Edge computing reduces latency by processing or caching data closer to end users rather than in centralized servers.

To minimize response times, Amazon implemented distributed edge caching for frequently requested data. Popular queries such as weather updates were stored temporarily in regional servers. Edge nodes reduced round-trip latency to central data centers. The architecture complemented core cloud processing infrastructure. Localized caching optimized performance during peak usage. Engineering strategies balanced freshness of data with speed. Voice AI benefited from network topology refinement. Artificial intelligence answered more quickly through proximity.
