What this article shares with you is about how the cloud server works. The editor thinks it is very practical, so I share it with you to learn. I hope you can learn something after reading this article. Let's take a look at it with the editor.

Virtualization technology

1. Using server virtualization, the CPU, memory, disk and other hardware of the server are managed centrally, and the resource utilization efficiency is improved through centralized dynamic allocation on demand.

two。 Storage virtualization separates the logical view of storage resources from physical storage to provide seamless resource management for the system. However, the degree of storage standardization is low, and the technologies of different manufacturers should consider compatibility.

3. Memory virtualization is the management of memory by computer memory system, which makes the upper application have continuously available memory and splits multiple fragments on the physical layer to meet the allocation of memory and necessary data exchange.

4. Network virtualization uses software to separate network power from physical network elements and has something in common with other forms of virtualization.

Resource scheduling

Virtual machines can break through the limitations of a single physical machine, dynamic resource adjustment and allocation to eliminate a single point of failure of servers and storage devices, and achieve high availability. When the host of a computing node needs to be maintained, the virtual machine running on it can be migrated to other idle nodes without downtime through hot migration technology. When the computing node is physically damaged, it can also migrate its business to other nodes to run in about 3 minutes, which has a very high reliability.

About distributed Stora

Distributed storage is used to integrate a large number of servers into a supercomputer, providing a large number of data storage and processing services. Distributed file system and distributed database allow access to common storage resources to realize IO sharing of application data files.

The above is how the cloud server works. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
