1. Understanding Edge and Distributed Infrastructure
Edge infrastructure refers to compute and storage resources placed near the point of data generation. Unlike traditional cloud-centric models, where all data is transmitted to distant hyperscale data centers, edge computing processes data locally, delivering faster responses and reducing network congestion.
Key Characteristics
Proximity to Data Sources: Located in factories, retail outlets, telecom towers, or vehicles.
Low Latency: Critical for applications such as autonomous driving, industrial automation, and AR/VR.
Bandwidth Optimization: Reduces unnecessary data transmission to central clouds.
Distributed Intelligence: Enables AI inference at the edge, keeping sensitive data on-site.
Distributed infrastructure complements edge computing by connecting multiple edge nodes, cloudlets, and central data centers into a cohesive, intelligent network. It balances workload dynamically between local and centralized resources.
