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.

Summary

AWS and Azure provide a roughly similar set of features for flexible compute capacity, storage, and networking, with pay-as-you-go pricing. They share the essential elements of a public cloud – elasticity, autoscaling, provisioning with self-service, security, and identity access management. This chapter explored both cloud providers strictly from a practical vantage point, focusing on typical deployment and management aspects of everyday cloud administration tasks.

We covered topics such as launching and terminating a new instance or virtual machine. We looked at resizing an instance to accommodate a higher or lower compute capacity and scaling the storage by creating and attaching additional block devices (volumes). Finally, we used CLI tools for scripting various cloud management workloads.

At this point, you should be familiar with the AWS and Azure web administration consoles and CLI tools. You have learned the basics of some typical cloud management tasks...
