The server is an important carrier for storing websites. There are two types of servers: physical server and cloud server. The physical server is expensive and needs to be stored in a secure physical environment. So now, both enterprises and individuals will choose cloud servers when building websites, that is, we often hear "enterprises on the cloud".
Servers on the cloud can be divided into two forms, virtual machine and virtual machine, both of which can be used to build websites. However, there will be some differences in essence, such as price, security, availability, etc. next, I will tell you from several aspects:
The virtual machine is separated from a super large cluster server. The computing power of the virtual machine is the computing power of the whole cluster computer, and it can restart, reinstall the system, adjust the bandwidth, etc. freely. The virtual host divides a server into several small spaces, all addresses share an IP, memory, CPU and computing power, and multiple users share the resources of a server.
Servers on the cloud can be divided into two forms, virtual machine and virtual machine, both of which can be used to build websites. However, there will be some differences in essence, such as price, security, availability, etc. next, I will tell you from several aspects:

1. Resource allocation
The resources on the virtual host are shared by many people. They all share the resources of one server; The resources of the virtual machine are exclusive and are all used by one virtual machine.
2. Extensibility
Virtual hosts cannot be expanded. They can only purchase fixed models. Generally, manufacturers will set packages of different specifications. Users can purchase them on demand. If resources are insufficient, they can only choose again. The virtual machine can increase resources and expand capacity according to actual needs.
3. Environment construction
Virtual host does not need users to build their own environment, such as operating system, database, etc. The virtual machine needs to manually configure the system, database and other information.
4. Price variance
This is a very obvious difference. The virtual machine is generally one or two hundred yuan, the most expensive is only about a thousand yuan, while the virtual machine is at least a thousand yuan. The prices of the two are much different.
5. Operability
The virtual machine is easy to operate. The configuration can be realized through the relevant functions of the control panel. However, the virtual machine needs to build a server and configure the environment, which is difficult to operate.
If it is a personal website or a small enterprise website, virtual hosts can be used. If it is a large website or requires high resources, virtual hosts should be used.
