First of all, since VPS is an independent system, it can be regarded as a quasi-independent server, so the restrictions of IIS, etc., are completely controlled by the landlord himself.

Secondly, the performance of VPS is determined by the following aspects: first, as a virtual technology, the implementation of VPS has a variety of technologies, and I personally recommend that you use VM or VS technology to achieve VPS, and the stability of VZ technology is poor, and the genuine 64-bit can be considered, but there are problems with software compatibility. Because the first two technologies are hardware virtualization, and the latter is kernel virtualization.

Second, VPS as a server product is inseparable from the bandwidth line, so the landlord has to test the bandwidth after getting the test machine. Third, whether the 256M memory can be determined by the application you want to do, just like the configuration of the computer, what program you use, what database you use, and how much access you have, is the premise of determining your configuration.

Finally, I hope that the landlord will ask clearly that some machines are the technical implementation of VZ, and some are other technologies, you say hello, and then decide...

In addition, hardware virtualization technology is actually virtual not only memory but also hard disk, CPU a complete set of hardware environment, so VM vs VPS can be compatible with a variety of systems on the same host. But vz is basically when everyone shares the system, and one host cannot support multiple systems, for example, if you use 256 memory, when you are not satisfied, others can also use it. Therefore, it is recommended that you use hardware virtualization technology to implement VPS

Many people don't know what VPS is, let's find out together.

Introduction to VPS

VPS is the English abbreviation of Virtual Private Server VirtualPrivateServer, and VPS technology is a high-quality service that divides a server into multiple virtual dedicated servers. The technologies that implement VPS are divided into container technology and virtualization technology.

Uses of VPS

In a container or VM, each VPS can be assigned an independent public IP address and an independent operating system to isolate disk space, memory, CPU resources, processes, and system configurations between different VPs, simulating the experience of exclusive use of computing resources for users and applications.

VPS can reinstall the operating system, install programs, and restart the server separately just like a standalone server. VPS provides consumers with the freedom to manage configurations, which can be used for enterprise virtualization or IDC resource rental. IDC resource leasing is provided by VPS providers.

The experience of using VPS is also quite different due to the differences in the hardware and VPS software used by different VPS providers and the different sales strategies. In particular, VPS performance will be greatly affected when the VPS provider is oversubscribed and the physical server is overloaded.

Relatively speaking, container technology is more efficient than virtual machine technology, and it is easier to oversell, so generally speaking, container VPS is higher than that of virtual machine VPS. And VPS is a server with a public IP. Do you understand?
