Once the high-level flow is established, zoom into specific components to detail how they handle data. This involves defining specific API endpoints (REST or gRPC), configuring message queues (like Kafka or RabbitMQ) for asynchronous processing, and detailing cache eviction policies (LRU) to optimize read speeds. 6.
