Personalized media recommendations at scale: Architecting the future of content discovery

Ponnekanti, Sai Kaushik (2025) Personalized media recommendations at scale: Architecting the future of content discovery. World Journal of Advanced Engineering Technology and Sciences, 15 (1). pp. 1233-1242. ISSN 2582-8266

Personalized media recommendation systems have transformed content discovery across streaming platforms, serving tailored suggestions to millions of concurrent users. These systems leverage sophisticated data architectures, collaborative filtering algorithms, content-based methods, and hybrid approaches to deliver relevant recommendations at scale. The infrastructure supporting these recommendations encompasses unified data platforms, distributed computing architectures, intelligent caching strategies, microservices, and real-time model updates. While these systems continue to evolve in sophistication and effectiveness, they face persistent challenges, including filter bubbles, explainability issues, privacy concerns, and content distribution inequities. Future directions point toward multi-objective optimization, federated learning, enhanced contextual awareness, and cross-platform personalization to balance competing stakeholder interests.
