Advantages and disadvantages of VPS
Benefits of VPS
- economy. VPS usually costs less, than physical servers, while providing similar opportunities.
- Independence. VPS is an isolated software platform, available only to you and your team. Even the host provider (eg, such as SITA) does not have access to your virtual server.
- Less equipment liability. You are not responsible for the physical condition of the equipment, which makes server management easier.
- Good technical equipment. VPS offers a wide range of technical capabilities, which can be customized to suit your needs.
Disadvantages of VPS

- Limited hardware control options. You may not change or improve the physical hardware, on which your VPS is running.
Two types of virtualization: OpenVZ and KVM
There are two main virtualization technologies, used to create VPS: OpenVZ and KVM. Let's look at their differences.
OpenVZ
- Dynamic resource allocation. The number of available resources varies depending on the load on your project.
- Configuration flexibility. You can change the characteristics of your virtual server without rebooting the operating system, but you need to pay for additional resources.
- Sharing resources. Since other users may be using the same host at the same time, performance may be reduced.
- Linux only. Only Linux-based operating systems can be installed on OpenVZ servers.
Pros and cons of OpenVZ
| pros | Minuses |
|---|---|
| Container based | Should work on Linux |
| Easy setup | Common core |
| Friendly for newcomers | Less privacy |
| Easily scalable | |
| Very affordable |
KVM
- Static resource allocation. The amount of hardware resources is fixed, which makes KVM more like a physical server.
- Changing configuration requires a reboot. To change CPU and RAM parameters, you need to reboot the server.
- Complete independence. No one, including host administrator, does not have access to your data.
- Support for various OS. You can install any operating systems, including Windows and macOS.
Pros and cons of KVM
| pros | Minuses |
|---|---|
| Full virtualization | More overhead |
| Any operating system | There is no possibility to reduce resources |
| Full control | |
| Complete privacy | |
| Affordable price |
