Is there any difference between physical servers and cloud services? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

For enterprises, the application of cloud hosts is very common. Then compared with physical servers, there are many differences and differences between CVM and physical server.

1. The cloud host adopts virtualization technology. Based on the huge server cluster, the efficiency of resource optimization is obvious. Source hosts in the resource pool can also be assigned to users through lease. For traditional physical servers, it usually only achieves 20% utilization. Even at peak times, it can only reach 60% to 80% and waste resources.

2. In terms of cost, the initial investment of CVM is very low. Compared with physical server lease, it is about one to ten. The CVM can be used on demand, and the service can be stopped at any time. Traditional physical servers, which can only be used after purchase, will impose a burden on enterprise assets.

3. The cloud host is easy to expand. Due to the size of the CVM cluster, the CVM can achieve flexible scalability of service functions during peak service periods. In contrast, traditional physical servers are difficult to expand due to many reasons, such as the complexity of the procurement process.

4. The host has high availability. A CVM can achieve system-level volume by setting an image method. A CVM is a cluster composed of multiple physical servers. Unless all physical servers fail, the operation of the CVM will be affected.
