What We’re Building Today

Today you’ll deploy a production-grade distributed log streaming platform that forms the backbone of modern event-driven architectures. By the end of this lesson, you’ll have:

  • Multi-broker Kafka cluster with 3 nodes configured for high availability and fault tolerance

  • Partitioned topic architecture supporting parallel log processing at 50,000+ events per second

  • Comprehensive monitoring stack with real-time metrics for throughput, latency, and consumer lag

  • Automated health checking system that validates cluster state and triggers alerts on degradation

  • Load testing framework simulating production traffic patterns with configurable throughput profiles
