Overview of this book

Discover the power of Oracle Linux 8, the free and enterprise-grade Linux distribution designed for use in any environment, with this recipe-style book. Starting with instructions on how to obtain Oracle Linux for both X86 and ARM-based platforms, this book walks you through various installation methods, from running it as a Windows service to installing it on a Raspberry Pi. It unravels advanced topics such as system upgrades using Leapp for major version transitions and using a PXE server and kickstart files for more advanced installations. The book then delves into swapping kernels to take advantage of Oracle’s UEK, exploring boot options, managing software with DNF, and achieving high availability. Detailed recipes involving security topics will assist with tasks such as data encryption, both at rest and in motion. For developers, it offers guidance on building RPM files, using Docker and Podman in a containerized environment, working with AppStreams, and more. For large-scale deployments, the book introduces Oracle Linux Automation Manager for enterprise-level Ansible utilization, from setting up the Ansible server to basic playbook writing. Finally, you’ll discover strategies for cloud migration. By the end of this book, you’ll possess a comprehensive toolkit that will elevate your skills as a Linux administrator.

Arm'ing for the future of IT – it’s not just a slice of Raspberry Pi

First, let’s chat about Oracle Linux on advanced RISC machines, more commonly known as Arm CPUs. This newer architecture has many advantages over the older x86_64 architecture that Intel and AMD use. This includes lower power consumption; lower latency, enabling better performance; and a simplified architecture that enables higher-density systems. Leveraging Oracle Linux on an Arm system is a popular option for both cloud-scale operators such as Oracle and Microsoft as well as smaller organizations that are looking at reducing their compute power and cooling needs.

Having a single enterprise OS on all Linux systems has several advantages, such as using the same tools across all servers and access to the same commercial support for your systems. The use cases for Arm in your inventory of servers are also interesting. As a whole, Arm processors offer a lower cost due to their higher potential...
