This article lets you know how to distinguish virtual hosts

For new webmasters who are going to build a website Virtual machine (ECS), these terms are confusing. So what's the difference between the three?

1、 Virtual machine ("virtual space" or "space")

The virtual host also divides a server into several virtual exclusive use spaces. However, the spaces cannot be customized, only support specific functions, and all use a single IP address. More importantly, the spaces affect each other, including the CPU, memory, and disks. Intuitively, a server is divided into multiple spaces, and then multiple users use server resources together. Generally, it supports a variety of site building environments by default, and users can upload and install the site building program directly. Because the virtual machine space does not support connecting to the desktop for other operations, the general server tenant will provide a control panel for simple operations such as domain name binding and file decompression.

2、 VPS host

VPS The host uses the VPS (Virtual Private Server Virtual Private Server) technology, a high-quality service that divides a server into multiple virtual exclusive servers, that is, a real host is virtualized into multiple small hosts. each VPS All can be assigned independent public network IP addresses, independent operating systems, independent space, independent memory, independent CPU resources, etc., and can be remotely connected to the desktop, which is equivalent to a fully functional computer. In addition to being able to allocate multiple virtual hosts and unlimited corporate mailboxes, users can also change the operating system, install programs, deploy the environment, and restart the server according to their needs, in other words VPS Compared with the virtual host, the host has a higher degree of freedom.

3、 ECS

I believe you will often hear about Alibaba Cloud, Tencent Cloud Amazon Cloud But what do these clouds mean. You can roughly understand the cloud in the Internet as a cluster. A single server cannot form a cloud, and the computing power of a server is always limited. Building more than N servers into a cluster through cloud technology can theoretically provide unlimited computing power.

The ECS product has the characteristics of high availability, reliable data, high performance and elasticity through the advanced and mature disaster tolerance redundancy architecture at the bottom, which can significantly reduce the cost of early business deployment and subsequent operation and maintenance. for example Amazon Cloud Science and technology provides a series of rich cloud services, including computing, storage, database, artificial intelligence, Internet of Things, security and other fields.

4、 Summary

Virtual machine: It's like sharing a suite. A house separates more than N rooms. The rooms only have basic beds, stools and other personal things. However, toilets, kitchens, washing machines and so on are all used by the public, which has an impact on each other.

VPS: It's like a one floor apartment. There are N separate rooms, but the rooms have toilets and washing machines. These are independent. You can also install other appliances. There is no shared resources between rooms. They are independent.

Virtual machine : Like a building, the wall of the apartment in the building is pierced, which is a huge space. As much space as you need, you can use the isolation board to isolate the space. It is completely independent inside the space and has no impact outside the space. If you suddenly feel that the space is insufficient, you can also move the isolation board to expand the space, It has good scalability.

In addition, at present Amazon EC2 It supports free trial, and can be used for 12 months at most. If you need it, you can apply.
