System Design
A practical roadmap for system design fundamentals. Start with traffic distribution, then move into data access, caching, and scale patterns.
What is System Design
Understand how system design helps you build scalable, reliable, and maintainable applications in real-world production environments.
Functional vs Non-Functional Requirements
Learn the difference between functional and non-functional requirements and how they shape real-world system design decisions.
Latency vs Throughput
Understand the difference between latency and throughput and how they impact performance and scalability in real-world systems.
Availability vs Consistency
Learn the trade-off between availability and consistency and how it impacts real-world distributed systems.
Scalability Basics (Vertical vs Horizontal)
Learn how vertical and horizontal scaling work, when to use each, and how they impact real-world system performance.
Load Balancing
Learn how load balancing distributes traffic across servers to improve scalability, reliability, and performance in real systems.
Caching
Reduce latency and offload repeated work by storing expensive results closer to the consumer.
Databases
Learn different types of databases, when to use them, and how they impact scalability, performance, and system design decisions.
Database Indexing
Speed up lookups by creating the right indexes, then balance read performance against write amplification and storage cost.
Database Replication
Learn how database replication improves availability, scalability, and reliability with practical patterns and real-world examples.
Database Sharding
Learn how database sharding distributes data across multiple databases to handle large scale traffic and improve performance.
