What are the advantages of physical servers and cloud servers respectively? In view of this problem, today the editor summarizes this article about the server, hoping to help more friends who want to solve this problem to find a more simple and easy way.

What is a server

The server is a high-performance computer in the network environment, which can listen to the service requests submitted by other computers (clients) on the network and provide the corresponding services.

Its high performance is mainly reflected in high-speed computing power, long-term reliable operation, strong external data throughput and so on.

The server is like a stepping stone, it is the necessary carrier to open the website, the website users without the server can not browse.

For example, web server is needed to build a website; game server is needed to run games; streaming media server is needed to build live broadcast platform; database server is needed to build database; ERP server is needed to build ERP system.

2. The difference between physical servers and cloud servers

The composition of the physical server is basically similar to that of the microcomputer, including processor, hard disk, memory, system bus and so on. They are specially designed for specific network applications and are independent servers.

Similar to the general computer architecture, but due to the need to provide highly reliable services, it requires high processing capacity, stability, reliability, security, scalability, manageability and so on.

Physical server

The opposite is the cloud server. CVM is a simple, efficient, secure and reliable computing service with flexible processing capacity.

Its management is simpler and more efficient than physical servers. Users can quickly create or release any number of CVMs without purchasing hardware in advance.

Advantages of CVM:

1. Technology: cloud computing technology is used in cloud computing, while cloud computing technology integrates computing, network, storage and other software and hardware technologies. Physical servers, on the other hand, are independent and do not integrate these resources.

2. Security: the CVM has natural protection against ARP attacks and MAC spoofing, snapshot backup, and data is never lost. Physical servers do not have this capability.

3. Reliability: CVM is based on server cluster, so hardware redundancy is high and failure rate is low, while physical servers have relatively less hardware redundancy and high failure rate.

4. Flexibility: users can increase their configuration online in real time, and there is more room for expansion, while physical servers have this limitation. If there is a new application, you can only buy another one.

5. Computability: the computing power of cloud servers is 4 times that of independent servers with the same configuration, which can meet the requirements of high-performance computing.

6. Stability: CVM can be automatically migrated from failure, which means that if a CVM fails, the applications above will be automatically migrated to other CVMs.

7. Security: high security is one of its major advantages. Cloud service providers support professional security technology, security team, monitoring mechanism, and have long-term experience in security protection work. If a website or application is placed on a cloud server, it is less likely to suffer from ddos attacks and data leakage. If it is a sensitive business, cloud security services such as security guards can be added to achieve more stringent security protection.

To sum up, physical servers and cloud servers have their own advantages, and you have to choose one of them according to your own situation. If you want to learn more about related articles, you are welcome to follow the industry information channel.
