Large-Scale Distributed System Design

Architect systems serving millions of users — load balancing, caching, sharding, and microservices.

Learn to design highly available, fault-tolerant enterprise architectures: Horizontal vs Vertical scaling, Load Balancers (L4 vs L7), Caching strategies (Redis, CDN), Database replication and sharding, CAP Theorem, Message Queues (Kafka, RabbitMQ), Rate Limiting, and Microservices.

What You Will Learn

  • High Availability & Fault Tolerance Architecture Design
  • Distributed Caching Strategies (Cache-Aside, Write-Through)
  • Database Sharding, Partitioning & Master-Replica Topologies
  • CAP Theorem & Distributed Consensus Analysis
  • Asynchronous Event-Driven Architectures (Message Brokers)

Prerequisites & Environment

  • Backend & Database Knowledge
