What Is A Virtual Private Server, And How Does It Work?
What is a VPS?
To understand a VPS, we need first to recognize the three facets of it; virtual, private, and server. A server is a storage hosting service that stores all the data of a website and gives functionality to it. It is usually a physical device rooted in a computer.
A VPS, with its virtualization technology, can make one server function as several virtual servers. That means you can get separate servers to manage different websites out of a single hardware. These virtual servers provide dedicated service to the websites. A user does not have to share any data with other users. Hence, it’s private.
In a nutshell, a VPS is a hosting service that offers private servers to clients from a shared environment. It is different from a shared hosting experience because it gives complete control of the virtual servers to the client. Furthermore, unlike shared hosting, it has separately allocated spaces and bandwidth to allow seamless functioning of multiple servers simultaneously.
A VPS is used for managing a comparatively smaller amount of traffic than a dedicated server. Although it has the same utility and almost equal security as a dedicated server, storage capacity and bandwidth are lesser. Therefore, it is generally used for websites that need stable performance to handle 1000 – 3000 real-time visitors. It is thus suitable for medium-sized eCommerce websites, email servers, virtual workstations, and data management systems.
Now, keeping all that in mind, let’s see how it works.

How does VPS work?
VPS gives you a dedicated server experience while you’re actually sharing a single physical server. This is primarily done through hypervisor software that runs on the physical server. The physical server that runs this hypervisor software is typically called a hypervisor. The hypervisor software manages the virtual servers, including storage allocation, virtual disk management, CPU resource allocation, etc. Using the virtualization technology, the software makes separate spaces for each VPS and helps communicate with the hardware. Furthermore, due to the virtual segmentation, each VPS can run on a different operating system.
To understand the applicability of a VPS, let’s look into the different hosting experiences it can offer. There are two basic types of VPS’s: a Managed VPS Host and an Unmanaged VPS Host. This division is primarily based on the amount of responsibility shared between the client and the service provider.

In a managed hosting experience, the service provider is responsible for managing all the necessary services, including virtual and physical server maintenance, installation and upgrading of applications, security monitoring, and technical support. Therefore, those who either do not have prior knowledge of server configuration or cannot afford to invest time and money to deal with the intricate details of server management prefer this type of hosting experience. Furthermore, it reduces the workload of the client, helping them focus on their business.
Managed VPS hosting ensures server consistency as it is the provider’s responsibility to ‘serve up’ the client website. It also provides enhanced usability as the service provider looks into the proper resource allocation so that a website functions flawlessly. Along with that, the provider is also responsible for handling security concerns.
On the other hand, unmanaged VPS hosting provides complete control of the server to the client. In this case, the host or the service provider is not responsible for the maintenance nor management of the server. The host is only bound to provide a functional VPS to the client. Those with proper knowledge of VPS configuration may consider choosing this type of service. Additionally, with unmanaged hosting, the client gets to customize the VPS to their preferences.
Unmanaged VPS hosting is also cheaper than managed hosting. Additionally, the client can enhance the security levels, website usability, installations, and upgrades as they wish. However, without the appropriate knowledge and expertise, managing a VPS can be challenging.
However, it’s important to note that for both managed and unmanaged hosting experience, the service provider is responsible for managing and configuring the hypervisor software.
VPS has become one of the most crucial factors in enhancing the azxs digital footprint of a business. As a result, several big players and numerous small-scale hosts are providing fairly competitive pricing for VPSs, in both managed and unmanaged forms. However, when choosing a VPS hosting package, it’s essential to consider a website’s requirements and assess the feasibility of server management before choosing between a managed and unmanaged host experience.
