虚拟主机和云服务器哪个好(云服务器和云虚拟主机有什么区别)

The two are completely different concepts. A virtual host is what everyone usually calls space. It is a part of the virtual capacity divided on the server hard disk using software. What is shared is the server IP, bandwidth and other resources. The programs it supports are also configured on the server by default. The functions are limited. It is generally used for small websites. The cloud host is also a cloud server. In fact, the current domestic cloud technology is still relatively weak. The so-called cloud service means that everyone shares all resources. The space is unlimited and the bandwidth is unlimited. Large. It is much faster than traditional servers in terms of processing power and running speed. At present, there are very few IDC companies in China that truly master cloud technology. At the same time, the price is relatively high. Compared with virtual hosts, it has an independent IP .Bandwidth resources. Various operating systems and application software can be installed as needed. It is much more powerful than virtual hosts in terms of functionality and security.

Cloud virtual host is also a kind of virtual host product. Compared with traditional virtual host, it is stable in performance and The price is better, and it also has many advantages such as high online rate, no need for filing, and intelligent fault tolerance. Cloud virtual hosting also has a highly available cloud architecture, which stores site data in cloud storage. It allows a unified service platform to aggregate many resources together, giving users a variety of choices. It also supports additions at any time, maximizing the website's energy consumption efficiency and minimizing operating costs. The resources of cloud virtual host will not be limited by a single product and service, and can meet a variety of services and needs.

Cloud server is also usually called cloud host or cloud computing server. It is one of the host products in the cloud computing server system. The technology used by the cloud server is similar to the virtualization technology of the VPS server. It is also understood as an upgraded version of the VPS. The difference is that the cloud server is divided into multiple servers similar to the server through a group of clustered servers. space.

The difference between cloud virtual hosts and cloud servers:

Cloud virtual hosts are further divided from cloud servers. Virtual host management software is used to divide the cloud servers into multiple Small spaces with different models. Although cloud servers and cloud virtual hosts integrate high-performance servers and high-quality network bandwidth through cloud computing technology, the price will be cheaper than traditional ones. The difference is that the cloud virtual host runs on each server node in the cluster server at the same time. That is to say, an identical site can be found in each node server in the cluster. At the same time, the configuration used by the site in each node server and data are the same.

A physical server is a high-performance computer that provides services to clients. It is the core infrastructure equipment for building cloud computing and data centers. Cloud servers and virtual hosts are both based on cloud computing technology. conducted research and development. The differences between servers, cloud servers and virtual hosts are mainly reflected in the following aspects:

1. Performance: The performance of the server affects the use of subsequent development, so the server must be responsible for services, The ability to guarantee services. The high performance of physical servers is mainly reflected in high-speed computing capabilities, long-term reliable operation, and powerful external data throughput capabilities. It is the best in terms of performance. Since the cloud server is public in nature, its performance bottleneck is restricted by the hardware of the underlying server. Once the data access volume of the virtual host is too large during use, it will become slow, and upgrading the virtual host is also troublesome.

2. Security: Traditional physical servers are independent servers with only one operating system installed directly on the server and dedicated to a single tenant. Tenants are based on physical isolation and have the highest security. The cloud server is based on the cloud computing architecture and can autonomously switch failed nodes to normal hosts. It has strong stability, provides a variety of data recovery measures, and is safe. Since the bandwidth of the virtual host is shared, if the virtual host uses a shared IP, the security will be reduced.

3. Affordability: With the promotion of cloud platform products gradually gaining public recognition, the development prospects of the cloud are getting better and better, and the price of cloud servers has also been reduced. In this way, users can not only save their own costs, but also obtain high-performance, flexibly expandable computer resources. Cloud servers are more cost-effective than traditional physical servers. Compared with cloud servers with the same configuration, virtual hosts are cheaper.

4. Flexible scalability: Cloud servers can support elastic expansion, and you can choose a cloud server and pay according to your needs. When the server performance cannot meet the business development needs of the enterprise or users, it can be expanded at any time, and the cloud server's host CPU, memory, hard disk, bandwidth and other system configurations can be upgraded flexibly. Upgrading or expanding the virtual host is relatively troublesome, and requires re-renting new virtual host space.

5. Skill threshold: Cloud servers usually provide advanced management functions in the console, making the management of cloud servers easier. Virtual hosts are also relatively simple to manage and more efficient to use. Physical servers require server configuration knowledge, detailed planning and management, and understanding of related required resources, which requires a relatively complete knowledge reserve.

Generally speaking, the comprehensive capabilities of cloud servers are the most average. With the continuous development of cloud computing technology, moving to the cloud is the general trend in the information construction model. The UMC cloud management platform independently developed by Datacom is a unified management center for cloud platform development, deployment, management, and operation and maintenance. It provides unified management of K8S cluster configuration, operating status, etc., and meets the four basic elements of cloud native: containerization, Microservices, DevOPS continuous delivery, multi-tenant management. The AEAIiPaaS platform is formed by the combination of UMC, containerized AEAI suite and CI/CD management mechanism. Mainly through connection and collaboration, business integration is achieved to support the business middle platform, and data integration is achieved through connection and sharing to achieve data middle platform.
