Ubuntu Server is the most widely deployed Linux distribution for dedicated server hosting, and for good reason. It combines a familiar package ecosystem, strong community support, long-term release cycles designed for production stability, and a security model that suits the demands of internet-facing infrastructure. For most teams deploying a dedicated server for the first time, Ubuntu Server is the default starting point and, in many cases, the right long-term choice.
However, Ubuntu Server is not the only Linux distribution available for dedicated hosting, and it is not always the best fit for every workload. Debian, AlmaLinux, Rocky Linux, and other distributions each have specific strengths that make them preferable in particular contexts. Understanding the differences between these options clarifies which distribution suits your workload, your team’s experience, and your operational requirements.
This guide explains what Ubuntu Server is, how it compares to the main alternatives, and how to choose the right Linux distribution for your dedicated server.

Before choosing a Linux distribution, it helps to understand what a dedicated server is and how it differs from shared and virtualised environments. Read What Is a Dedicated Server?, a complete introduction to bare-metal infrastructure.
What Ubuntu Server Is
Ubuntu Server is a Linux distribution developed and maintained by Canonical, a UK-based company founded in 2004. Unlike Ubuntu Desktop, which ships with a graphical interface and consumer applications, Ubuntu Server installs a minimal command-line environment designed specifically for server workloads. No desktop environment, no graphical applications, no unnecessary services running by default.
Ubuntu Server uses the APT package management system and the Debian package format, giving it access to one of the largest software repositories in the Linux ecosystem. Almost any server software available for Linux is available as a package or has documented installation instructions for Ubuntu Server.
Canonical releases Ubuntu Server on two tracks: standard releases every six months with nine months of support, and Long Term Support (LTS) releases every two years with five years of standard support and up to ten years of extended security maintenance. For dedicated server deployments, LTS releases are the appropriate choice, they provide a stable platform that does not require major upgrades every nine months and receives security patches for the full support period.
The current LTS release at the time of writing is Ubuntu Server 24.04 LTS, codenamed Noble Numbat, with standard support through April 2029 and extended security maintenance through April 2034.
Why Ubuntu Server Is the Most Popular Choice for Dedicated Hosting
Familiar Package Ecosystem
Ubuntu Server’s APT package manager and Debian-based package format are familiar to the largest pool of Linux administrators. Most web hosting tutorials, server configuration guides, and application deployment documentation assumes either Ubuntu or Debian as the target operating system. For teams deploying a dedicated server without a dedicated systems administrator, this documentation advantage is significant, the answer to almost any Ubuntu Server configuration question is available through a straightforward web search.
Strong Long-Term Support
Ubuntu LTS releases provide five years of standard security updates and up to ten years of extended security maintenance through Canonical’s Ubuntu Pro programme. For a production server that may run for several years without a major OS upgrade, this support lifecycle provides confidence that security patches will continue to arrive without requiring a disruptive distribution upgrade.
Active Security Updates
Canonical maintains a dedicated security team that responds quickly to upstream vulnerability disclosures. Security patches for the Ubuntu Server package ecosystem typically arrive within hours to days of upstream disclosure, faster than many alternative distributions for the most critical vulnerabilities.
Broad Software Compatibility
Most commercial and open-source server software officially supports Ubuntu Server as a deployment target. In particular, database engines, web servers, application runtimes, monitoring tools, and infrastructure software all provide tested packages and official documentation for Ubuntu. As a result, teams deploying standard web application stacks benefit from reduced risk of encountering undocumented configuration differences.
Cloud and Container Ecosystem Integration
Ubuntu Server is the default operating system for many cloud providers’ virtual machine images and is the most common base image for Docker containers. For teams managing infrastructure that spans dedicated servers and cloud or container environments, Ubuntu’s prevalence across all these contexts simplifies operational consistency, the same package management commands, the same configuration patterns, and the same administrative procedures work across environments.
Ubuntu Server vs the Main Alternatives
Ubuntu Server vs Debian
Debian is Ubuntu’s parent distribution – Canonical built Ubuntu on top of Debian’s package ecosystem, and the two distributions share the APT package manager and most of their package formats. Understanding the relationship between Ubuntu and Debian clarifies when to choose each.
Release stability – Debian Stable releases are more conservative than Ubuntu LTS releases. Debian packages are tested extensively before inclusion in Stable, resulting in older but more thoroughly vetted package versions. For workloads where maximum stability and minimal unexpected behaviour matter more than access to recent software versions: database servers, long-running infrastructure services, Debian Stable’s conservatism is an advantage.
Support lifecycle – Debian Stable typically receives about three years of full support plus two years of long-term support through the Debian LTS project. Ubuntu LTS provides five years of standard support, making it a longer-supported platform for teams that prefer infrequent major upgrades.
Community and documentation – both distributions have large, mature communities. Ubuntu’s documentation tends to be more beginner-accessible; Debian’s documentation is often more technically comprehensive. For experienced administrators, Debian’s documentation quality is excellent; for teams without deep Linux experience, Ubuntu’s more accessible resources are an advantage.
Practical difference – for most web application deployments, Ubuntu Server and Debian are functionally interchangeable. Teams with a preference for either will find their choice well-supported. Teams without a preference should default to Ubuntu Server for its longer LTS support lifecycle and broader beginner-accessible documentation.
Ubuntu Server vs AlmaLinux and Rocky Linux
AlmaLinux and Rocky Linux are both binary-compatible rebuilds of Red Hat Enterprise Linux (RHEL), created after Red Hat’s decision to discontinue CentOS Linux as a freely available RHEL rebuild. Both use the RPM package format and the DNF package manager rather than Ubuntu’s APT, a meaningful operational difference for teams accustomed to one ecosystem or the other.
Enterprise Linux compatibility – AlmaLinux and Rocky Linux are binary-compatible with RHEL, meaning software certified for RHEL runs on these distributions without modification. For organisations deploying software with enterprise support contracts that require RHEL certification, AlmaLinux or Rocky Linux provide the compatibility without the RHEL subscription cost.
Package ecosystem – the RPM/DNF ecosystem is mature but smaller than Ubuntu’s APT-based ecosystem. Some software packages are available for Ubuntu but not for RHEL-compatible distributions, or require additional configuration on RPM-based systems. For standard LAMP/LEMP stacks and common server software, both ecosystems are well-covered.
Security model – RHEL-compatible distributions use SELinux as their mandatory access control framework, compared to Ubuntu’s AppArmor. Both provide strong mandatory access control, but they require different configuration expertise. Teams familiar with SELinux will find AlmaLinux and Rocky Linux comfortable; teams without SELinux experience may find Ubuntu’s AppArmor easier to configure initially.
When to choose AlmaLinux or Rocky Linux – if the workload requires RHEL-certified software, if the team has deep experience with RHEL/CentOS administration, or if the organisation’s compliance requirements specify RHEL-compatible infrastructure, AlmaLinux or Rocky Linux are the appropriate choices. For teams without these specific requirements, Ubuntu Server’s larger beginner-accessible community and longer LTS support lifecycle make it the more practical default.
Ubuntu Server vs CentOS (and Why CentOS 7 Is End of Life)
CentOS Linux was historically the most common free RHEL-compatible distribution, widely used for dedicated server hosting through the 2000s and 2010s. Red Hat’s decision to shift CentOS to a rolling-release model (CentOS Stream) rather than a stable RHEL rebuild has made CentOS Linux effectively end-of-life for production use.
CentOS 7 reached end-of-life in June 2024, it no longer receives security updates. Running CentOS 7 on a production server exposes it to known, unpatched vulnerabilities. Any server currently running CentOS 7 requires migration to a supported distribution as an immediate priority.
CentOS Stream is a rolling release that sits upstream of RHEL, it receives updates before RHEL, which makes it less stable for production use than either RHEL or its binary-compatible rebuilds. For teams previously using CentOS Linux, AlmaLinux or Rocky Linux are the natural migration targets for workloads requiring RHEL compatibility; Ubuntu Server is the natural migration target for teams without a specific RHEL compatibility requirement.

Choosing the right Linux distribution is the first step, hardening it after provisioning is the second. Read Dedicated Server Security Checklist: How to Harden Your Server After Setup, a complete post-provisioning security configuration guide for Linux dedicated servers.
Choosing a Linux Distribution for Your Dedicated Server
Choose Ubuntu Server if:
Your team does not have strong existing familiarity with a specific Linux distribution, and you want access to the largest pool of beginner-accessible documentation and community support. Ubuntu Server is the right default for most new dedicated server deployments, its LTS releases are stable, well-supported, and compatible with the broadest range of server software.
Ubuntu Server also suits teams deploying standard web application stacks: LAMP (Linux, Apache, MySQL, PHP), LEMP (Linux, Nginx, MySQL, PHP), Node.js applications, Python web frameworks, and Ruby on Rails, where Ubuntu’s documentation coverage is comprehensive and most deployment guides assume Ubuntu as the target.
Choose Debian if:
Your team values maximum package stability over access to recent software versions, or has specific experience with Debian administration. Debian Stable is the right choice for long-running infrastructure services where tested, conservative package versions are preferable to more recent but less thoroughly vetted releases.
Choose AlmaLinux or Rocky Linux if:
Your workload requires RHEL-certified software, your team has established experience with RHEL/CentOS administration, or your compliance requirements specify RHEL-compatible infrastructure. Both distributions provide RHEL binary compatibility without the RHEL subscription cost, with active community support and regular security updates.
Avoid CentOS 7:
CentOS 7 is end-of-life and no longer receives security updates. So, migrate any CentOS 7 servers to a supported distribution immediately.

Is Ubuntu Server good for dedicated hosting?
Yes, Ubuntu Server is the most widely deployed Linux distribution for dedicated hosting. Its Long Term Support releases provide five years of standard security updates, its package ecosystem is the largest in the Linux server space, and its documentation is the most accessible for teams without deep Linux administration experience.
Ubuntu Server suits standard web application stacks particularly well: LAMP, LEMP, Node.js, Python, and Ruby on Rails all have comprehensive Ubuntu deployment documentation. Specialised workloads requiring RHEL-certified software, or teams with established RHEL/CentOS experience, may find AlmaLinux or Rocky Linux more appropriate. For most new dedicated server deployments without specific distribution requirements, however, Ubuntu Server is the right default. Read more about dedicated server setup in Dedicated Server Security Checklist: How to Harden Your Server After Setup.
What is the difference between Ubuntu Server and Ubuntu Desktop?
Ubuntu Server and Ubuntu Desktop use the same base package repositories and kernel, but differ significantly in what they install by default. The Desktop variant installs a graphical environment (GNOME), consumer applications, and services appropriate for a personal computer. Ubuntu Server, by contrast, installs a minimal command-line environment with no graphical interface and only the services necessary for network operation.
For dedicated server hosting, Ubuntu Server is the correct choice. The absence of a graphical environment reduces the attack surface, fewer installed packages means fewer potential vulnerabilities, and conserves CPU, RAM, and storage for the application workload rather than desktop services. A dedicated server managed entirely through SSH does not need a graphical interface, and adding one introduces unnecessary complexity and resource consumption. Read more about reducing the server attack surface in What Is Server Hardening? A Complete Guide.
Should I use Ubuntu LTS or a standard Ubuntu release for a dedicated server?
Always use an LTS release for production dedicated servers. Standard Ubuntu releases receive only nine months of security updates before reaching end-of-life, meaning you would need to perform a major OS upgrade every nine months to remain on a supported platform. For a production server, this upgrade frequency introduces significant operational overhead and risk.
Ubuntu LTS releases receive five years of standard security updates and up to ten years of extended security maintenance, meaning a server provisioned with Ubuntu 24.04 LTS in 2024 remains on a fully supported platform until at least 2029 without requiring a major upgrade. For dedicated server hosting, the stability and predictability of LTS support lifecycle is essential, it allows the team to focus on the application rather than managing frequent OS transitions. Read more about keeping your server secure and up to date in Dedicated Server Security Checklist: How to Harden Your Server After Setup.
Is Ubuntu Server more secure than other Linux distributions?
No Linux distribution is inherently more secure than another at the base level, security depends primarily on how well the server is configured and maintained, not on which distribution runs underneath. Ubuntu Server, Debian, AlmaLinux, and Rocky Linux all provide strong security foundations that a properly hardened server can build on.
Where distributions differ is in their default security tools and patching speed. Ubuntu uses AppArmor for mandatory access control; RHEL-compatible distributions use SELinux. Both provide strong protection when correctly configured. Canonical’s security team responds quickly to upstream vulnerability disclosures, typically delivering patches within hours to days of public disclosure. The most important security factor is not which distribution you choose but how quickly you apply security updates after they are released. Read more about server security in What Is Server Hardening? A Complete Guide.
What happened to CentOS and should I still use it?
CentOS Linux, the free, stable RHEL-compatible distribution widely used for server hosting — effectively ended when Red Hat shifted it to a rolling-release model called CentOS Stream. CentOS 7, the last stable release, reached end-of-life in June 2024 and no longer receives security updates. Running CentOS 7 on a production server is a security risk that requires immediate remediation.
CentOS Stream is not a suitable replacement for production servers, it sits upstream of RHEL, receiving updates before they are fully tested for stability. Teams migrating from CentOS Linux should consider AlmaLinux or Rocky Linux for workloads requiring RHEL compatibility. Without specific RHEL compatibility requirements, Ubuntu Server is the natural migration target. Read more about server migration in Dedicated Server Migration Checklist: How to Move Without Downtime.
How do I choose between Ubuntu Server and Debian for a dedicated server?
Ubuntu Server and Debian are closely related, Ubuntu is built on Debian’s package ecosystem, and for most web application workloads, both are equally suitable. The practical differences come down to support lifecycle, package recency, and documentation accessibility. Ubuntu LTS provides five years of standard support; Debian Stable provides approximately three years of full support plus two years of LTS. Ubuntu packages tend to be more recent; Debian Stable packages are more conservative and thoroughly tested.
For teams without a strong existing preference, Ubuntu Server is the more practical default, its longer LTS support lifecycle reduces the frequency of major upgrades, and its documentation is more accessible for teams without deep Linux administration experience. Debian is the right choice for teams that value maximum package stability, have established Debian administration experience, or prefer Debian’s more conservative release philosophy. Either choice is well-supported on Swify dedicated servers. Read more about dedicated server infrastructure in What Is a Dedicated Server?
