Both cloud hosting and cloud virtual hosting are very popular cloud products in the past decade. With the continuous advancement of cloud computing technology, the traditional IDC service has become less and less.
For individuals and enterprises, both cloud servers and cloud virtual hosts can be used to build websites, but what is the difference between cloud servers and cloud virtual hosts? How to distinguish between the two? How to choose? Therefore, conceptually speaking, cloud servers and cloud virtual hosts are essentially different. In the VPS era, using virtualization technology, a physical server can be divided into multiple virtual machines, and there are few solutions for multiple physical machine clusters. The emergence of cloud computing technology has brought clustering to the extreme and greatly improved the reliability of services, while the distributed storage concept has improved the reliability of data, and a new era of virtualization has arrived. Cloud means cloud computing, and cloud server is the most basic product in the cloud computing era. Cloud host (ie, cloud server) is an important part of cloud computing in infrastructure applications. It is located at the bottom of the cloud computing industry chain and its products are derived from cloud computing platforms. The platform integrates three core elements of Internet applications: computing, storage, and network, and provides users with public Internet infrastructure services. A cloud host is a group of cluster hosts that virtualize multiple parts that are similar to independent hosts. Each host in the cluster has an image of the cloud host, which greatly improves the security and stability of the virtual host, unless all hosts in the cluster If all problems occur, the cloud host cannot be accessed. A virtual host is a specific application environment (such as a WEB application environment) built in a physical server to become a dedicated server, and a cloud virtual host is a virtual host deployed on a cloud server, such as a silicon cloud virtual host. Different features Cloud servers generally have independent IP addresses and must have independent operating systems, which can be remote desktop management (Windows) or SSH connection management (Linux). You can install any software or service you need, including making a website, which is very versatile. Cloud virtual hosts generally share IP, and one IP is used by many people. Of course, there are exclusive IPs, such as silicon cloud exclusive cloud virtual hosts, which are slightly more expensive. The user has only FTP-like management authority, and cooperates with the web panel provided by the manufacturer to manage the website, thereby uploading management files, and doing some website application configuration. The virtual host cannot install software by itself, it is installed and configured by the manufacturer. Generally, you can only put websites or store information.
The detailed characteristics of the two are not described here. We can refer to the instructions of some manufacturers. For more detailed instructions, please refer to: detailed description of cloud server, detailed description of cloud virtual host .
Is security different?
Many people think that cloud servers are more secure than virtual hosts, which I cannot agree with. Because this needs to be divided into scenarios.
First of all, a cloud server is a server with an independent operating system. No matter how secure the cloud manufacturer is, there are vulnerabilities caused by the user’s own lack of technology, such as port, program use, operational failure, etc., while cloud virtual hosts are caused by The website server environment customized by cloud vendors will deal with many security issues. The only unsafe place is the user website code.
