In a pecan shell, VPS (Virtual Private Server) Hosting is a type of server
hosting that enables websites and dedicated online applications to be hosted on the same physical machine. However, it allows the services to be completely independent – as if each were on its own separate machine.
Say what? How does VPS work, you ask?
A simple way to visualize how VPS works, is to use the “house analogy”.
Each virtual server or “container” on the machine is like a house. You can install any software you like (Windows, Redhat, CentOS, Ubuntu etc.) or restart your own container without affecting the other containers on the machine. Much like you can renovate each room of a house and equip it with furniture, paintings, curtains etc.
On a shared hosting server, problems on one of the websites might cause the entire server to crash – resulting in all of the other websites on that same server to go down with it. If for instance, the server encounters a problem, all websites will be affected.
However, on a VPS, only the problematic container would go down and the others would remain unaffected – offering you far more security than a shared server.
Still, why use VPS hosting?
This type of hosting will give you the independence and flexibility of dedicated hosting, but at the reasonable price of a high-end shared hosting service. This is ideal for people who have outgrown their shared hosting service, but don’t exactly have the need for a dedicated server.
- You have all the resources of a dedicated server at your disposal.
- This allows you to get more functionality out of your hosting environment, as it enables you to create small
business servers, hosting servers or any other kind of dedicated application that needs its own space.
- It is easily scalable – this means that you can start out small with very few resources – such as CPU, RAM or disk space and upgrade this within minutes with minimal downtime.
- It has astounding off-site back up capabilities and offers you full control.
- You are able to customize this machine completely to your own requirements and only pay for your preferred software.
- It uses far less resources than a dedicated server and is also considerably more energy efficient.
- It could be quite intimidating for a hosting novice.
- This may be research intensive if you are new to the concept.
- When compared to shared hosting that generally provides you with a control panel, you might have to manually install all requirements/dependencies and software.
The bottom line:
You do away with the old-fashioned method of installing large amounts of power-hungry, dedicated machines. Instead you create an energy-efficient virtual environment that can host multiple servers. These virtual private servers are hosted both in public & private “clouds” and have certainly revolutionized server hosting today.
