In order to help you solve this problem, many beginners are not very clear about what is the solution to the exception of CVM and CVM in the United States. the following editor will explain it in detail for you. People with this need can come and learn. I hope you can get something.

It is critical to choose a high-quality server when building a station, but in the process of practical application, some users may choose blindly, resulting in server anomalies that often occur when they are in use. it brings a lot of trouble to the normal operation of the website. In fact, for some common server exceptions, the solution is relatively simple, so how to solve the CVM / CVM exception in the United States?

Solutions to CVM / CVM anomalies in the United States

In the final analysis, the infrastructure services provided by cloud servers are based on physical data center physical hardware virtualization. Therefore, the reliability of physical data center facilities is the basis for ensuring the stable and sustainable operation of the cloud platform. How to solve the anomaly of CVM in the United States, first of all, from the redundant design of power and network to the plan of serious accidents such as earthquake and flood, are all problems that CVM providers should consider and solve. Secondly, disaster recovery needs to be physically isolated from multi-node data centers. In the event of some unpredictable physical disasters such as floods, earthquakes, or the network paralysis of large-scale operators, the cloud can suspend the affected regional computer rooms. Disaster recovery data center quickly takes over all or part of the key business originally running in the main data center.

At present, many large-scale American cloud host vendors are equipped with multiple clusters in the data centers of each region. User data are distributed in different servers in different clusters, and different clusters are active and standby to each other. If the service of a cluster is interrupted, the cluster will suspend the reading and writing of the data, retain the exception site, write and migrate the data to other clusters in the same room, and automatically repair the logic module or storage module within the cluster. If the automatic repair of the cluster fails, the Bluehost on-site operation and maintenance personnel will intervene manually to repair the hardware failure. During the repair process, users can continuously obtain data from other health clusters, and the service is steadily available.

As for how to solve the exception of CVM in the United States, the above are some simple solutions, hoping to help the majority of users. Generally speaking, the cloud server platform supports multi-level disaster recovery capability, and its running ability is still very strong. In the process of practical application, it is suggested that it is best to ensure the correct operation and do a good job in disaster recovery from all aspects, so as to ensure the real-time availability of business services.
