What is cloud hosting and what is the difference between cloud server and vps? 

[There are a lot of cloud servers in the market now, what is a real cloud server? ]
In essence, the front-end hardware and data storage of the server are separated, and the technical implementation has something in common with VPS, but it is not exactly the same.
Cloud hosting integrates high-performance servers and high-quality network bandwidth to achieve the separation of storage and computing, and truly seamless switching, which is different from ordinary VPS that only physically isolates one host. Therefore, the data security and full operating conditions of the real cloud host are the highest among all host products, effectively solving the traditional host hardware failure, data loss and other drawbacks, and achieving cost savings, can fully meet high reliability, Manageable needs. Cloud hosting is a new direction that can replace existing servers. 

[What is the difference between cloud server and vps] Regarding the difference between cloud host and VPS, we can discuss the following six aspects:
1. From a technical point of view: cloud host uses cloud computing technology, and cloud computing technology integrates Various software and hardware technologies such as computing, network, storage, etc. For VPS, it simply uses virtualization software technology, which is relatively backward compared to the high standards of cloud computing technology;
2. From the perspective of security: cloud hosts have natural protection against ARP attacks and MAC spoofing , snapshot backup, data will not be lost forever. VPS does not have this function;
3. In terms of reliability: cloud hosting is based on server clusters, so the hardware redundancy is high and the failure rate is low; while VPS is relatively less hardware redundant, The failure rate is high;
4. From the perspective of flexibility: users can add their own configuration online in real time, and the expansion space is large; while VPS has limitations in this regard;
5. From the perspective of performance: cloud hosting It is 4 times the computing power of the same configuration independent server, which can meet the requirements of high-performance computing; while the computing power of VPS is only a part of the independent server;
6. From the perspective of isolation: the cloud host adopts hardware isolation, which is completely isolated from each other. Does not affect; VPS uses software isolation, which has a greater impact on each other
