¶ The downsides...
Complexity: Running a server requires a certain level of technical expertise, and Ubuntu Server can be complex to set up and manage, especially for users who are new to server administration.
Limited Graphical User Interface: Ubuntu Server doesn't have a graphical user interface by default, so users have to manage it through the command line, which can be challenging for some.
No Pre-Installed Software: Unlike the desktop version, Ubuntu Server doesn't come with pre-installed software, which means users have to install the applications and tools they need themselves.
Resource Requirements: Running a server can require significant hardware resources, such as memory, storage, and processing power, so users need to make sure their hardware meets the requirements of the services they plan to run.
Maintenance Overhead: Ubuntu Server requires regular updates and maintenance to keep it running smoothly, and users must be proactive about managing security vulnerabilities and other potential risks.
¶ Ubuntu Server vs Ubuntu Desktop:
User interface: Ubuntu Desktop has a graphical user interface (GUI) with icons, windows, and menus, while Ubuntu Server has no GUI, and is designed to be managed remotely through the command line or terminal.
Software and packages: Ubuntu Desktop comes pre-installed with software and packages optimized for desktop use, while Ubuntu Server comes pre-installed with software and packages optimized for server use, such as Apache, PostgreSQL, and other server management tools.
System requirements: Ubuntu Desktop requires a more powerful computer with a higher-end graphics card, while Ubuntu Server is designed to run on less powerful hardware and is optimized for performance and efficiency.
Purpose: Ubuntu Desktop is designed for use as a personal computer operating system, while Ubuntu Server is designed for use as a server for hosting web applications, databases, and other services.
Security: Ubuntu Server is designed with a focus on security and stability, and includes additional security features not present in the Desktop version, such as automatic security updates.
¶ Ubuntu Server architecture
The Ubuntu Server architecture is a 64-bit, multi-architecture operating system that supports x86-64, ARM64, and PowerPC architectures. The server edition of Ubuntu is designed for use in servers, mainframes, and other large, enterprise-level systems. It is optimized for running headless, with no graphical user interface, and focuses on stability, security, and scalability. The architecture is modular, allowing for easy customization and extension, and supports various server applications, including databases, web servers, cloud computing, and virtualization.
