AIX vs Linux: 25 Key Differences You Need to Know(aix和linux的区别)
AIX and Linux are two popular operating systems used by enterprise companies around the world. While they are similar in terms of features and advantages, there are some key differences that set them apart. Read on to learn about the top 25 differences between AIX and Linux that you need to know.
1. Operating Systems: AIX is built on the UNIX operating system, while Linux is built on the Linux kernel and GNU tools.
2. Task Scheduling: AIX operates with a traditional UNIX priority-based task scheduling system, while Linux makes use of a CFS scheduler which schedules tasks by the amount of time each task needs to complete.
3. Platform Support: AIX is only supported on Power Systems and IBM System Z, while Linux is supported on x86, ARM, AVR32, PowerPC, MIPS, PA-RISC, SPARC, and Itanium processors.
4. Security: AIX includes trusted computing features such as Mandatory Access Control, while Linux requires users to configure SELinux and other supplemental security measures in order to secure the OS.
5. Cost: AIX requires an additional license fee, while Linux is typically open-source and available for free.
6. Installation: AIX requires a complex installation procedure, while Linux requires a simple command-line installation.
7. Software Applications: AIX has a limited range of software applications available, while Linux has a wide variety of software applications available.
8. Graphical User Interface: AIX supports the Common Desktop Environment (CDE), while Linux has the option of GNOME, KDE, Xfce, and other graphical user interfaces.
9. Support for Networking: AIX supports IBM s Advanced Programmable Interrupt Controller (APIC), while Linux does not support APIC and relies on Alternative Multiprocessor (AMP) instead.
10. Command Line Interface: AIX has a command line interface (CLI) as well as a graphical user interface (GUI), while Linux only offers the command line interface.
11. System initialization: AIX uses the System Resource Controller (SRC) to initialize a system, while Linux uses the Ubuntu Upstart or Redhat SysVinit daemon to initialize a system.
12. Server Migration: AIX includes a migration toolkit and resources, while Linux requires manual scripting, scripting programs, or open-source migration tools.
13. File System Support: AIX supports multiple file systems such as JFS, type-C, PST, and UNIX file systems, while Linux supports only the Ext2, Ext3, Ext4, ReiserFS, and XFS file systems.
14. Containerization: AIX does not natively support container execution, while Linux supports container technologies such as Docker, Kubernetes, LXC, and LXD.
15. Code Stability: AIX is more stable than Linux in terms of code, for instance AIX does not have to be rebooted due to patches or updates.
16. Software Packaging: AIX makes use of AIX Toolbox for Linux Applications (ATLA) for software packaging, while Linux uses various packaging formats such as RPM, DEB, and Snap packages.
17. Multitasking: AIX implements symmetric multiprocessing (SMP) which allows multiple tasks to be executed at the same time, while Linux implements a preemptive multitasking system.
18. Threading: AIX and Linux both support multithreading, however AIX supports thread-level parallelism while Linux supports both threading and process-level parallelism.
19. Memory Management: AIX uses a segmented paging memory model while Linux uses virtual memory mapping.
20. Source Code: AIX is closed-source, while Linux is open-source.
21. Development Tools: AIX includes IBM s VisualAge suite for development, while Linux supports the GCC compiler and the GNU Make build system.
22. Programming Languages: AIX supports languages such as C, C++, Java, Python, and other UNIX languages, while Linux supports a wide range of programming languages such as C, C++, Java, Python, Perl, Ruby, and Go.
23. Web Servers: AIX supports popular web servers such as Apache and Nginx, while Linux also supports a plethora of web server packages.
24. Controlling Daemons: AIX uses its init (IBM System Resource Controller) process to control any kind of daemon, while Linux can use init, systemd, or upstart to control daemons.
25. Cloud Computing: AIX supports cloud computing with its PowerVM Virtualization System, while Linux supports a wide range of cloud computing platforms such as Amazon Web Services, Microsoft Azure, Google Cloud Platform, and OpenStack.
Overall, AIX and Linux offer both similarities and differences when it comes to the features and capabilities of each operating system. Any company considering a switch from one to the other should familiarize themselves with both architectures to ensure the best possible experience for their users.
