What is a Hypervisor For a Virtual Private Server?

When you first start trying to understand virtual private servers, you'll probably hear the term "hypervisor" a lot. But what is a hypervisor, and what does it have to do with your virtual private server?

To understand what a hypervisor is, you must first understand what a virtual private server is, and how they work. A virtual private server is one server that's split up into many different servers. Think of a VPS Australia as an apartment building. While there is only one building, it's separated into different units and people rent just one unit for their own use, without anyone unit really having an effect on another. This is the same way that a virtual private server works.

The hypervisor allows for true virtualization so that each owner of each virtual website can do whatever they'd like to their VPS in Australia. They can install their own operating system, and use their own drivers and software on their own VPS. Because a hypervisor allows for true virtualization, nothing on a virtual private server will rely on any underlying software.

So you've heard about the hypervisor on a virtual private server; but in fact, only VPSs that use hypervisor visualization will come with this type of technology. If you're looking at OS-level virtualization, you'll be receiving a much different Australian VPS, and you need to know what that difference is.

With OS-level virtualization, the VPS Hosting Australia will already have an operating system, a kernel, hardware, drivers, and more that will need to be used by every virtual server that's located on the virtual private server. You'll still have your own virtual server in the way that you'll be able to use as much bandwidth and storage space as you want, and you can reboot your own virtual server without having any effect on the other websites being run off the physical server. However, you won't be able to fully customize it as you would be able to with a virtual private server that works with a hypervisor.

Upgrading Your VPS Server

Often when you sign up with a shared web host or even a dedicated web host, there's no option to upgrade your servers. This is because with a shared host, you're sharing the resources within that server and so, there's no real opportunity for you to upgrade what you have. With a dedicated server, on the other hand, you're given the entire server – and all of its possible resources – at the time you sign up. But one of the biggest benefits that come with virtual private servers is that you can upgrade whenever you need to, and whenever you need more bandwidth, storage space, or any other resources.

A virtual private server is really a server within a server. Your website's data will be stored on the same server as many other websites, but there will be a virtual wall separating all of them. So another person's website will never interfere with your own. However, this doesn't mean that you'll be limited to the resources within your own virtual server; you can always upgrade so that you can use more. And this upgrading can happen in one of two ways.

The first way is very straightforward and will only require that you put in a call to your VPS host. Because VPS hosts usually don't sell every single bit of resources that are on their machines, this would just mean that the web host would need to allow you more resources. For this, there will usually be a charge, depending on the amount and the type of resources you need, but a long process of switching servers might not be necessary.

If you need a great deal more resources than what you currently have, or if you're changing your package completely, you may need to be moved to a different server. This will only be required if the resources that are left on the server aren't enough to suit what you're looking for. If this is the case, your VPS host will simply find you another one of their virtual private servers that has enough room on it to accommodate what you need.

If you need to be moved to a virtual private server, don't worry about a huge transfer process that will take a very long time. Moving data from one Australian VPS Hosting to another should take no longer than 30 – 60 minutes, during which time your site will unfortunately not be up and running. Because of this, make sure that you ask your host if it's possible to make the transfer during a non-peak time, such as in the middle of the night or very early in the morning. This will ensure that most visitors aren't even aware of the switch and that you don't lose too much business because of it.

Conclusion

Virtual private servers can be a great help to a great many companies. They are a wonderful bridge between shared and dedicated hosting, something that many businesses struggle with; and they are much more affordable than some options out there. However, so many business owners think that the term "virtual private servers" covers every type of VPS that is out there, and that's not the case. When you need true virtualization, and you do if you're choosing VPS, make sure that you're choosing Hypervisor-based VPS and not OS-level virtualization. It's the only real way to make sure that you're getting exactly what you thought you were.

One of the biggest benefits of using a web host that offers virtual private servers is that they are extremely flexible. And if you need to change or update your VPS, it's much easier than when you try with any other type of web hosting.
