Mastering Ubuntu Server: Administer, secure, automate, and scale Ubuntu Server 26.04 for cloud, containers, and AI workloads

Ubuntu Server is a stable, flexible, and powerful Linux distribution used in environments ranging from individual servers to large-scale infrastructure. Mastering Ubuntu Server, Fifth Edition gives you the practical knowledge needed to administer Ubuntu Server 26.04 deployments confidently.

Starting with installation, essential commands, users, permissions, packages, processes, storage, and networking, the book builds a strong foundation in everyday server administration. You will then configure DHCP, DNS, internet gateways, Samba, NFS, MariaDB, Apache, NGINX, and Nextcloud, before working with QEMU/KVM, LXD, Docker, and MicroK8s. This updated edition expands into modern infrastructure practices, showing you how to automate configuration with Ansible, deploy and scale Ubuntu on AWS EC2, and provision AWS resources with Terraform. You will also serve local AI models with Lemonade, isolate agent workloads with AI Lab, manage Ubuntu fleets at scale with Landscape, and explore Canonical Academy's SysAdmin qualification. Finally, you will apply practical security, vulnerability management, troubleshooting, backup, and disaster recovery techniques.

By the end of this book, you will be able to administer, secure, automate, troubleshoot, and scale Ubuntu Server across on-premises, virtualized, containerized, and AWS environments.
