What is the AIX Operating System? 

AIX, short for Advanced Interactive eXecutive, is a set of complete Unix operating systems (OS) created and marketed by IBM for multiple computer platforms. AIX is famous for its durability, scalability, and reliability, which has made it a favoured option for corporate settings. It efficiently works with IBM's hardware and software environment. Additionally, it offers robust system management, security, and application performance capabilities, as detailed in the AIX Commands Cheat Sheet.
 

What is Solaris Operating System? 

Solaris is another robust Unix-based operating system created by Sun Microsystems and is now a part of Oracle Corporation. It is best known for its SPARC and x89 support, scalability, and security. Some of its innovative features include DTrace (Dynamic Tracing Framework) and ZFS (Zettabyte File System). Moreover, its stability and performance make it vital for enterprise environments.

Differences Between AIX and Solaris 

Let’s know some of the differences between Advanced Interactive eXecutive (AIX) and Solaris in depth:
 

1) Installation 

The installation process of AIX and Solaris varies significantly. AIX offers a simple installation process that integrates seamlessly with IBM hardware. Thus, making it straightforward for system administrators to set up new systems. The AIX installer provides a guided setup with options for beginners and advanced users ensuring the installation process is user-friendly and comprehensive. 

On the other hand, Solaris provides a flexible and powerful installation process with various installation methods, such as interactive, automated (JumpStart/AI), and network installations. Solaris installations can be highly customised to meet specific deployment needs. They also benefit complex environments but may require more expertise than AIX. 

2) Packaging 

AIX uses the RPM Package Manager (RPM) for software management, which is well-known for its reliability and ease of use. RPM allows for easy installation, updating, and removal of software packages. Thus, ensuring that system administrators can maintain software consistency across AIX systems. Additionally, AIX supports using the Network Installation Manager (NIM) to manage software distribution across multiple systems. 

Solaris, on the other hand, uses the Image Packaging System (IPS) for software management. It offers advanced features like automatic dependency resolution, incremental updates, and rollback capabilities. IPS simplifies maintaining large-scale deployments by ensuring that all software packages are up-to-date and secure. 

3) System Configuration 

AIX provides rich system configuration tools designed to work seamlessly with IBM hardware. The System Management Interface Tool (SMIT) is a powerful utility with a graphical interface for managing system configurations. It makes it easier for administrators to perform complex tasks without extensive command-line knowledge.  

AIX also supports various file formatting and scripts for advanced system customisation. Solaris offers complete system configuration options through tools like the Service Management Facility (SMF) and the Solaris Management Console (SMC). SMF provides a framework for managing system services, ensuring that services are configured consistently and can be easily monitored and controlled.  

SMC offers a graphical interface for handling system configurations, similar to AIX's SMIT. However, it comes with additional capabilities for managing complex networked environments. 

4) Storage Management 

Storage management is a vital aspect of any operating system, and both AIX and Solaris offer advanced features to address this need. AIX includes the Logical Volume Manager (LVM) and IBM's General Parallel File System (GPFS) for managing storage resources. LVM allows for flexible and efficient disk space allocation. The GPFS provides high-performance, scalable file system capabilities for large-scale environments. 

Solaris is renowned for its Zettabyte File System (ZFS), which offers a revolutionary approach to storage management. ZFS combines traditional file system and volume manager functionalities, providing features like data integrity checking, snapshot and cloning capabilities, and seamless scalability. It is perfect for environments requiring high data protection and storage efficiency. 

5) Security Measures 

Security is a top priority for both AIX and Solaris, and each operating system offers a range of features to protect against threats. AIX includes the AIX Security Expert tool, which provides a focused interface for configuring security settings and policies. It also supports new security features, such as role-based access control (RBAC), encrypted file systems, and integrated intrusion detection and prevention systems. 

Solaris offers a robust security framework with features like Solaris Trusted Extensions. It also provides enhanced security controls for multilevel security environments. Solaris supports RBAC, encryption, and thorough auditing capabilities. Solaris' built-in security features are designed to meet strict security requirements. Thus, making it a popular choice for environments that demand high levels of data protection.

6) Virtualisation 

The modern operating systems have virtualisation features. Both Solaris and AIX have this special feature. AIX has PowerVM virtualisation technology that creates virtual machines and logically partitions the IBM hardware. Some of the advanced features include integrated management tools, dynamic resource allocation, and partition mobility. Due to its capabilities, it’s an ideal solution for enterprises.   

On the other hand, Solaris also offers virtualisation capabilities using Solaris Zones. It creates a lightweight, isolated environment to promote efficient resource utilisation and simplified management. Oracle VM offers hardware virtualisation to create virtual machines. Some of the advanced features include dynamic resource allocation and migration.  

7) Networking

Networking capabilities are essential for any operating system, and both AIX and Solaris offer robust networking features. AIX includes advanced networking tools like the AIX Network Installation Manager (NIM) and IBM's High-Availability Cluster Multi-Processing (HACMP) software. These tools provide powerful networking capabilities for managing complex networked environments and ensuring high availability and reliability. However, the specific networking tools and features offered are often a point of comparison when considering AIX vs Linux, as Linux also provides a comprehensive suite of networking utilities. 

Solaris offers a broad set of networking features, including support for advanced protocols, network virtualisation, and integrated network management tools. The Crossbow network virtualisation technology in Solaris allows the making of virtual network interfaces and switches, enabling efficient resource allocation and management.  Solaris also includes advanced networking capabilities like IP Multipathing (IPMP) and sun cluster for high-availability networking.
