Let’s Do: DevOps eBook

The DevOps eBook introduces DevOps as a methodology that breaks down silos between development and operations teams to speed up software delivery, improve stability, and foster continuous improvement. It begins with foundational concepts like Agile, behaviour-driven development (BDD) using tools like Cucumber and Selenium, and then delves into practical tutorials—especially around using Ansible for configuration management, deployment of applications (e.g. LAMP, WordPress), monitoring tools, load balancing, VM provisioning, and managing database setups. Many chapters provide step-by-step guides for deploying real-world services (e.g., RabbitMQ, Graphite, Jenkins) and emphasize security hardening, infrastructure as code, and maintaining environments for efficiency and reliability.
