Today, I will take you to understand cloud hosting. "Cloud hosting" can be regarded as a new generation of hosting services. First, the host company makes its hardware and network lines into a "cloud", and then provides some network interface APIs leading to this "cloud" for customers to use. At this time, each customer is no longer sharing a specific server, but all the servers in the cloud. It integrates high-performance servers and high-quality network bandwidth, effectively solving the problem of high rental prices and uneven service offerings for traditional hosts. The shortcomings such as unevenness can fully meet the needs of small and medium-sized enterprises and individual webmaster users for low-cost, high-reliability, and easy-to-manage hosting services.
1. In terms of technology: cloud servers use cloud computing technology, and cloud computing technology integrates various software and hardware technologies such as computing, network, and storage. The independent server is independent and will not integrate these resources.
2. In terms of security, the hardware level can be used to isolate faults and security. The platform has built-in ARP attack protection capabilities, distributed and large-scale to enhance the ability to prevent DDOS attacks, while independent servers do not have this function;
3. In terms of reliability: cloud servers are based on server clusters, so the hardware redundancy is high, and the failure rate is low; while independent servers have relatively less hardware redundancy and high failure rate;
4. From the aspect of flexibility: users can add their own configurations online and in real time, with a large expansion space; independent servers have limitations in this regard. If there are new applications, they can only buy another one.
5. From a performance point of view: cloud server is 4 times the computing capacity of an independent server with the same configuration, which can meet the requirements of high-performance computing;
6. From the point of view of stability: Cloud hosting is an upgraded version of VPS, which can also be understood as a virtual server. It is divided into multiple parts similar to independent hosts on a group of cluster servers. Each machine in the cluster will have A mirror backup of the cloud host. When one of the machines fails, the system will automatically access the backups on the other mirrors.
