System Design Basics: Scalable Architecture for Interviews

Tackling a system design interview can feel overwhelming when you are transitioning from writing code to architecting entire systems. Understanding how large-scale applications operate under the hood is a crucial step in advancing your software engineering career. This course breaks down the complexities of distributed systems into manageable, easy-to-understand concepts. You will transition from basic programming knowledge to understanding how to design robust, scalable, and highly available architectures using modern industry standards. What you'll learn: • Understand foundational system design terminology, including latency, throughput, and availability. • Learn how to scale databases using partitioning, sharding, and replication techniques. • Explore modern architectural patterns like microservices, API gateways, and event-driven design. • Apply caching strategies and load balancing to optimize system performance. • Design scalable architectures for common real-world applications through guided written exercises. • Practice structured frameworks for approaching and solving system design interview questions. The course begins with essential terminology and basic networking concepts before moving into data storage, scaling strategies, and modern cloud-native patterns. You will follow a logical progression through written explanations and architectural case studies, building up to full system design scenarios. Designed for beginner to intermediate software engineers, this text-based course requires no prior system design experience, just a basic understanding of programming and web applications.
