What kind of service is a CVM? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.
CVM is a WEB-based service that provides elastic cloud technology with adjustable host configuration, Iaas services that integrate computing, storage and network resources, and CVM leasing services with the ability to use and pay on demand.
CVM is a kind of virtualization technology similar to vps server. VPS uses virtual software. VZ or VM virtualizes multiple parts similar to independent servers on one server. Each part can be used as a separate operating system, and the management method is the same as the server.
On the other hand, a CVM virtualizes multiple independent servers on a group of cluster servers, and each server in the cluster has an image of the CVM, thus greatly improving the security and stability of the virtual server. unless all the servers in the cluster have problems, the CVM will not be accessible. It has been greatly improved in flexibility, controllability, expansibility and resource reusability.
CVM is a computing service with flexible processing capacity, and its management method is simpler and more efficient than physical servers. CVM helps you quickly build more stable and secure applications, reduce the difficulty of developing OPS and the overall IT cost, and focus more on the innovation of core business.
The hardware facilities of CVM are higher than ordinary servers, with dedicated routers, hardware firewalls, hardware storage servers, two management servers and so on. First of all, the server needs memory, hard disk, CPU. To form a server. On the other hand, all the resources required by the CVM are put into a large resource pool, which can be extracted on demand, and all the resources are proposed as a server.
If an ordinary server, if the hot backup machine also has problems, resulting in data loss, no way to transfer, and the cloud server can avoid this, a server at least more than 8000 plus hosting, a total of at least more than 10,000 to get a server, while the lowest rental price for a cloud server is only a few dozen yuan per month.
This is the end of the answer to the question about what the CVM is. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
