Master System Design Concepts with Microsoft Engineer | Udemy

Learn System Design from Someone Who’s Built Systems at Scale

Are you preparing for software engineering interviews at top tech companies? Want to understand how applications scale from a few users to millions? This course teaches you system design through the lens of real-world distributed systems.

This isn’t a collection of short, surface-level videos for entertainment. This is a comprehensive, structured learning experience designed to build genuine understanding. Each lesson is carefully crafted to help you truly master the concepts, not just memorize them for an interview.

I’m a Software Engineer at Microsoft with over 5 years of experience working on the backend infrastructure of Microsoft Teams, a platform serving hundreds of millions of users daily. I’ve designed this course to teach you not just the theory, but the practical reasoning behind system design decisions.

What You’ll Learn:

System Design Fundamentals

• How to scale applications from 0 to a million users
• Performance trade-offs: latency vs throughput, vertical vs horizontal scaling
• Back-of-the-envelope calculations for system sizing
• Message queues and event-driven architectures

Networking & Traffic Management

• Core protocols: TCP, UDP, HTTP, and gRPC
• DNS and routing mechanisms
• API design patterns (REST, RPC, versioning)
• Load balancers, proxies, and API gateways

Service Architecture

• When to use microservices (and when not to)
• API Gateways

Databases & Data Architecture

• SQL vs NoSQL: choosing the right database
• CAP theorem in practice
• Indexing, replication, and sharding strategies
• Consistent hashing

Distributed Systems Concepts

• Designing for fault tolerance and high availability
• Understanding latency percentiles (p90, p95, p99)
