Today's cloud is very popular, low prices, strong cloud functions, so that everyone moved unceasingly, however, because of the domestic service provider clutter, so that some service providers to fake, so that users buy is the cloud host, with the real cloud is not the host but VPS, technology let a server added a cloudy host shell, Make it appear to have some cloud characteristics.

In the end what is the real cloud host? How can users tell the following general three points to make you see clearly:

First, look at the cloud host backup strategy. The real cloud host is a snapshot strategy that supports the online one-key recovery system and the original state of the data, which is unmatched by traditional backup.

In other words, user data is lost or mistakenly deleted, only need a key to restore it, just as the PC image recovery, do not need to be like the traditional IDC mainframe, through the custodian of the administrator, the data back out, restore and then re-import back to the server, which is completely different from the two concepts and technologies.

Second, look at the host resources. The real host resource is the exclusive hardware and bandwidth resources that are never shared with others. The VPS host will generate resource contention, because these are multiple hosts that are virtualized on the same server, and the resources on a single server are capped, it is not natural to have "inexhaustible" computing resources for small and medium enterprise users, as is the case with thousands of server clusters of resource pools.

Finally, look at the underlying architecture. The real cloud host is based on a huge cluster of servers, and the architecture of Hyper-V and VMware is based on a single physical machine and cannot support clustered clouds. For example, if it is a cottage cloud host, it is very likely that a single point of failure, which in the real cloud host does not exist. Similarly, when the user needs to upgrade the cloud, the real cloud host to support the smooth upgrade, and the cottage cloud host needs to first of the server data export to make a backup, in order to upgrade.

Many unscrupulous manufacturers in order to make money, and there is no real cloud host technology, with this duplicity technology circle of money, in the detriment of the interests of users, but also damage the healthy development of the entire market. Therefore, users in the purchase of cloud host need to polish their eyes, as far as possible choose to have a brand name IDC service providers (such as eight-degree network), do not fall into the merchant "ultra-low price" trap.
