Part 2: Load Balancing Strategies

Explore different load balancing algorithms (round-robin, least connections, weighted), health checks, and session persistence. Understand when to use hardware vs. software load balancers.

Part 3: Caching Strategies

Deep dive into caching patterns: cache-aside, write-through, write-behind, and refresh-ahead. Learn about cache invalidation, eviction policies, and distributed caching systems like Redis and Memcached.

Part 4: Database Sharding

Master horizontal partitioning strategies, shard key selection, and cross-shard queries. Understand consistent hashing and its role in distributed databases.

Part 5: Replication and Consistency

Learn about master-slave replication, master-master replication, and eventual consistency. Explore the CAP theorem and its implications for distributed systems.

Part 6: API Design and Rate Limiting

Design RESTful and GraphQL APIs, implement rate limiting strategies, and handle API versioning. Understand throttling, quotas, and API gateway patterns.

Part 7: Message Queues and Event-Driven Architecture

Implement asynchronous processing with message queues. Learn about pub/sub patterns, message ordering, and handling failures in distributed messaging systems.

Part 8: Microservices Architecture

Design service boundaries, implement service discovery, and handle inter-service communication. Learn about API gateways, service mesh, and distributed tracing.

Part 9: Distributed Systems Patterns

Explore patterns like circuit breakers, bulkheads, and retries. Understand distributed locks, leader election, and consensus algorithms.

Part 10: Search and Indexing

Design search systems using inverted indexes, implement full-text search, and understand ranking algorithms. Learn about Elasticsearch and Solr.

Part 11: Content Delivery Networks (CDN)

Understand CDN architecture, edge caching, and geographic distribution. Learn when and how to use CDNs for static and dynamic content.

Part 12: Monitoring and Observability

Implement comprehensive monitoring with metrics, logs, and traces. Learn about SLIs, SLOs, and error budgets. Understand distributed tracing and APM tools.

Part 13: Security in Distributed Systems

Implement authentication and authorization across services. Learn about OAuth 2.0, JWT tokens, and service-to-service authentication. Understand security best practices.

Part 14: Scalability Patterns

Design for horizontal and vertical scaling. Understand auto-scaling, capacity planning, and performance optimization techniques. Learn about database scaling strategies.

Part 15: Real-World Case Studies

Analyze system designs for popular services: URL shortener, chat system, video streaming, social media feed, and notification system. Apply all learned concepts to practical scenarios.
