System Design 2026: Master the 25 Case Studies That Get You Hired

Accelerate your engineering career with System Design 2026 — a focused, case-study-driven guide that prepares you for real technical interviews and real-world architectural challenges. Instead of abstract theory, this book walks you through 25 modern, practical, and high-impact system design case studies — the kind companies actually test for and build in production.

Designed for software engineers, backend developers, and aspiring architects, this handbook gives you the clarity, confidence, and architectural thinking needed to perform at a senior level.

Inside, you’ll explore:
→ The system design mindset and how interviewers evaluate your decisions
→ Trade-off analysis, capacity planning, and requirement scoping
→ Designing scalable, reliable, and cost-efficient systems
→ Real-time data processing, event-driven architectures, and message queues
→ Database modeling, sharding, replication, and storage choices
→ Caching layers, CDNs, and high-throughput optimization
→ Microservices, APIs, load balancing, and distributed coordination
→ Observability, monitoring, and failover strategies for production systems
→ Security, rate limiting, and traffic management essentials

You’ll master 25 full case studies, including:
→ Designing a global video streaming platform
→ Real-time chat and messaging architectures
→ Social media news feed and recommendation systems
→ Ride-hailing and delivery platform backends
→ Scalable search systems with indexing and ranking
→ E-commerce platforms with inventory and checkout flows
→ URL shorteners, rate limiters, and file storage services
→ IoT ingestion pipelines processing millions of events
→ AI-augmented search engines and RAG-powered knowledge tools
→ Multi-region, fault-tolerant financial transaction systems

Each case study includes:
→ A structured breakdown of functional and non-functional requirements
→ Architecture diagrams and component explanations
→ Step-by-step reasoning and trade-off evaluation
→ Deep dives into databases, queues, caches, and compute layers
→ Real-world pitfalls and how to avoid them
→ What interviewers expect you to highlight and how to stand out

By the end of this book, you’ll think and communicate like a seasoned systems architect — able to solve complex design problems, ace high-stakes interviews, and build systems ready for global scale.
