Lambda Architecture elegantly solves the fundamental dilemma of big data processing: the conflict between speed and accuracy. Consider Twitter's trending topics system - it must show what's trending right now, but also ensure accuracy across billions of tweets. The architecture achieves this through three layers: batch, speed, and serving. The batch layer, like Hadoop clusters processing Twitter's tweet archives, handles the complete dataset with high accuracy but high latency. Meanwhile, the speed layer, implemented using Apache Storm or Kafka Streams, processes only recent data with lower accuracy but near real-time results. Finally, the serving layer, often using databases like Cassandra or HBase, merges these views to provide a comprehensive result.
