The concept and advantages of cloud host analysis

Cloud computing is hailed as the fourth revolution in information technology.

Cloud hosting services based on cloud computing have become the first choice for many site users.

Cloud host is an important part of cloud computing in infrastructure applications, virtual out of a group of cluster hosts similar to a separate host, each host in the cluster will have a mirror of the cloud host, in order to improve the security stability of the host. Simply put, unless all the hosts in the cluster have problems, the cloud hosts will not be able to access them.

IDC, which provides cloud hosting services, makes a "cloud" of hardware and network lines, giving customers some network interface APIs to the cloud. Because there are many servers in the cloud, each customer is not sharing a server, but all the servers.

Cloud Host Advantages:

Cloud hosts use cloud computing technology, while cloud computing technology integrates computing, networking, storage and other software hardware technologies. Standalone hosts, these resources are not consolidated.

Cloud hosts have natural anti-ARP attacks and Mac spoofing attacks, snapshot backups, and permanent data loss. The standalone host does not.

The cloud host is based on the server cluster, so the hardware redundancy is high, the failure rate is low, and the independent host is relatively less hardware redundancy.

Users can increase or decrease their own configuration in real-time, scalability, and the independent host is a big limitation in this area, there are new applications, can only buy another server.

From a stability perspective, the cloud host can fail to automatically migrate, if one cloud host fails, the above application will automatically migrate to other cloud hosts, and the standalone host does not exist.

From the perspective of energy saving, cloud host based on cloud computing automatic transfer technology, that is, the night, the physical server utilization is not high, automatic migration technology will put the application into several physical servers, other physical servers can go into hibernation, so that energy saving.
