1. Technically, the cloud server adopts cloud computing technology, which integrates various software and hardware technologies such as computing, networking and storage. Independent servers are independent and will not integrate these resources.
2. In terms of security, the cloud server has natural protection against ARP attacks and MAC spoofing, and the snapshot backup will never lose data. Independent servers do not have this feature;
3. In terms of reliability, the cloud server is based on server cluster, with high hardware redundancy and low failure rate; The independent server has less hardware redundancy and high failure rate;
4. Flexibility: users can add their own configuration online in real time, which has a large expansion space; On the other hand, independent servers have limitations in this respect. If there is a new application, you can only buy another one.
5. From the performance point of view, the cloud server is four times the computing power of the independent server with the same configuration, which can meet the requirements of high-performance computing;
6. From the point of view of stability, a cloud server can be automatically migrated if it fails, which means that if a cloud server fails, its application will be automatically migrated to other cloud servers. Stand-alone servers do not have this feature. If they fall, they will fall.
7. From the point of view of energy saving, cloud server is an automatic migration technology based on cloud computing, that is to say, at night, the utilization rate of physical servers is not high, and automatic migration technology will concentrate applications on several physical servers, and other physical servers can sleep, thus saving energy.
