Cloud servers and virtual hosts are two different hosting solutions. The differences between the two are mainly reflected in resource isolation, scalability, flexibility, reliability, and security. The details are as follows:

Resource isolation: In cloud servers, each virtual machine has independent resource allocation, including processors, memory, and storage space, so the resources among them are isolated from each other. The virtual host is to divide multiple virtual hosts on a physical server through virtualization technology, and they share the resources of the server.

Scalability: Cloud servers usually have higher scalability and can dynamically adjust and expand resources as needed. You can quickly increase or decrease cloud server resources according to traffic changes to meet the needs of applications. The resource allocation of the virtual host is relatively fixed, and the scalability is low.

Flexibility: Cloud servers provide more flexible configuration options, and you can freely choose the operating system, hardware configuration, and software environment to meet the specific needs of the application. Web hosting usually offers more standardized configuration options with relatively few choices.

Reliability and high availability: Cloud servers usually provide high availability and reliability through technologies such as load balancing and failover, so that even if a failure or server failure occurs, your application can continue to run. The reliability and high availability of web hosting often depends on the stability and backup measures of physical servers.

Security: Cloud servers typically offer higher levels of security measures, such as firewalls, data encryption, and authentication, to protect your applications and data. The security of virtual hosting depends on the security configuration and management of the server.

Cost: Usually, the cost of cloud servers will be relatively high, because you pay for the amount of resources you actually use. Web hosting costs less because you share server resources and usually pay for a fixed plan fee.

In conclusion, if you need a higher level of resource isolation, scalability and flexibility, as well as higher reliability and security, cloud servers may be more suitable for your needs. If you have low resource needs and a limited budget, web hosting can be an affordable option.
