what is vps hosting 什么是vps

在使用vps主机之前我们需要知道 什么是VPS——what is vps hosting?以及为什么使用VPS。

英国UK有很多家vps hosting 供应商,那么什么是VPS呢？

VPS hosting is a type of web hosting that uses Virtual Private Servers. Although the websites are hosted on the same physical machine, VPS allows each website to be fully independent as if each were on its own separate machine.

How VPS works

The easiest way to visualize how VPS work is to use the apartment analogy. Each virtual server, or “container”, on the machine is like an apartment suite. You can install any software you like or restart your own container without affecting the other containers on the machine, much like how you can renovate your own suite without affecting the others.

On a shared hosting server, problems with one website might cause the entire server to go down, causing all of the other websites on that server to go down with it. This would not happen on a VPS machine because only the problematic container would go down, but the other containers would be unaffected.

Similarly, some high traffic websites in a shared hosting environment may hog all of the server’s resources, thus causing other websites on that server to be unreachable. This would not happen on a VPS machine as each container may only use the resources that are allocated to it.

Why use VPS Hosting?

VPS is great as it slips in nicely and bridges the gap between shared hosting and dedicated hosting services. VPS will give you the independence and flexibility of a dedicated hosting service, but at the price of a high-end shared hosting service.

For users whose websites have outgrown their shared hosting service but can’t quite afford a dedicated server, VPS hosting may be the best solution.

VPS主机是虚拟主机类型，使用虚拟专用服务器。虽然网站是托管在同一台物理机器，定位系统允许每个网站是完全独立的，如果每个其自己单独的机器上。
VPS如何工作？

直观地了解VPS的工作方式，最简单的方法是使用公寓的比喻。每个虚拟服务器，或“容器”的机器上，就像是一个公寓套房。你可以安装任何软件，你喜欢或重新启动自己的容器，在不影响其他机器上的容器，更喜欢在不影响他人的情况下，如何可以改造自己的套房。

共享托管服务器上，一个网站的问题可能会导致整个服务器下去，造成该服务器上其他网站去。一个VPS机器上，这不会发生，因为只有问题的集装箱会往下走，但其他容器将不受影响。

同样，在一个共享的主机环境中的一些高流量的网站可能会霸占所有的服务器的资源，从而导致无法访问该服务器上的其他网站。这不会发生在一个VPS机，每个容器只可使用分配给它的资源。
为什么使用VPS主机？

VPS是伟大的，因为它很好的和桥梁的共享主机和独立主机服务之间的差距滑倒。 VPS会给你一个专门的托管服务的独立性和灵活性，但在高端的共享主机服务的价格。

对于用户的网站已经超出了他们共同的托管服务，但不能完全负担得起一个专用的服务器，VPS主机可能是最好的解决办法。
