Mastering Linux Administration

By: Alexandru Calcatinge, Julian Balog

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.

Recent years have seen a significant shift from on-premises computing platforms to private and public clouds. In an ever-changing and accelerating world, deploying and running applications in a highly scalable, efficient, and secure infrastructure is critical for businesses and organizations everywhere. On the other hand, the cost and expertise required to maintain the equivalent level of security and performance with on-premises computing resources become barely justifiable compared to current public cloud offerings. Businesses and teams, small and large, are adopting public cloud services in increasing numbers, albeit large enterprises are relatively slow to make a move.

One of the best metaphors for cloud computing is application services on tap. Do you need more resources for your apps? Just turn on the tap and provision the virtual machines or instances in any number you need (scale horizontally). Or perhaps, for some instances...
