Traditional server and cloud server are the two mainstream server choices nowadays. Cloud servers are especially popular now, and more and more people are using them. However, cloud servers are not perfect and also face some problems.
1. In terms of price, cloud servers are relatively cheaper when purchasing in the early stage, but the servers are relatively long-lasting. If they need to be used for a long time, the physical server is still relatively cost-effective.
From the perspective of data security, the physical server is more controllable and some problems can be solved by themselves, but if the cloud business fails, it will be difficult to solve them by themselves.
2. Relying heavily on the network, security is difficult to ensure
As we all know, cloud servers rarely experience downtime, but cloud servers are based on WEB management model and rely heavily on the network. WEB applications have been considered to have potential security risks for a long time.
may be disastrous if it encounters high-level hacking attacks. Top overseas DNS service providers have been seriously hacked. Whether ordinary cloud service providers have complete and powerful attack protection capabilities is also a major test that cannot be ignored.
3 and Because public cloud hosts are virtualized, there are some disadvantages of virtualization technology itself, such as the high host load, which will affect the cloud host on it.
, and the model configuration is generally the general version, which cannot meet certain special hardware or system configurations. Overall, the advantage is that it is cheap and flexible, and the disadvantage is that its performance is average and cannot meet certain particularly personalized configuration requirements.
In short, although cloud servers have their shortcomings, their advantages are also very obvious. You can learn more about it when choosing and balance your choice.
