However, for memory and CPU, unlike a shared server, the performance of the guest virtual machine operating system is safe, so it is more suitable to use than shared servers. More load on the server. In addition, another difference from a shared server is that you can freely operate software on the client operating system.

Therefore, dedicated servers are more compatible with performance and load. Additionally, if that physical server fails, all VPS users using that server will be affected.
