This book is about techniques that help us architect software in a better and more efficient way: With microservices packed as immutable containers, then tested and deployed continuously to servers that are automatically provisioned with configuration management tools. It's about fast, reliable and continuous deployments with zero-downtime and the ability to roll-back. It's about scaling to any number of servers, designing self-healing systems capable of recovering from both hardware and software failures, and about centralized logging and monitoring of a cluster. We will cover some of the latest and greatest practices and a variety of tools such as: Docker, Kubernetes, Ansible, Ubuntu, Docker Swarm, Docker Compose, and Consul.
