Load Balancers : System Design Interview Roadmap - E-Book
Part I: Traffic Management Series, System Design in Depth
Master Load Balancers and Unlock $300K+ Infrastructure Engineering Careers
Transform from knowing "what" load balancers do to understanding "why" and "how" to implement them at scale. This isn't another theoretical guide—it's a practical roadmap with real code, performance benchmarks, and actual system design scenarios from FAANG interviews.
What makes this different:
Real-world case studies: Learn from ShopMart's $2.3M Black Friday crash and how competitors gained 23% market share
Hands-on implementation: Build working load balancers from scratch with full code examples
Production-ready knowledge: Scale from 1K to 1M+ users with concrete capacity planning
Career acceleration: Master system design interviews at top tech companies
Technology comparison: Navigate HAProxy vs AWS ALB vs F5 with real cost analysis
Stop being the engineer who knows load balancers exist. Become the architect who designs systems handling millions of users.
Book Summary
This comprehensive guide takes you from load balancer basics to enterprise-scale implementations through practical, hands-on learning. Starting with real failure scenarios (like e-commerce crashes costing millions), it builds understanding through working code examples, production deployment strategies, and advanced optimization techniques.
The book emphasizes practical application over theory, providing actual performance metrics, cost analyses, and troubleshooting scenarios. Each chapter builds systematically: from understanding core problems to implementing solutions, scaling for production, choosing appropriate technologies, and mastering advanced patterns.
The final section prepares readers for technical interviews with system design scenarios, troubleshooting problems, and career positioning strategies, making it valuable for both learning and career advancement.
