Overview of this book

Ubuntu Server is taking the server world by storm - and for a good reason! The server-focused spin of Ubuntu is a stable, flexible, and powerful enterprise-class distribution of Linux with a focus on running servers both small and large. Mastering Ubuntu Server is a book that will teach you everything you need to know in order to manage real Ubuntu-based servers in actual production deployments. This book will take you from initial installation to deploying production-ready solutions to empower your small office network, or even a full data center. You'll see examples of running an Ubuntu Server in the cloud, be walked through set up popular applications (such as Nextcloud), host your own websites, and deploy network resources such as DHCP, DNS, and others. You’ll also see how to containerize applications via LXD to maximize efficiency and learn how to build Kubernetes clusters. This new fourth edition updates the popular book to cover Ubuntu 22.04 LTS, which takes advantage of the latest in Linux-based technologies. By the end of this Ubuntu book, you will have gained all the knowledge you need in order to work on real-life Ubuntu Server deployments and become an expert Ubuntu Server administrator who is well versed in its feature set.

Automating Cloud Deployments with Terraform

The previous chapter was especially fun: we were able to deploy Ubuntu in the cloud, utilizing Amazon Web Services (AWS). Deploying infrastructure in the cloud is very powerful and allows us to accomplish things that are not normally possible (or are very tedious) with physical infrastructure. We can spin up Ubuntu instances in minutes, and even set up auto-healing to cover us in situations that would normally result in complete service disruption.

We’ve already explored the concept of automation back in Chapter 15, Automating Server Configuration with Ansible, when we learned about the basics of Ansible. Terraform allows us to take our automation to the next level and even interact with providers such as AWS directly.
