What are the differences between servers and cloud hosts?

Differences: 1. Different flexibility. The cloud host has good flexibility and strong scalability, and the computing power of the server will be redundant. 2. The storage mode is different. The cloud host uses network distributed storage, which can be retained in real time. For multiple copies of data, the server can only store one copy of the data in the hard disk of the local physical server; 3. Different security, the cloud host can respond to emergencies better than the server; 4. Different reliability, the cloud host can handle hotspot migration and failure The node automatically switches, but the server cannot.

The difference between server and cloud host

1. In terms of flexibility

The advantage of cloud server is to implement host facilities Exclusive and scalable. The biggest difference between cloud hosts and traditional servers is that they are more flexible, have strong scalability, and have relative advantages in terms of cost investment.

After all, for enterprises, the stored data cannot completely match the purchase or server rental. The computing power of the server will always be redundant. Even if it is just enough, in order to deal with emergencies, it is necessary to Redundancy must be achieved on the server. Cloud computing services can increase or decrease server resources at any time, allowing enterprises to enjoy Internet servers more economically.

2. Different storage modes

Cloud servers are divided by cluster servers and use network distributed storage. Data can be retained in multiple copies in real time. Even if the data is damaged, it will not affect the server's performance. normal operation. A stand-alone server only stores one copy of the data on the hard drive of the local physical server. If it is damaged, it will not be able to operate normally.

3. Security

Regular cloud service providers have made great efforts in security investment and team building to ensure the reliability of the cloud platform, so they have reliable security guarantees. The system can even proactively detect vulnerabilities in server programs and promptly notify you to check for fixes.

In addition, cloud hosts can also be more flexible and faster when dealing with emergencies. Traditional servers, as hardware, can only be upgraded at the hardware level, while cloud servers, relying on flexible scalability, can quickly increase service area resources and avoid resource shortages. Regarding the brand selection of cloud hosts, you can check which cloud server is better

4. Reliability difference

Cloud servers are supported by multiple servers, which can achieve hotspot migration and automatic switching of failed nodes, clustering There is a mirror of the cloud server on each server. When a hardware failure occurs on one of the machines, the system will automatically access the mirror backup on other machines.

Unless all servers in the cluster have problems, the cloud server will be inaccessible, which improves the stability and security of host rental. When the server needs to be upgraded or restarted, the normal operation of the website can be guaranteed.
