Caching, Messaging, and Real-Time Systems is a hands-on course designed to teach you the core tools behind scalable modern platforms. It’s ideal for developers who want to build fast systems, event-driven services, and real-time user experiences.

• Learn in-memory caching principles and when to use Redis vs Memcached

• Use Redis data structures (strings, lists, sets, hashes, sorted sets)

• Apply caching strategies (TTL, LRU, write-through, write-back)

• Build real features: session storage, rate limiting, caching DB queries

• Understand Pub/Sub and event-driven patterns

• Build queue systems using RabbitMQ (exchanges, routing, acknowledgments)

• Learn Kafka fundamentals (topics, partitions, consumer groups)

• Build real-time apps with WebSockets / Socket.IO (rooms, namespaces)

• Scale real-time servers using Redis/message brokers, and compare SSE vs WebSocket

• Hands-on: chat notifications, task processing, streaming producer/consumer, live dashboard

No random tutorials—just the real backend tools that power modern apps. By the end, you’ll be able to build event-driven and real-time systems that scale.
