Ship faster and more reliably — the culture, practices, and pipeline behind modern software delivery.

Welcome to DevOps: Culture, Automation, and Continuous Delivery.

DevOps unites development and operations so teams deliver change quickly, reliably, and continuously. This free book teaches it as both culture and practice: the principles and lifecycle, version control and collaboration, continuous integration and continuous delivery/deployment, infrastructure as code, monitoring and observability, reliability with SRE and error budgets, security woven in as DevSecOps, and the DORA metrics that prove it works. Ten focused chapters with real pipeline and IaC examples and clear diagrams. Tools like Docker and Kubernetes are servants of these practices — learn the practices, and you'll understand how modern software is built and run.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.
