Chapter 6. Data Storage and Retrieval for Multimodal AI

If you’re thinking we’re going to talk about passive backend storage systems, you’re in for a ride.

With storage and retrieval serving as the cognitive scaffold of multimodal AI applications, storage is anything but passive.

As enterprises move toward agentic systems that perceive, reason, and act across modalities, the infrastructure that powers these systems must evolve. This chapter explores the architectural underpinnings of data storage and retrieval in large-scale multimodal AI environments, focusing on the demands of heterogeneity, latency, semantic recall, and cross-modal reasoning.

We follow the journey of TelMo, a fictional telecom leader that is building autonomous network intelligence, to explore how cloud-native storage tiers, vector and graph databases, and caching strategies power real-time, cross-modal AI workloads. From structured KPIs to drone footage, every byte is retrievable with purpose.

By the end, you’ll have a blueprint for implementing a hybrid, modality-aware storage and retrieval system designed for scale and intelligence. In the playbook, you’ll build a graph-augmented retrieval engine and edge-aware caching layer that simulates how real-world AI agents retrieve, enrich, and reuse multimodal information across time, region, and operational context.
