What is VPS Server?
A Virtual Personal Server (VPS) is a virtualized server that resides on a dedicated server on a physical machine having multiple Operating Systems. In other words, you have a dedicated space within a shared hosting environment.
The physical server is placed at some location by hosting provider. A portion of this server is allotted to multiple different VPS servers, which consist of their own independent server resources like operating system, storage and memory. It behaves like a dedicated server but at a reduced cost and more customization options to the liking of the user.
VPS Servers are used for VPS hosting, which is one of many types of web hosting that you can select from to create a web presence on the Internet. Dedicated is memory is allotted to store the website files on the VPS server. There can be other websites with their own dedicated space but privacy is here maintained by no access to other website files.
In layman’s terms, it can be explained as an apartment in a building with its own unshared facilities. The Physical server is just like a building and the apartments are like VPS Servers (dedicated portion or area). Within an apartment, one who rents it is allowed to make customizations and repairs. He also enjoys the right of accessing the resources (kitchen, toilet, parking space etc.) which are specifically allotted to him.
How are VPS Servers different from Shared and Dedicated Servers?
With dedicated servers, you have access to an entire server. Dedicated servers have huge amounts of resources and can perform much better for high demanding application and websites. Therefore, it is an optimal choice for individuals and organizations that have high traffic to their websites, but the cost will be much higher than a VPS Server.
In shared hosting, you have access to a small portion of the server. Multiple websites are hosted on a single server and server resources and storage is shared among them. It is an economical choice for ones who are just getting started with their websites. Nevertheless, not an appropriate choice for those who have high traffic on their websites since servers can malfunction.
In contrast to shared and dedicated servers, the VPS servers offer you a dedicated amount of memory, which reduces the risk of server overburdening. Further, these are easy to maintain and less expensive than dedicated servers.
Working of VPS Servers
If you are aware of Virtual Box or VMware, you might know that these are the software applications, which you allow to run more than one Operating Systems on a single machine. These operating systems are, virtualized, having dedicated storage and RAM. The working of VPS Servers is same as that of Virtual Box or VMware. Several virtualized servers exist on a single server with dedicated storage and RAM.
Pros of VPS Servers
Privacy is less concerned in VPS servers since you are not sharing the server with anyone else. Hence, your website files stored on the server are highly secured.
Having a dedicated space allows you to have your own Operating System. You have your own instances of the software applications installed on this Operating System. You are able to customize and make changes in your dedicated portion of the server as per your requirements.
You have full control on your server without being dependent on anyone. Let us say you are installing some software applications and you need to restart your server. You are able to do this at any time. Although you are sharing your dedicated server with other VPS servers, your act of restarting the server will not affect the other servers.
Dedicated Memory and Resources
Not only you have dedicated storage in VPS servers but you also have a dedicated amount of RAM. As a result, even in a shared environment the speed and performance of your website will not be affected by the other websites.
Cons of VPS Servers
One of the drawbacks of purchasing a VPS Server is its cost. Although it is cheaper than a dedicated server is, but is relatively expensive compared to a shared webbhotell. In addition, it requires technical knowledge on your end for monitoring and maintaining the server. Moreover, if the physical server fails, all the VPS servers residing on it will be down. Scalability is another big concern in VPS Servers. If you are out of space on your VPS or you have a storage limit, you might have to buy more storage or switch. Just in case, if you have no option other than to migrate your website, it may take several hours or even up to many days.
In a Nut ShellWhen you have a high number of visitors frequently, visiting your website, then it might be the time that you can switch to VPS Servers for your website. People usually consider VPS servers to host their websites when they require more server control options and customization. In fact, people enjoy having more control over their hosting environment and one of the reasons why VPS Hosting has become popular in recent years.
