The operating system is the base layer of a VPS: it decides which software you can install, how you manage the server and how long you get security updates. For almost every website, app or API in 2026, the right choice is a current long-term-support Linux release. This page is the short guide to choosing; our full article covers reinstalling and switching.
Choose Ubuntu 24.04 LTS for most web apps, Docker and Node.js, Debian stable for a lean server, or AlmaLinux or Rocky Linux if your software expects the Red Hat family. Avoid CentOS and any release whose standard support has ended. Domain India VPS plans are self-managed Linux servers; you can reinstall a different OS yourself from the Rebuild tab of your VPS page.
See Installing or reinstalling an operating system. It covers what a reinstall erases, how to back up first, how to reinstall from your VPS page, and how to secure the new server.
1. The main Linux choices
| Operating system | Family | Best for |
|---|---|---|
| Ubuntu 24.04 LTS | Debian | Web apps, Docker, Node.js and Python; the most widely documented choice |
| Debian (current stable) | Debian | Lean, stable servers that change rarely |
| AlmaLinux or Rocky Linux | Red Hat compatible | Software and panels built for the RHEL family |
All three are free and open source, have long security-support windows and run the common web stacks: Nginx or Apache, PHP, Node.js, Python, MySQL, MariaDB and PostgreSQL. For a deeper comparison of the families, see An overview of popular Linux distributions and Why AlmaLinux and Rocky Linux replaced CentOS.
CentOS 7 and 8 and Ubuntu 20.04 no longer get standard security updates. A new server should start on a release with years of support left, not one you will have to migrate away from soon.
2. How to choose
- Follow your software. If an application, control panel or vendor supports only certain distributions, pick one of those.
- Pick what you know. Commands differ between families:
apton Ubuntu and Debian,dnfon AlmaLinux and Rocky Linux. Choose the one you or your developer already use. - Check the support window. Prefer LTS releases, and note the end-of-support date when you install.
- Mind the resources. Linux without a desktop runs comfortably on a small VPS. Leave headroom for your database and application.
3. What about Windows?
Domain India VPS plans run Linux only: Ubuntu 24.04 and 22.04, Debian 12 and 13, AlmaLinux 9 and Rocky Linux 9. Windows is not offered on VPS. If you need to host ASP.NET websites or MSSQL databases, Windows shared hosting with Plesk is the route; see the Plesk Windows hosting guide.
4. Control panels on a VPS
A VPS can run with no panel, managed over SSH, or with a panel you install yourself on top of the OS. A VPS comes without a panel, and cPanel is not offered on Domain India VPS plans. If you plan to install a panel, choose an OS that the panel currently supports.
5. Domain India VPS
Our VPS plans run on KVM with full root access and NVMe storage. They are self-managed: you install, secure, update and back up your own software. To switch operating systems later, back up your data and reinstall from the Rebuild tab of your VPS page; the reinstall erases the whole disk and keeps your IP address.
- 1 vCPU
- 2 GB DDR4 RAM
- 64 GB NVMe SSD Storage
- 2 TB Monthly Bandwidth
The price on the card is a live Domain India list price and excludes 18% GST.
Which operating system is best for a VPS?
For most websites, apps and APIs, Ubuntu 24.04 LTS is the easiest choice because it is widely documented and well supported by Docker, Node.js and Python tools. Debian stable suits lean servers, and AlmaLinux or Rocky Linux suit software built for the Red Hat family.
Should I use CentOS on a new server?
No. CentOS 7 and 8 have reached end of life and no longer receive security updates. Use AlmaLinux or Rocky Linux if you need Red Hat compatibility.
Can I get Windows on a Domain India VPS?
No. Domain India VPS plans run Linux only. For ASP.NET websites, Windows shared hosting with Plesk is the simpler route.
Can I change my VPS operating system later?
Yes. Back up everything to storage outside the VPS, then reinstall from the Rebuild tab of your VPS page. The reinstall erases the entire disk; your IP address stays the same.
Is cPanel available on a Domain India VPS?
No. A VPS comes without a panel and you can install one yourself; cPanel is not offered. For cPanel, choose cPanel shared hosting instead.
