I believe that friends engaged in the Internet have more or less heard of cloud server. In fact, this is a cloud host. We often hear that servers, virtual hosts and VPS are similar in nature, mainly for enterprises and personal websites. If the probability of cloud weapon is not clear, it can also be simply understood as an advanced network U disk, and its use is actually the same.
What is cloud server? In fact, this is on the cluster server. In addition to different independent hosts, it is virtual. In this way, each host will have a cloud host image, which can greatly improve the security and stability. In other words, once the service fails, the entire virtual machine will not be affected. Unless all the hosts fail at the same time, there will be no access. It can also be seen that the virtual machine has the characteristics of affordable sharing, and the resources are exclusive.
In the selection of cloud server, the first thing to pay attention to is the expansion problem. Because this is a multi server cluster, we must consider whether the service provider has the advantage of expansion. Compared with other servers, the advantages of virtual machine are zero down payment, deposit and maintenance. Based on this advantage, many people choose, so avoid choosing some service providers that require you to pay down payment and maintenance fees.
