How Samsung achieved real-time pricing with AWS Lambda Response Streaming
Samsung achieved real-time pricing on their high-traffic ecommerce site by replacing their legacy stateful Data Aggregation (DA) architecture with a stateless streaming solution using AWS Lambda Response Streaming and Amazon CloudFront edge caching. This eliminated a 1-hour desynchronization gap between the authoritative pricing engine and customer-facing pages, allowing for immediate price updates and reduced cart shock. The new architecture uses a Pass-Through pattern, streaming responses directly from the Pricing Engine to the client without buffering, resulting in improved latency and responsiveness.
