Is it better to choose a CVM or a server? In the era of non-cloud computing, usually each tenant or enterprise needs to build their own data center or rent the operator's hardware and infrastructure for their own service computing and data storage, which is more expensive.

After using the CVM, enterprises or tenants can lease computing resources, network resources, and storage resources from operators that provide cloud computing, instead of leasing hardware and infrastructure, thus simplifying or eliminating the need for self-building and self-maintenance data centers.

In addition, the data centers of cloud computing operators are more complex and large. One of the applications is to support multi-tenancy. CVM supports multi-tenancy at the same time mainly as follows:

(1) Rapid configuration and deployment for each tenant's business

The resources that each tenant applies for from cloud computing operators need to be able to quickly and automatically enable in the data center network, including the corresponding configuration of firewalls, IPS/IDS, LoadBalancer and other devices to achieve plug and play.

(2) Traffic isolation between tenants

In fact, because tenants may share hardware equipment, bandwidth, storage and other resources, in order to ensure security, in the data center dominated by layer 2 network, the traffic between tenants needs to be isolated to prevent the traffic of tenant A from being received by tenant B. The traditional traffic isolation method of layer 2 network based on VLAN (Virtual Local area Network) is limited by the number of 4096 VLAN.

(3) the network configuration is decoupled from the configuration related to the tenant application.

Therefore, the technology of CVM is more advanced than that of traditional server, and it is more suitable for ordinary users to choose. The above is about whether the cloud host or the server is good.
