CoreOS in Action

• User friendly book
• Offers solid and practical information
• Plenty of real-world examples
• Fully explains how and why CoreOS operates

Traditional Linux server distributions include every component required for anything you might be hosting, most of which you don't need if you've containerized your apps and services. CoreOS Container Linux is a bare-bones distro with only the essential bits needed to run containers like Docker. Container Linux is a fast, secure base layer for any container-centric distributed application, including microservices. And say goodbye to patch scheduling; when Container Linux needs an update, you just hot-swap the whole OS.

CoreOS is an operating system designed from the ground up to facilitate container use at any scale. It is fault-tolerant, extremely lightweight, and highly performant. CoreOS is designed to solve a company's scale, availability, and deployment workflow problems.

To be competitive, an organization needs to reach modern standards of scalability and high availability. While Linux is an option, it's painful to deal with the frequent operating system updates and complex configuration management. Docker, a popular container system, can reduce these manual system administration tasks. While plenty of Linux distributions support Docker, they do not handle large scale production.

This is where CoreOS can help. CoreOS is an operating system designed from the ground up to facilitate container use at any scale.

CoreOS in Action begins by introducing the core components, how services run in CoreOS, and the big picture of how the parts fits together. Next, readers learn how to fire up their own CoreOS cluster. Readers learn how to configure their local environment, the basics of CoreOS system administration, and follow an application deployment example.

It covers how to take advantage of CoreOS's high availability and fault tolerance as well as how to plan application architecture. The book also covers operational planning for CoreOS, deployment options, and how to deal with mass storage.
Readers will discover end-to-end deployment of CoreOS in Amazon Web Services, and learn from real-world examples of application stacks.

This book is for operations professionals, site reliability engineers, systems architects, or anyone who wants to learn to deploy CoreOS.
