Overview of this book

The Linux DevOps Handbook is a comprehensive resource that caters to both novice and experienced professionals, ensuring a strong foundation in Linux. This book will help you understand how Linux serves as a cornerstone of DevOps, offering the flexibility, stability, and scalability essential for modern software development and operations. You’ll begin by covering Linux distributions, intermediate Linux concepts, and shell scripting to get to grips with automating tasks and streamlining workflows. You’ll then progress to mastering essential day-to-day tools for DevOps tasks. As you learn networking in Linux, you’ll be equipped with connection establishment and troubleshooting skills. You’ll also learn how to use Git for collaboration and efficient code management. The book guides you through Docker concepts for optimizing your DevOps workflows and moves on to advanced DevOps practices, such as monitoring, tracing, and distributed logging. You’ll work with Terraform and GitHub to implement continuous integration (CI)/continuous deployment (CD) pipelines and employ Atlantis for automated software delivery. Additionally, you’ll identify common DevOps pitfalls and strategies to avoid them. By the end of this book, you’ll have built a solid foundation in Linux fundamentals, practical tools, and advanced practices, all contributing to your enhanced Linux skills and successful DevOps implementation.

ISO/OSI as a networking standard

The starting point of any discussion about networks always starts with the reference model defined by the International Organization for Standardization/Open Systems Interconnection (ISO/OSI). The ISO/OSI reference model is a conceptual model that defines a networking framework to implement protocols in seven layers. It is a framework that allows us to view communications between systems (computer or otherwise) as separate from the actual physical and software structure underlying it.

In Linux, the OSI model is implemented through a series of software components that are responsible for performing the functions of each layer. These components work together to enable networking capabilities in Linux.

The seven layers of the OSI model that are implemented in Linux are as follows:

  • Physical
  • Data link
  • Network
  • Transport
  • Session
  • Presentation
  • Application

In a system running in the cloud, you will have access to all...
