One way of Thai embarrassed embarrassed at the end of 2012 under the bed to the Chinese film box office record, but also refresh the record. But in IT, data center security failure events erupt frequently, also the impact of enterprise user's psychological line of defense in a meeting. Only look, the security problems of the data center, don't be embarrassed again. "Tai embarrassed".
Cloud computing service is touted to be the IT saints in this era, all services can be "cloud". However, when many companies to be the first to eat crab, but found that often the most vulnerable is their. In recent years, emerge in an endless stream of cloud services broken network events, so that the industry could appall.

People gradually return to the ideal, to more clearly see the true face of cloud computing. It can be said, no matter how lofty dream or to find a secure foothold, cloud services eventually from one data center to be transmitted to a data center, and in the process still could not escape the need, computer, network, power, storage, etc. between collaborative work. As a result, the entire process error and loopholes in the offing, coupled with natural disasters. So, enabled cloud services, you must have a certain amount of mental preparation, but also with a second-hand solutions to deal with.

Editor here, look at the reasons behind a series of broken network events that occurred in recent years. Between from 2009 to 2012. Perhaps make you see: even if the computer error seems inevitable, reinsurance measures seem only security event control in a small probability range.

The off network types: system failure

In fact, the diesel has become the lifeblood of the data center recovery, to take over the entire load as a backup power system, prompting the special measures to keep the generator fuel. With the immediate focus gradually shifted to the post-disaster reconstruction, we need long-term engineering and disaster recovery data center location, explore this topic may last for months, or even years.

Shengda Yun has to make every effort to assist the user to recover data.

Lead to individual users' data lost because of a physical server disk is damaged, Shengda Yun technicians are given their own interpretation: the virtual machine's disk, there are two modes of production, a direct host the physical disk. This case, if the host's physical disk fails, the cloud host will inevitably result in the loss of data, which is generated by the incident reasons; another is to use remote storage is grand hard disk products, this way the actual is to save the user's data to a remote cluster, and at the same time do multiple backups, and even host a failure will not affect a the Cloud host of data. Difficult to avoid because the physical damage to the machine, in order to avoid accidental loss you are experiencing, we recommend that you also do data backup to cloud host.

Summary

Enable cloud services company, a large extent, is considering such a service can be more editing, cost-effective. However, such considerations if it is based on reducing the cost of security as, it is estimated that the boss will not agree with a lot of companies. Cloud services off the endless stream of events caused by concerns about the safety of the cloud.

Now, the solution can proceed from several angles, sure cloud services for enterprise-class customers, regular backups of the data of the cloud, with the second set of solutions, in order to prepare for contingencies. For cloud service providers, since a variety of off-network event is inevitable, it must consider a countermeasure to minimize the loss of their users, improve response efficiency off network events.

Government departments have responsibilities of oversight and remind legal legal cloud services were introduced and constantly improve, and to remind the user to one hundred percent reliable cloud computing services do not currently exist.
