Designing end-to-end real-time inference platforms: From data to decision

This article presents a comprehensive framework for designing end-to-end real-time inference platforms that enable organizations to deliver personalized experiences and make intelligent decisions within milliseconds. It explores the architectural components essential for supporting hundreds of concurrent models while maintaining sub-second latency, from data pipelines and feature engineering to model serving and performance optimization. The discussion encompasses hybrid batch-stream processing, feature stores, Kubernetes orchestration, latency optimization techniques, and cross-functional collaboration practices. By addressing both technical infrastructure and organizational considerations, the article provides engineering leaders, MLOps practitioners, and platform architects with practical guidance for creating resilient AI systems that align with business objectives and deliver measurable value to end users across industries such as e-commerce, finance, media, and healthcare.
