Most software engineers can build features. Far fewer can design the entire platform behind them, end-to-end, in production. Cloud architecture has become the defining skill of a senior engineer, yet most resources teach it in fragments, leaving you to assemble the full picture on your own.
Drawing on decades of enterprise architecture experience, the authors provide a complete, end-to-end blueprint. You begin with the foundations: core pillars (availability, performance, security, observability, cost, and sustainability), design patterns, methods, technology selection, and adaptive architecture, taught through one running case study, Aethera Airlines. Then you design nine real-world systems from the ground up: UPI payments, a trading platform, OTT streaming, a collaborative document editor, an agentic LLM-powered recommendation engine, plus chat, social media, ride-sharing, and a URL shortener. Throughout, you apply domain-driven design, API-first thinking, capacity planning, and multi-cloud cost trade-offs, with hands-on exercises and design challenges for each of the nine systems.
By the end, you will think and build like a cloud architect: engineering fault-tolerant, secure, and observable platforms on any major cloud, and ready for senior system design interviews at top tech companies.
WHAT YOU WILL LEARN
● Build nine real-world cloud systems end-to-end.
● Design payments, trading, streaming, and agentic AI systems.
● Apply DDD, API-first design, and proven cloud-native patterns.
● Engineer security, fault tolerance, scalability, and cost control.
● Prepare for system design interviews with hands-on exercises.
WHO THIS BOOK IS FOR
This book is for software engineers, cloud developers, system architects, and technical leaders who want to master full-lifecycle cloud architecture. It is equally valuable for final-year computer science students targeting campus placements and professionals preparing for senior system design interviews on major cloud platforms.
