A VPS or Virtual Private Server is a type of hosting service that provides a virtualized server environment within a larger physical server. Simply put, a VPS is a part of a physical server that is divided into multiple virtual servers, with each virtual server acting as an independent private server for the user. This virtualization technology allows multiple users to run isolated server environments on the same physical hardware.

The main features and functions of VPS hosting are:

insulation:
Each VPS operates independently with dedicated resources such as CPU, RAM, storage, and network connectivity. This isolation ensures that the performance of your VPS is not directly affected by the activities and configurations of other VPS instances on the same physical server.

Special resources:
VPS users are allocated resources reserved exclusively for their virtual servers. This ensures more stable and reliable performance compared to shared hosting, where resources are shared among multiple users.
