Introduction and analysis of VPS technology

The VPS is called Virtual Private server, which is known as VM, which GoDaddy calls dedicated server, VDS). It is the use of a variety of virtualization means of a single physical server virtual server for multiple virtual servers to provide users with. The difference between VPS is mainly the implementation of virtualization technology is different:

Common virtualization technologies under Linux platforms

• OpenVZ Introduction
• Introduction of Xen Virtualization Technology
• Overview of KVM Virtualization Technology
• Vmware

Common virtualization technologies under the Windows platform

• Hyper-V
• Vmware

From the degree of virtualization, OpenVZ is the operating system level (Operating System-level Virtualization) virtual products, and FreeBSD Jail,solaris Zone, Linux-vserver and other similar; Products such as Xen and vmware,kvm,hyper-v stand in the same camp. The OpenVZ VPS actually provides a virtual environment/ve, also known as a container (Container), while the Xen VPS provides a hypervisor-based virtual machine (Vsan), This is essentially different. From the price of VPS service providers, the average openvz price is lower than other types of virtualized VPS prices.

What is the best VPS performance for that technology? Is the performance of OpenVZ the weakest?

Not necessarily. OPNEVZ service Providers if not oversold, performance is more powerful than other types of VPS (for example, no oversold 128MB Openvz VPS can run Yum update, but 128MB Xen VPS does not necessarily go through Yum update). As long as the VPS provider dares to provide the OpenVZ hen's monitor state diagram, you can see the current hen on the memory surplus and system load, roughly can determine whether there is oversold.
