How Does A Linux Virtual Server Work ? And How do you sign up for one?

Linux Virtual server’s are amazing for people who are looking for a way to have their websites hosted. For some, this can be a pretty tough task – a lot of people out there really don’t know where to start when it comes to picking the best method of hosting, let alone whether or not Linux virtual server will provide the most bang for their buck.

Often times, people just go with what they recognize, making the linux virtual server something that they should be thinking about. While it’s good, there are definitely as many if not more great things about the Linux VPS. Here, we’ll talk a little bit about that, as well as get into how it works.

The goal is to make people more informed, not necessarily rave on about how this virtual server is better than the competition. While we may feel a certain way, that’s not saying that this is necessarily the case for some. In fact, for some, we would definitely recommend the opposite of what we actually think is the better. Different strokes for different folks, as they say.

How it Works

Now, the Linux virtual server is implemented in three different ways. Linux has three IP load balancing techniques that exist together in the Linux Director. The three is the virtual server via NAT, Virtual Server via Direct Routing, and virtual server via IP tunneling.

All three of these things can potentially be pretty good for people who are looking for hosting, though they all have their advantages and disadvantages. As we explore the three different types, we’ll talk a bit about what these benefits and drawbacks are.


First, we think it would be a good idea to talk about the advantage of the virtual server with NAT. One of the biggest advantages is that the virtual server via NAT is that the real servers can run any operating system that supports the TCP/IP protocol. NAT also only need an IP address for the load balancer.

It can also use private Internet address, too. Of course, there are others, but some of those are for the whole shebang, not necessarily using it via NAT. Now that it’s out of the way, there are some disadvantages of the virtual server via NAT.

The biggest disadvantage is that the scalability of the virtual server is limited. Unfortunately, there is a chance that the load balancer may bottleneck the whole system when the number of nodes – which are general PC servers – increase to about 20 or more, because the response and request packets need to be rewritten by the load balancer.

Fortunately enough, the virtual server via NAT can meet the performance request of many servers. In the event of a bottleneck, there are some methods to solve it via the other two methods that we’re going to talk about.

Via IP Tunneling

When working with the Linux virtual server via NAT, the request and response packets need to pass through the load balancer. In the virtual server via IP tunneling, the load balancer works a bit differently, and in a good way – we think.

Instead of what the virtual server does via NAT, the balancer just schedules requests to the different real servers, and the real servers return replies to the users. This means that the load balancer is capable of handling a huge amount of requests. It also won’t bottleneck the system and has the ability to schedule over 100 real servers, too.

The IP tunneling feature can also be helpful in building a high-performance virtual server, which can access the Internet directly to get objects and bring them directly to the users.

Linux Virtual Server via Direct Routing

Here, much like in the virtual server via tunneling, LinuxDirector processes only the client-to-server half of a connection in the virtual server through direct routing. The response packets follow a separate network route to the clients.

This means that the server can scale a great deal. Also, when you think about this in context of the virtual server via IP, this approach won’t come with the tunnel overhead, but it will require one of the load balancer’s interfaces as well as the real server’s interfaces to be in the same segment for it to work.

Virtual servers can really be useful for people who are trying to host their websites, especially when you think about how much money you have the ability of saving. people like Linux because it’s not too hard to work with, and you get to save even more money because you’re not paying for the licensing that Windows servers will cost you.

This is great for people who are trying to run a business, and while it may require a bit more of a specialist’s hand, there are a ton of resources that may be beneficial to you if you don’t want to spend a lot of money on IT.

And even though you may not need to know exactly how it works, you now have the ability to understand it a good amount more of how it works. I hope you enjoyed this Tutorial and can now see how the linux server works. We have also recommended a company that offers the best linux virtual server, there support is amazing and we offer a coupon code as well.
