服务器和云服务器有什么区别(服务器 云服务器 关系)

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, the capacity 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.
