Linux and AIX are widely used operating systems that cater to different needs and environments in computing globally. While Linux is an open-source running gadget extensively used in various computing platforms, including servers, desktops, and embedded structures, AIX is a Unix-primarily based running system advanced via IBM mostly for organization-stage servers and excessive-overall performance computing environments. In this article, we are going to discuss the differences between Linux and AIX but before that, you should understand what are Linux and AIX and their features, Let’s discuss them one by one:

What is the Linux Operating System?

Linux is a group of open-source Unix-like operating systems that was developed by Linus Torvalds. It is a package of Linux distribution. Some of the most used Linux distributions are Debian, Fedora, and Ubuntu. It was written in C language and assembly language. The kernel used in Linux is a Monolithic kernel. The target systems of Linux distributions are cloud computing, embedded systems, mobile devices, personal computers, servers, mainframe computers, and supercomputers. The first version of Linux was launched in 1991. The most recent version of Linux for personal computers is 5.6 (kernel).

Features of the Linux Operating System

  • Linux gives a command-line interface for superior customers and builders.
  • Linux has a huge repository of software applications, which can be easily mounted and managed the usage of package deal managers.
  • Linux is an open-supply working system, which means that its supply code is freely available to anyone and can be changed and redistributed.
  • Linux is highly customizable, and customers can modify and configure the system to suit their unique needs and options.
  • Linux supports a couple of desktop environments, which allows users to choose the interface that they prefer.

Advantages of Linux

  • Linux offers vast customization options, allowing users to tailor their systems consistent with their alternatives.
  • Linux systems are regarded for stability and robustness, often walking for prolonged intervals without crashing.
  • Linux is less at risk of malware and viruses as compared to other operating structures.
  • Linux is freely Available.
  • Linux has a substantial and energetic network that provides assist, documentation, and a extensive variety of software.

Disadvantages of Linux

  • Some proprietary software program and hardware drivers might not be with no trouble available or optimized for Linux.
  • While gaming on Linux has improved in current years, it nevertheless lags behind Windows in phrases of game availability and performance.
  • Linux could have a steep learning curve for customers acquainted with different running systems, particularly for tasks which includes system administration and troubleshooting.
  • The variety of Linux distributions and package management structures can result in fragmentation.

What is AIX Operating System?

AIX is a series of operating systems which is provided by IBM. AIX is a short form of Advanced Interactive eXecutive. Initially, it was designed for the IBM RT PC RISC workstation and later it was used for various hardware platforms like IBM RS/6000 series, PowerPC-based systems, System-370 mainframes, PS-2 personal computers and Apple Network Server. It is one of the five commercial operating systems that have versions certified to UNIX 03 standard of The Open Group. The first version of AIX was launched in 1986. The latest stable version of AIX is 7.2.

Features of AIX

  • Advanced Interactive eXecutive operating system is highly secure.
  • It fully supports all versions of Oracle.
  • The IBM AIX OS is a new version that enables users to apply new patches without restarting the system.
  • It is an extremely reliable and versatile operating system.
  • It offers higher efficiency.

Advantages of AIX

  • AIX is designed for business enterprise-stage environments, that provide high scalability
  • AIX is highly reliable
  • AIX offers powerful gear like System Management Interface Tool (SMIT) and AIX Logical Volume Manager (LVM) for simplified management responsibilities.
  • AIX is supported via IBM, offering comprehensive technical aid and organization-grade solutions.
  • AIX is optimized for IBM Power Systems servers, supplying advanced functions for overall performance tuning and optimization.

Disadvantages of AIX

  • AIX is a operating system owned via IBM, which may restrict customization options and dealer lock-in(vendors lock-in).
  • AIX is not cost effective
  • AIX management may have a learning curve for users unusual with Unix-based operating structures, requiring schooling and information.
  • AIX is optimized for IBM Power Architecture, limiting its compatibility with different hardware structures.
  • While AIX has a dedicated atmosphere of software providers, it could have fewer software program alternatives in comparison to more widely used working structures like Linux.

In end, Linux and AIX are two distinct operating systems with their unique characteristics, functions, and use cases. Linux, being open-source, offers versatility, stability, and customization alternatives appropriate for a huge range of computing platforms, from non-public computer systems to servers and embedded structures. It is thought for its robust protection functions, vast software ecosystem, and active community help. On the alternative hand, AIX, as a proprietary Unix-based totally working machine developed through IBM, is optimized for employer-degree environments, specifically IBM Power Systems servers. It provides advanced device management , scalability, reliability, and performance functions tailored for undertaking-critical workloads. The preference among Linux and AIX depends on elements together with the precise necessities of the surroundings, hardware compatibility, to be had skillsets, and budget issues. While Linux may be favored for its flexibility, cost-effectiveness, and vast hardware guide, AIX shines in industries requiring high availability, security, and scalability, such as finance, healthcare, and telecommunications.
