What is the difference between cloud platform and server virtualization? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Server virtualization is actually a part of cloud computing platform technology. The construction of resource pool is not only the basis of resource management and capability service, but also the underlying core of cloud computing. It usually includes server virtualization, storage virtualization and network virtualization.

Server virtualization

Abstract the physical resources of the server into logical resources, and turn a server into several or even hundreds of virtual servers isolated from each other. We are no longer limited to physical boundaries, but let hardware such as CPU, memory, disk, and Ithumb O become "resource pools" that can be dynamically managed, thus improving the utilization of resources, simplifying system management, realizing server integration, and making IT more adaptable to business changes.

The mechanism of server virtualization is to attach virtualization management programs to independent PC servers, and then implement multiple upper operating systems based on underlying virtualization, so as to build a similar "one virtual many" environment. Traditional virtual operating systems such as virtual hosts and virtualized servers also require independent storage and network connections, so there is the concept of storage virtualization and network virtualization.

Two other core virtual technologies in cloud platform

Storage virtualization

The most popular understanding of storage virtualization is the abstract performance of storage hardware resources. Provide useful full-featured services uniformly by integrating one (or more) goal (Target) services or functions with other additional functions. Typical virtualization includes the following situations: shielding the complexity of the system, adding or integrating new functions, simulating, integrating or decomposing existing service functions, and so on. Virtualization acts on one or more entities that are used to provide storage resources and / or services.

Network virtualization

At present, it is generally believed that network virtualization is a kind of abstraction of physical network and its components (such as switches, routers, etc.) and separation of network traffic. By using network virtualization, multiple physical networks can be abstracted into a virtual network, or a physical network can be divided into multiple logical networks. at present, common network virtualization applications include virtual local area networks, namely VLAN, virtual private network VPN, and virtual network devices.

The realization of cloud computing is inseparable from the resource pool, and the technical implementation of the resource pool is inseparable from the virtualization technology. Server virtualization, storage virtualization and network virtualization are the core, and the functions of mutual cooperation, interactive access and secure access are realized among them.
