for different applications and the formation of a targeted hardware support environment will give full play to the advantages of the cloud computing center. This will put forward new requirements for the server, cloud computing will redefine the server.
