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.

Working with AWS EC2

The AWS Elastic Compute Cloud (EC2) is a scalable computing infrastructure that allows users to lease virtual computing platforms and services to run their cloud applications. AWS EC2 has gained extreme popularity in recent years due to its outstanding performance and scalability combined with relatively cost-effective service plans. This section provides some basic functional knowledge to get you started with deploying and managing AWS EC2 instances running your applications. In particular, we'll introduce you to the following:

  • EC2 instance types – differentiating between various provisioning and related pricing tiers
  • Amazon Machine Images (AMI) – the functional unit required to launch an EC2 instance
  • Accessing your EC2 instances – using SSH to connect and SCP to transfer files to and from your EC2 instances
  • Backing up and restoring your EC2 instances using EBS snapshots
  • Working with the AWS CLI

By the end...
