Virtual Private Server (VPS) is a virtualization technology that allows the creation of multiple independent virtual server instances on a single physical server, each of which can run its own operating system, applications, and resources. This virtualization technology typically uses the following virtualization architectures:

Full Virtualization:

This approach to virtualization creates one or more virtual machines (VMS), each of which is treated as a separate physical computer that can run a different operating system. In full virtualization, the operating system of a virtual machine interacts with the hardware of a physical host through the virtual Machine monitor (Hypervisor). Hypervisor Manages VM resource allocation and device simulation.

Common full virtualization hypervisors include:

VMware vSphere/ESXi

Microsoft Hyper-V

Xen

Para-virtualization:

Paravirtualization is also a form of virtualization, but unlike full virtualization, paravirtualization requires some modification of the operating system in the virtual machine in order to communicate more effectively with the Hypervisor. This can reduce some of the performance overhead associated with virtualization.

Common paravirtualization hypervisors include:

Xen

Containerization:

Containerization is a more lightweight virtualization technology that differs from traditional virtual machines by isolating different applications at the operating system level. Each container runs on a shared kernel of the host operating system, so containerization can make more efficient use of resources. Each container contains its own application and runtime environment, but they share the kernel of the host operating system.

Common containerization techniques include:

Docker

Kubernetes

These virtualization technologies have different advantages and disadvantages, and which one you choose depends on your needs. For example, if you need to isolate different operating systems, full virtualization may be more appropriate; If you want to run multiple applications more efficiently, containerization may be a better choice.
