High‑Level Architecture Overview Setting Up Kafka for Production 4.1 Cluster Planning 4.2 Configuration Essentials Designing Python Microservices 5.1 Project Layout 5.2 Dependency Management Producer Implementation Consumer Implementation 7.1 At‑Least‑Once vs Exactly‑Once Semantics Schema Management with Confluent Schema Registry Fault Tolerance & Reliability Patterns Scaling Strategies Monitoring, Tracing, and Observability 12 Security Considerations 13 Deployment: Docker & Kubernetes 14 Real‑World Use Cases 15 Best Practices Checklist 16 Conclusion 17 Resources Introduction In today’s data‑driven world, applications must process billions of events per day, react to user actions in milliseconds, and remain resilient under heavy load. Event‑Driven Architecture (EDA), powered by a robust messaging backbone, has become the de‑facto pattern for building such systems. Apache Kafka—a distributed log platform—offers the durability, throughput, and ordering guarantees needed for real‑time pipelines. Pairing Kafka with Python microservices leverages Python’s expressive syntax, rich ecosystem, and rapid development cycle. ...
