However, since it lacks official support, users requiring technical assistance may need to seek external resources.
Package Management System
- Ubuntu: APT and DEB Packages
As a Debian-based distribution, Ubuntu uses the APT (Advanced Package Tool) for package management, utilizing DEB packages. APT offers extensive repositories, making software installation and management straightforward. Users can also leverage PPAs (Personal Package Archives) to access the latest software versions and custom applications. - CentOS: YUM or DNF with RPM Packages
CentOS, following RHEL’s tradition, uses YUM (Yellowdog Updater, Modified) or its successor DNF for package management, with RPM packages. RPM prioritizes stability, making it widely used in enterprise environments. It also provides numerous applications and middleware tailored for business operations.
Release Cycle and Support Period
- Ubuntu: 6-Month Release Cycle and 5-Year LTS Support
Ubuntu follows a semi-annual release cycle, ensuring users always have access to the latest features and performance improvements. LTS versions guarantee five years of support, making them ideal for those who value a stable environment. - CentOS: Long-Term Stability Aligned with RHEL
CentOS follows RHEL’s release cycle, with major updates occurring every few years. This makes it a reliable choice for businesses that require long-term stability. Some CentOS releases have support periods extending up to 10 years, making it ideal for critical systems.
Default File System
- Ubuntu: ext4 (ZFS Also Supported)
Ubuntu uses ext4 as its default file system, but it also supports ZFS, which is known for its advanced data integrity and protection features. This makes it ideal for handling large volumes of data and server operations. - CentOS: XFS and ext4
CentOS primarily uses XFS as its default file system, which is optimized for large-scale data operations. XFS offers excellent performance and scalability, making it a preferred choice for enterprise systems. ext4 is also available for those who need a more traditional file system.
User Interface
- Ubuntu: Desktop (GUI) and Server (CLI) Versions
Ubuntu offers both desktop and server editions. The desktop version includes a GNOME-based GUI, making it accessible for users transitioning from Windows or macOS. The server edition defaults to a CLI environment but allows GUI installation if needed. - CentOS: Primarily Server-Oriented with Optional GUI
CentOS is primarily designed for server environments and does not include a GUI by default. While a GUI can be installed, it is mainly intended for experienced users who prefer command-line operations. By not including a GUI, CentOS reduces resource consumption and maximizes efficiency for server applications.
4. Choosing the Right Distribution Based on Use Cases
