With the rapid development of Internet, great changes have taken place in people's lives. It has an imperceptible influence and change for our generation who are in the information age. The characteristics of the Internet will be a good integration of our resources, so that many things are no longer limited, to sum up, there are three major characteristics: extensive resources, communication, communication.
Practice has come to know that the people who first went deep into the Internet industry have now tasted the sweet fruits, and some successful people in traditional industries have begun to focus on the advantages of the Internet. In the next five years, the Internet will enter a stage of rapid development. In these five years, anything is possible, depending on how you view and choose.
VPS host, a high-quality service that divides a server into multiple virtual proprietary servers, is a product between independent servers and virtual hosts. Each VPS can be assigned an independent public network IP address, independent operating system, independent super-large space, independent memory, independent CPU resources, independent execution programs and independent system configuration, etc. In addition to assigning multiple virtual hosts and unlimited enterprise mailboxes, users also have independent server functions, which can install their own programs and restart the server separately.
CVM is virtualized on the basis of server cluster. The server operator makes its hardware and network lines into a "cloud" and then provides some network interface API to the "cloud" for customers to use. At this point, each customer no longer shares a particular server, but all the servers in the cloud.
We can discuss the difference between a CVM and a VPS host from the following six aspects:
1. Supply and deployment time
CVM-in real time, it can be completed in a few minutes, and the operating system can be deployed or installed independently.
VPS- has a real-time, independent operating system.
2. Safety and reliability
CVM-High: built-in ARP defense to enhance DDOS anti-attack capability on a large scale; share the performance and reliability of brand enterprise-class servers and hardware virtualization. Built-in HA; provides backup, snapshot, data backup and other fast recovery measures.
VPS- is high: program defects, ARP spoofing, viruses and resource congestion installed on other VPS on the same physical server will seriously affect yourself; basically no ARP, Trojan and DDOS prevention capabilities.
3. Performance and guarantee
CVM-good, good and guaranteed: same as physical server.
VPS- is better: the performance is OK, and it is only suitable for small-scale concurrent access; the performance is not guaranteed and is vulnerable to the squeeze of other VPS on the same physical server.
4. Elasticity and scalability
CVM-immediate supply, on-demand expansion, no need to pay for the original leased resources.
The rapid expansion of VPS- is limited by the configuration of a single server.
5. Cost of ownership
CVM-the overall cost is low.
VPS with low configuration of VPS- has the lowest rental price.
6. Easy to use and easy to manage
CVMs-built-in KVM, customers can centrally manage distributed CVMs through the self-service system, and have full root or Super Admin operating system permissions.
