Virtual private server explained
What is VPS hosting?
A clear explanation of VPS hosting, how virtualization works and when to choose a VPS over shared hosting.
What is a VPS server in short?
A VPS (Virtual Private Server) is a virtual server with guaranteed CPU, RAM and disk resources, isolated from other users through KVM virtualization. It provides root access and full control over the operating system. You need one when you outgrow shared hosting — more than 50,000 visits per month, web applications with specific configurations, or a requirement for security isolation. BeoHosting VPS from €15/mo (2 CPU, 4 GB RAM, 80 GB NVMe).

What is a VPS and why does it matter?
A VPS (Virtual Private Server) is a virtual server that behaves like an independent, dedicated server, but physically resides on one larger server alongside other VPS instances. Each VPS has its own guaranteed resources — processor (CPU), memory (RAM) and disk space — which are completely isolated from the other VPSs on the same physical server.
Think of it this way: the physical server is like a large building, and each VPS is like an apartment in that building. Every apartment has its own walls, door and key — the residents are isolated from one another, have privacy and their own resources (electricity, water), but share the common infrastructure of the building (foundations, roof, network). In the same way, a VPS gives you the privacy and guaranteed resources of a dedicated server at a far lower price.
VPS hosting is ideal for users who have outgrown shared hosting but do not need a whole dedicated server. It strikes the perfect balance between performance, control, security and price. A VPS is the most common choice for growing business sites, web applications, e-commerce stores and sites with higher traffic.
How does virtualization work?
Virtualization is the technology that makes it possible to create multiple virtual servers on a single physical server. It uses software called a hypervisor (or Virtual Machine Monitor) to split the hardware resources of the physical server into isolated virtual machines.
There are two types of virtualization used for VPS hosting:
KVM (full virtualization)
KVM (Kernel-based Virtual Machine) provides full hardware virtualization where each VPS has its own operating-system kernel. This delivers maximum isolation and flexibility — you can install any OS and have complete control over the system.
- Full resource isolation
- Its own kernel
- Any OS
- Highest level of security
Container virtualization
Container virtualization (OpenVZ, LXC) uses a shared operating-system kernel for all VPS instances. It is less resource-intensive but provides weaker isolation. All VPS instances must use the same operating system (usually Linux).
- More efficient resource use
- Faster restart
- Lower price
- Linux OS only
BeoHosting uses KVM virtualization for all VPS plans, because it provides full resource isolation and the highest level of security and stability. Every VPS has its own kernel, guaranteed CPU cycles and RAM that are never shared with other VPS users on the same server.

When do you need VPS hosting?
Moving from shared hosting to a VPS is a natural step as your online project grows. But how do you know when the time is right? Here are clear signs that you need a VPS:
Your site is getting slower
If you notice the site loading more slowly than before, especially during higher-traffic periods, that is a sign you have outgrown shared hosting. On a VPS you have guaranteed resources that do not depend on other users.
You have more than 50,000 visits per month
Shared hosting can work for up to 30,000–50,000 visits per month (depending on the type of site). Above that, a VPS is recommended for stable performance and fast server response.
You need root access
If you need to install specific software, configure PHP/MySQL in a particular way or run custom processes, a VPS gives you full control with root access.
You run a web application
Node.js, Python/Django, Ruby on Rails or other web applications require a specific server configuration that shared hosting does not provide. A VPS lets you install and configure everything you need.
Security is critical
For e-commerce sites, medical data, financial applications or law firms, the full isolation of a VPS provides a higher level of security than shared hosting.
