Virtual Server

A virtual server is a technology that allows multiple independent server environments to be created by dividing the resources (CPU, memory, storage, network, etc.) of a physical server. This enables running multiple virtual servers (VPS - Virtual Private Servers) on a single physical machine.

Here are some key features of virtual servers:

1. Independent Operation: Each virtual server operates independently with its own operating system, applications, and configurations. It can be isolated from other virtual servers.
2. Resource Sharing: Multiple virtual servers run on a single physical server, and the resources (CPU, RAM, disk space) are shared among them. However, each virtual server has a dedicated amount of resources.
3. Flexibility: The specifications of virtual servers can be easily changed. For example, additional RAM or processing power can be added as needed.
4. Cost Efficiency: Virtual servers provide a more efficient use of resources, reducing costs. Instead of purchasing separate hardware for each server, multiple virtual servers can run on a single physical server, saving costs.

Virtual servers are commonly used for web hosting, application hosting, testing and development environments, security isolation, and many other purposes.
