Virtual Private Server (VPS) hosting is where multiple websites use the same server, but have their own set resource limits on things like RAM and bandwidth. It also uses what’s known as a hypervisor (specialist software) to borrow resources from the other sites on the server if you’re maxed out and others aren’t using their full allocation.
WHAT IS THE DIFFERENCE BETWEEN VPS AND DEDICATED HOSTING?
Generally, VPS hosting is suited to small business websites, or large personal sites that need decent resource limits. No one wants the pain of slow loading speeds on their site, or worse still, to have their site constantly crashing. That’s why VPS hosting works well – it’s flexible in handling surges of traffic, and isn’t too expensive.
Virtual private servers are actually the most popular type of servers. This is because the performance of a VPS is much greater than Shared Hosting and even though there is a price break, you get what you’re paying for.
With VPS hosting, users may share a number of physical resources such as disk space, CPU and RAM, but still get to enjoy the freedoms of having a private server and your own control panel.
A virtual private server still allows users to be in charge, fully, of all their own settings and configurations. This allows you to customize and make any changes or adjustments that you need, as situations arise.
VPS users still have access to the same resources and features as they would have otherwise, and they still have the freedom to install any application and make changes to those applications. Since you are not actually sharing any hardware, you will not have to be concerned about the physical server maintenance and security
Dedicated hosting is the big cheese of the web hosting space. You don’t simply get a slice of stilton or a chunk of cheddar – you get the whole wheel of wensleydale. In essence, you have an entire server to yourself.
With a VPS the resources of the server will be split between different websites or hosting accounts. Think of it as a home computer that has many different users, all of who use the machine in different ways.
Virtual Private Servers have both high end and low-end options available. However, the cost usually ranges from $20/month all the way up to $100+/month. VPS servers usually have one or two hosting environments you can choose from, so they lack the absolute customization of dedicated hosts. But this does mean easier setup for those who have more basic websites.
This style of hosting will be enough for sites that are simpler and don’t receive massive amounts of traffic. Overall, you can think of VPS hosting as a perfect solution for those who require root access on a server, but don’t want the expense of a full dedicated server.
In addition to potentially getting, you more resources, the big advantage of this approach is that you have full control over the actual physical hardware inside your server and the software that’s running on it.
For example, maybe you prefer AMD processors to Intel processors – you have that level of control with a dedicated server. You can also control every single piece of software on that physical hardware.
Let’s go back to the housing analogy. In this scenario, a dedicated server would be like buying your own house. You’re the only person who owns that building – it’s 100% yours. What’s more, you have full authority to customize the entire building as much as you want.
A managed VPS or dedicated server is the opposite. With this setup, you’re still getting the dedicated resources for your site(s) as we discussed above. However, your hosting provider will still handle configuring, managing, and maintaining the server for you.
Like virtual reality, Virtual Private Server (VPS) hosting feels almost like having your own little world. VPS is similar to shared hosting in that multiple websites share the resources present on a single physical server. However, the difference between dedicated and VPS hosting are the restrictions placed on who can use the resources.
The web host uses a hypervisor, or software designed to create individual virtual machines on the server. This strict separation protects you from your neighbors, though all of you are still accessing a “shared” pool of resources (remember, though, that the server is likely to be more powerful and less “populated” than one used for shared hosting).
Furthermore, the resource allocation is divided evenly, and one website cannot take advantage of another’s resources (and vice versa). Think of it like owning a condo. Everyone can decorate their home to their own satisfaction — but they can’t knock down walls and take over their neighbor’s living room.
Shared Hosting is very similar to living in an Apartment Complex. All residents are in the same location and must share the available resources with everyone including the pool, parking lot, and playground. In shared hosting, all accounts must share the available resources with all the other accounts on the server. These include CPU time, memory, and disk space. Our System Administrators monitor all of our shared servers 24/7.
VPS Hosting includes our 4GB, 6GB, and 8GB plans and is similar to owning a Condo. While you still share things on the property, you are ultimately responsible for maintaining your own property and repairs inside the condo.
On a Virtual Private Server, not all resources are shared. The overall CPU time and memory are shared across all accounts on the machine, but at the same time, portions of those resources are always dedicated to each account.
When you use your computer, you're using an operating system. For most people, it's either Windows or the Apple OS. An operating system allows you to access the files on your computer, and it runs programs as well. Hosting providers do basically the same thing, allowing visitors to your website to access files on your site and enable processes, such as scripts.
Just like with a regular computer, the amount of RAM, storage and bandwidth will determine how fast or slow access is. Once you reach your storage, bandwidth or RAM cap, your website is liable to encounter problems or run slowly in the same way you'll run into problems if you try to do too many things at once on your computer.
The difference between different types of hosting comes down to how resources are allocated and who has control over them. Now that we've covered the basics of hosting, we'll start discussing the differences between VPS and Dedicated Hosting.
A VPS hosts the information of many clients on a single physical machine. But unlike shared hosting, it uses a hypervisor to separate tenants.
The VPS is known as a Virtual Private Server as all clients on the server appear as if they were on a separate dedicated machine. The VPS simulates this environment, cutting down on resources and cost.
Virtual private servers differ from shared servers through software and their availability of resources. However, the structure of both is physically similar.
VPS hosting is considered superior in that it offers significantly more resources (memory, computing power, running CPU, or graphics-intensive software or modules) than shared server hosting. A VPS server also provides a guarantee for resources that a client may use, while shared hosting does not.
The VPS is known as a Virtual Private Server as all clients on the server appear as if they were on a separate dedicated machine.

Performance matters. If you want to keep your clients happy, you need to provide them with top-notch performance. A survey conducted by Kissmetrics discovered that nearly half of web users expect a site to load in two seconds or less, and they tend to abandon a site that isn’t loaded within three seconds.
Furthermore, 79% of web shoppers who have trouble with website performance say they won’t return to the site to buy again and around 44% of them would tell a friend if they had a poor experience shopping online. The bottom line here?
Literally, a second difference in page load speeds has the potential to lose out on revenue from frustrated visitors.
MANAGED VPS HOSTING, SSD ‘S INCLUDED WITH EVERY PLAN
There comes a time in every successful business when you have to upgrade your resources, and hosting seems to be one of the first ones.
As your business becomes more and more popular among people, there comes a serious need to upgrade your hosting servers from “Shared” to VPS to handle the number of users coming in.
I am sure you know what over-utilizing server resources do to your business. If not, then you’re better off not knowing because that thing is frustrating.
A shift from “Shared” to VPS is often the best choice because it sits right between “Shared” and “Cloud.” While “Shared” is not enough, “Cloud” might not be necessary as of now, given that you’ve been using “Shared” all this time.
That being said, VPS hosting is definitely the best option when you’re just getting out of “Shared” hosting.
Random Access Memory or RAM is the component of your server that holds temporary data needed to complete the execution processes of the server. You need more RAM when the server has to complete multiple processes at the same time. Examples of cases where higher levels of RAM can generate significant benefits (in such forms as faster loading times and transaction processing)

HOW TO MAKE A VPS OUT OF A DEDICATED SERVER?
It is possible to create virtual private servers (VPS) out of a dedicated server. A physical server is split into smaller servers using the virtualization technology each of which run on individual operating systems and have dedicated resources like RAM, storage, CPU, network etc. This requires a technology called hypervisor.
One major function of the hypervisors is to isolate the operating systems and other applications from the underlying hardware. It is also referred as a virtual machine monitor(VMM). The primary server on which it runs is called as host machine and the virtual servers are called guest machines.
The first factor that you need to consider is how many VPS servers do you want. You must check the dedicated server configuration and specifications if it has the required capacity to handle the needs of the virtual machines that you create. Typically, you can create one or more as you require. If it is overloaded the performance may be affected.
The most significant requirement of setting VPS on dedicated server is use of hypervisor, which is an operating system designed to manage virtual servers with help of exclusive hardware. In practice, we can setup number of VPS on a single dedicated server. In order to partition a physical server into VPS, you need to make sure that the physical server is capable enough to accommodate needs of hypervisor.
In the next step you have to save configuration of the applications and data that may be currently running on the physical server. The hypervisor can be easily installed by simply inserting the disk into the reader. This should follow booting of hypervisor console, By referring to the manual for creating a Virtual Machine (VM) the virtual instance can be developed.
In the subsequent step you will be able to customize RAM, storage, CPU power, and memory as per your requirements. Now you are ready to install a Linux or Windows operating system in line with client's requirements.
The first and foremost thing you will need to consider a server before the setup , that you need to figure out as to how many VPS’s will you setup on a dedicated server along with calculation of your dedicated server profit. You can check the Dedicated server specifications and prices from the following link:-
Dedicated Server Node Configurations
Following is the calculation:
- If your dedicated server node costs: £200/Month
- You can create 20 VPS’s on dedicated server and price each VPS at £30.00/Month. So that means 20 VPS’s x £30/Month = £600.00/Month
You need a dedicated server with a Hypervisor in order to be able to manage VPS servers. (Server hardware requires the support of hardware-assisted virtualization (Intel VT or AMD-V))
Different ways for managing Virtual Server platforms,
using command line (Xen, KVM, openvz, etc)
using the integrated tools (Microsoft HyperV, VMWare, etc)
using open source/free virtual infrastructure control panel tools. example: Open-source virtualization and container platform Proxmox VE
