Event-Driven Mastery: Designing Low-Latency Real-Time Systems at Scale
Harnessing WebSockets, Kafka, and Redis to build responsive experiences that handle millions of concurrent events.
Real-time isn't just for chat apps anymore. From collaborative dashboards to financial trading, users expect instantaneous feedback across all digital platforms.
Building for real-time at scale requires a departure from traditional Request-Response cycles. Event-driven architectures allow for high-throughput, decoupled communication.
In this deep dive, we compare different message brokers like Kafka and RabbitMQ, and look at how Redis Pub/Sub can be used for ultra-low latency signaling.
Managing WebSocket connections across a distributed fleet of servers introduces challenges in session persistence and load balancing.
We share our playbooks for building resilient, event-sourced systems that remain consistent even under extreme load spikes.
