Choosing an operating system for your VPS matters-it affects what software you can run, how you manage the server, and how long you'll receive security updates. Here's a practical breakdown of the most popular options available at UnderHost.
AlmaLinux & Rocky Linux
AlmaLinux and Rocky Linux are enterprise-grade RHEL-compatible distributions. They replaced CentOS after Red Hat changed CentOS's release model in 2020, and both are now the standard choice for production web servers that need cPanel.
AlmaLinux 8 or 9 is the recommended OS if you're installing cPanel/WHM. It's the most tested and supported RHEL-compatible option on cPanel's official compatibility matrix.
- Best for: cPanel/WHM, DirectAdmin, production web servers, PHP applications
- Support cycle: AlmaLinux 9 through 2032; Rocky 9 through 2032
- Package manager: DNF (yum-compatible)
- Skill level: Beginner–Intermediate
Ubuntu
Ubuntu is the most popular Linux distribution for development and modern server stacks (LAMP, LEMP, Docker, Node.js, Python). It has the largest community, extensive documentation, and straightforward package management.
- Best for: Modern app stacks, Docker containers, aaPanel, development servers, beginners to Linux
- Support cycle: Ubuntu 24.04 LTS through 2029 (standard), 2034 (extended)
- Package manager: APT
- Skill level: Beginner–Advanced
Always choose an LTS (Long Term Support) version of Ubuntu for a server-currently 22.04 or 24.04. Non-LTS versions only receive 9 months of updates and aren't suitable for production use.
Debian
Debian is the upstream parent of Ubuntu and is valued for its extreme stability and conservative package approach. It runs well on minimal hardware and is widely used for servers that must be "boring" in a good way-no surprises, no unexpected changes.
- Best for: Minimal servers, high stability requirements, experienced administrators
- Support cycle: Debian 12 (Bookworm) through ~2026 (standard), ~2028 (LTS)
- Package manager: APT
- Skill level: Intermediate–Advanced
Windows Server
Windows Server is the right choice when your application specifically requires it-ASP.NET applications, Microsoft SQL Server, Active Directory, or Windows-only software. It's managed via Remote Desktop (RDP) rather than SSH.
- Best for: ASP.NET, MSSQL, .NET Framework applications, Windows-specific software
- Available versions: Windows Server 2012, 2016, 2022
- Management: RDP (Remote Desktop Protocol), PowerShell
- Skill level: Windows Server experience required
- Licensing: License cost is included in Windows VPS plans
Windows VPS plans cost more (license included) and use more resources. If you're running PHP, WordPress, or a standard web stack, a Linux OS is more efficient, better supported, and significantly cheaper.
