VPS hosting - what is it?
As the name suggests, Virtual Private Hosting is a type of hosting setup in which your website is run from a virtual machine. What does that mean? Well, at the end of the day, every web page and everything on the internet has a home on someone's hard drive at one place or the other.
However, the beauty of the best VPS web hosts is that you don't necessarily need to rent out new hard drive space or install additional computing power and resources from them for every website you want to launch. You can simply opt for a virtual server, in which your host will partition specific resources for you from a larger pool of computing resources that already exists.
There are numerous benefits to doing this. First of all, you have your own mini server on what might otherwise be a shared machine. This means that no one can use your bandwidth, memory, drive space, or other resources.
You also have more control over what is installed on your virtual machine, and this is great for flexibility and customization. Finally, there are significant cost savings with VPS solutions as compared to dedicated servers, even though across the majority of top VPS web hosts both are very similar in terms of performance and what your host gives you.
Who might need VPS hosting?

If you already have an up-and-running website on a shared plan and want to take things to a higher, more performant level that is more secure and more customizable, register with any of the companies recommended above.
They're guaranteed to be the best hosting plans for VPS. They help you avoid the downtime and slow website response time often seen with shared plans, which means you can better manage spikes in traffic (which also means this is a great option for people whose websites are gaining traction and are attracting more and more visitors).
Also, if you want to be able to install software of your own or play around with admin settings and tweak things to certain specifications, a VPS web hosting plan is the way to go, because you'll be able to do all of those things without compromising security or performance.
