System Design Concepts
Understand the building blocks of scalable systems through interactive simulations and comprehensive explanations. Learn how to design robust, efficient, and maintainable distributed systems.
Load Balancing
Distribute incoming network traffic across multiple servers to ensure no single server becomes overwhelmed. Learn different algorithms like round-robin, weighted, and least connections through interactive visualizations.
Database Sharding
Horizontal database scaling technique that distributes data across multiple database instances. Understand partitioning strategies, shard keys, and managing distributed queries.
Caching Strategies
Improve system performance by storing frequently accessed data in fast storage layers. Explore cache-aside, write-through, write-behind patterns and cache eviction policies.
Microservices Architecture
Design applications as a collection of loosely coupled services. Learn about service decomposition, communication patterns, and managing distributed system complexity.
Message Queues
Asynchronous communication between services using message brokers. Understand pub/sub patterns, message durability, and handling system decoupling at scale.
API Gateway
Single entry point for client requests to microservices. Learn about request routing, authentication, rate limiting, and cross-cutting concerns management.
Content Delivery Networks
Global distribution of static content to reduce latency and improve user experience. Understand edge caching, geographic distribution, and CDN optimization strategies.
Database Replication
Ensure data availability and reliability through master-slave and master-master replication. Learn about consistency models, failover strategies, and conflict resolution.
Rate Limiting
Control the rate of requests to protect systems from abuse and ensure fair usage. Explore token bucket, sliding window, and distributed rate limiting algorithms.
