Overview of this book

Linux plays a significant role in modern data center management and provides great versatility in deploying and managing your workloads on-premises and in the cloud. This book covers the important topics you need to know about for your everyday Linux administration tasks. The book starts by helping you understand the Linux command line and how to work with files, packages, and filesystems. You'll then begin administering network services and hardening security, and learn about cloud computing, containers, and orchestration. Once you've learned how to work with the command line, you'll explore the essential Linux commands for managing users, processes, and daemons and discover how to secure your Linux environment using application security frameworks and firewall managers. As you advance through the chapters, you'll work with containers, hypervisors, virtual machines, Ansible, and Kubernetes. You'll also learn how to deploy Linux to the cloud using AWS and Azure. By the end of this Linux book, you'll be well-versed with Linux and have mastered everyday administrative tasks using workflows spanning from on-premises to the cloud. If you also find yourself adopting DevOps practices in the process, we'll consider our mission accomplished.

We began this chapter with a high-level overview of the Kubernetes architecture and API object model, introducing the most common cluster resources, such as Pods, deployments, and Services. Next, we took on the relatively challenging task of building an on-premises Kubernetes cluster from scratch using virtual machines. As we became more familiar with Kubernetes internals in general, we moved to the cloud, working with the EKS and AKS managed cluster services from AWS and Azure. We explored various CLI tools for managing Kubernetes cluster resources in the cloud and on-premises. At the highpoint of our journey, we focused on deploying and scaling applications in Kubernetes using imperative and declarative deployment scenarios.

We believe that novice Linux administrators will benefit greatly from the material covered in this chapter and become more knowledgeable in managing resources across hybrid clouds and on-premises distributed environments, deploying applications at...
