About this book:

This book provides a comprehensive guide to modern DevOps and CI/CD practices, specifically tailored for the distinct requirements of web and mobile application development. It begins by establishing a cultural foundation centered on automation, collaboration, and end-to-end responsibility. The technical core of the book details the construction of robust pipelines, moving from version control and branching strategies to specialized build processes—such as iOS code signing, Android Gradle builds, and web asset bundling. Throughout these stages, the text emphasizes the necessity of immutable artifacts and reproducible builds to ensure that software tested in staging is identical to what reaches the end-user.

The second half of the book focuses on sophisticated delivery and operational resilience. It explores advanced deployment patterns like blue-green and canary releases, along with the use of feature flags to decouple code deployment from feature release. A significant portion is dedicated to Infrastructure as Code (IaC) using tools like Terraform and Packer, allowing teams to manage environments with the same rigor as application code. The book also integrates security into the pipeline through automated scanning and the management of Software Bills of Materials (SBOMs), advocating for a "shift-left" approach to identify vulnerabilities early in the development lifecycle.

Finally, the book addresses the long-term management of high-performing systems through the lens of observability and Reliability Engineering. By implementing metrics, logs, and distributed tracing, teams can define Service Level Objectives (SLOs) and manage error budgets to balance innovation with stability. The text concludes by discussing the complexities of scaling CI/CD across monorepos, multi-repo structures, and multi-cloud environments, while maintaining a focus on developer productivity and cost-efficiency. Practical reference architectures and migration paths provide a roadmap for organizations transitioning from manual processes to a fully automated, resilient delivery ecosystem.

What You'll Find Inside:

• End-to-end CI/CD pipeline design for web and mobile platforms, including platform-specific build processes for iOS (code signing/provisioning) and Android (Gradle/keystores) with artifact management strategies
• Implementation of core DevOps practices: Infrastructure as Code (Terraform), configuration management (Ansible/Packer), containerization for immutable builds, and pipelines-as-code for reproducible, scalable delivery
• Advanced deployment patterns including blue-green, canary releases, and feature flags to enable safe progressive delivery with automated rollback capabilities and risk mitigation
• Comprehensive observability, security, and reliability engineering coverage: metrics/logs/traces, SLOs/error budgets, secrets management, SBOMs, and incident response for production system health
• Scaling strategies for complex environments: monorepo vs multi-repo tradeoffs, multi-cloud deployments, and optimization techniques for cost, performance, and developer productivity in CI/CD systems

Who's It For:

This book is ideal for DevOps engineers, platform teams, and software developers responsible for building, testing, and deploying web and mobile applications. It provides practical guidance for implementing end-to-end CI/CD pipelines with platform-specific considerations for iOS and Android, making it valuable for mobile developers seeking to master app store distribution processes, backend engineers working with microservices and containers, and technical leaders aiming to establish reliable, secure, and efficient software delivery systems. Readers should have foundational knowledge of software development and basic version control concepts to fully benefit from the advanced topics covered.
