The difference between vps and cloud servers:
1. Infrastructure determines the difference in performance: First of all, we need to understand a concept, that is, the performance of VPS is limited by its own location If there is a problem with the physical server, the VPS will also have problems, and the website on it will also be affected. The cloud host is built on a cluster server, and a problem with one server does not affect the operation of the cloud host.
2. Different storage models: Since cloud hosts are based on cluster servers, they use network distributed storage. VPS stores data on the hard drive of a local physical server. Only one copy of the data is stored. Once damaged, it cannot operate normally. This is the essential difference between cloud hosting and VPS.
3. Different reliability: Cloud hosts are supported by multiple servers, which can achieve hotspot migration and automatic switching of failed nodes. The reliability is much higher than that of VPS. VPS cannot do this because it is limited to a single server. When the server needs to be upgraded or restarted, the operation of the cloud host will not be affected, ensuring the normal operation of the website. VPS, on the other hand, needs to be interrupted and cannot continue to operate until the server is restored, which is a waste of time. When a computing node fails, the cloud host can automatically switch to other nodes without any impact, while the VPS can only be interrupted, which may also cause data damage.
4. Different support for intranet and mirroring: cloud host naturally supports intranet, data transmission speed is extremely fast on intranet, which is conducive to load balancing, and cloud host can also quickly clone multiple system images . Due to differences in architecture, it is difficult for VPS to support the intranet, and it does not support custom images.
5. Different upgrade methods: Because cloud hosts are virtualized and exist in the network, they can easily expand in-situ and upgrade bandwidth, hard disk, CPU and other configurations, while VPS itself is limited by the host machine. , limited expansion capabilities. In terms of upgrade time, cloud hosts can be completed online within a few minutes and are fully automated, while VPS takes longer.
In addition to these aspects, the difference between cloud hosting and VPS is that cloud hosting is superior to VPS in terms of hard disk I/O reading speed, configuration time and adding independent IP, which is more beneficial to website access.
We can imagine the cloud host as a well-trained department and the VPS as an individual soldier. During combat, a well-trained unit and comrades can support each other and play a greater role than the whole Additive effect. An individual soldier can only rely on himself, and his execution effect is limited by his own quality, and he is certainly not as good as an army. This is the image of the difference between cloud hosting and VPS.
