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.

The CSPs that offer PaaS solutions are mostly the same as those that offer IaaS solutions. We have Amazon, Microsoft, and Google as the major PaaS providers.

Amazon offers the Elastic Beanstalk service, whose interface is straightforward and simple. You can create a sample application or upload your own, and Beanstalk takes care of the rest, from deployment details to load balancing, scaling, and monitoring. You select the AWS EC2 hardware instances to deploy on. Next, we will discuss another major player's offering: Google App Engine.
