VPS server: VPS is a physical host virtualized into several small hosts, in which CPU and memory are shared by * * * *, and sometimes there may be dozens or hundreds of VPS on a machine. Once this physical host hangs up, all the VPs on it will suffer, and the performance is often not guaranteed.
Cloud server: A cloud server is a huge server array. After load balancing, many virtual hosts are born, and each server in the cluster has a mirror image of the cloud host. Unless all the servers in the cluster have problems, the cloud host will be inaccessible. So data security and performance are basically guaranteed. Moreover, on the cloud host, IP, CPU and memory are isolated, so there will be no situation where everyone grabs memory and no one can run.
Dedicated/Independent Server: It is a real server/host. This host is independent and only for its own use. You can ask the server to replace the hard disk and memory, and there will be no second person occupying your resources.
