Get to know the AIX operating system!

Operating systems from the UNIX family are known for their high reliability and performance. This is why many companies use such systems to manage key application servers. One of the systems that belongs to this family is AIX, which has gained popularity in recent years due to its significant potential for virtualization as well as the fact that its security configuration meets the strictest security requirements. From this book, you will learn how the AIX operating system works and how to work with it as an administrator. You will learn the best practices. Further, you will learn about the way PowerVM, one of the most flexible and most reliable virtualization solutions, works. You will also learn numerous ways to ensure the security of both the operating system and the applications operating under its control.

The strength of AIX lies not only in the design of the operating system itself, but also in the hardware platform that it works on, namely IBM Power Systems servers. These servers are based on POWER processors (currently Power8 and Power9) and they outperform the x86 family. Indeed, many benchmarks confirm the high performance of POWER processor-based servers.

This book is for people who want to administer UNIX systems. It describes the AIX system, its design, and its operating principles. It is based on AIX 7.2, but in many places, it also describes the differences between that version and previous ones. This provides readers with up-to-date knowledge about this release of AIX as well as earlier releases. Most of the described features of the system will remain current (for many years) in subsequent releases. The book describes the features of the system and provides guidance for administrators on how to perform specific operations using the system as well as the consequences of such operations.

The book is made up of chapters featuring content that requires the reader to have various levels of knowledge. The majority of chapters require only basic knowledge of UNIX or LINUX and computer networking, which makes them suitable for beginners. However, to understand the chapter on virtualization, the reader should have a general understanding of operating system virtualization. Moreover, the security chapter presents issues that will be most easily understood by people with intermediate or advanced knowledge of AIX.

The topics covered include:

- Basics of the AIX operating system;
- Virtualization, PowerVM, Virtual I/O Server;
- Installation and maintenance of the AIX operating system;
- Management of users, disks, and the file system;
- Backup and system diagnostics;
- Network, security, and performance management;
- IBM Power platform.
