Analysis on differences between Vm instances and VPs in 92cloud

Cloud hosting solutions integrates IT infrastructure capability leasing services for computing, storage, and network resources, it can provide on-demand and On-Demand Server rental services based on the cloud computing model and can be seen as a new generation of shared hosts. VPS (virtual private server), using the advantages of virtual service VPs software to create multiple isolated small servers on a physical server, these small servers themselves have their own operating systems, its operation and management are exactly the same as those of an independent server. VPs ensures that all resources are exclusive to users, so that users can enjoy the service quality of independent hosts at the price of virtual hosts. As a whole, the difference between Vm instances and VPS hosts is not very big. It can be said that VM instances are similar to more advanced VPs host products. However, there is a difference between the two in terms of product reliability, elasticity and performance, time deployment, and cost.

In general, the security and reliability of VPs are worse than those of VM instances. program defects, ARP spoofing, viruses, and resource congestion installed on other VPs instances on the same physical server will seriously affect the security and reliability of VPs, basically no defense capability for ARP, Trojan and DDoS. The cloud host has built-in ARP protection to improve the anti-DDoS capability in a large scale.

In terms of elasticity and performance, the performance is average and only applicable to small-scale concurrent access. The performance is not guaranteed and is vulnerable to the extrusion of other VPs on the same physical server. The VM instance has good and guaranteed performance, the effect can be equivalent to that of a physical server. At the same time, the cloud host can truly obtain the root permission. Users can reinstall and upgrade the operating system, while the VPs host user does not have the root permission and cannot reinstall or upgrade the operating system.

In terms of supply and time deployment, Vm instances can be deployed in just a few minutes, and the operating system can be independently installed with one click.

In terms of cost, Vm instances are available in real time and can be scaled as needed, without the need to pay for the original resources. Basically, there is no maintenance. You can also share the cost advantages brought about by scale, green energy saving, and Best IT practices; although the price of VPs is low, its performance and security are not as guaranteed as those of VM instances.

In view of the differences between the two, you can compare the advantages and disadvantages of the two based on your needs to choose the most suitable host.
