What is the difference between cloud computing operating system and common stand-alone operating system?

Cloud computing operating system, also known as cloud computing center operating system, refers to a cloud platform integrated management system based on basic hardware resources such as servers, storage, networks and massive basic software and hardware resources managed by stand-alone operating systems, middleware and databases. It has the following functions: first, it can manage and drive massive basic hardware such as servers and storage, and logically integrate the hardware resources of a data center into a server; The second is to provide a unified standard interface for cloud application software; The third is to manage massive computing tasks and resource allocation;

A stand-alone operating system, a version is generally used by ten thousand people. The technical focus is to solve the software and hardware compatibility problems of various categories and manufacturers and improve the usability. For example, Microsoft's windows operating system is a model. However, the cloud computing center has fewer operating system users and lower requirements for product availability. However, due to the huge scale of software and hardware resources managed, the technical focus is on solving usability, performance and various value-added management characteristics.

The most intuitive difference between cloud computing operating system and common stand-alone operating system is that cloud computing operating system can manage a large number of hardware devices. Take the operating system of Inspur Haiyunyun Computing Center as an example, the maximum number of devices that can be managed is more than 5000. Independent operating systems are only responsible for managing local resources.

The number of processes managed by the system varies greatly. Generally, the number of processes managed by a single operating system is usually in the order of 100, while the number of processes managed by the operating system of a cloud computing center can reach millions.

Energy management, ordinary operating system will also support energy management, but generally speaking, for simple energy control, such as hibernation, only single machine can be supported; The operating system of cloud computing center manages tens of thousands of devices, which can control energy consumption strategically, such as making sleep strategy of disk array, changing power supply and business pressure as needed. Energy-saving control is more complex and effective.
