Field inspectors use a mobile app that must execute light logic with ultra-low latency near users, not only from a distant Region. Which associate-level design awareness is most appropriate?
Select an answer to reveal the explanation.
Short Explanation
When fingers on a phone can’t wait for a cross-country hop, push work toward the edge. CloudFront plus Lambda@Edge (and Wavelength for ultra-close device cases) shrinks that round trip for field apps. Mainframe-only, VPN-to-one-box, or killing the CDN keeps latency high.
Full Explanation
Edge and distributed compute patterns reduce latency when user or device distance dominates. CloudFront with Lambda@Edge can run lightweight logic closer to viewers; AWS Wavelength addresses ultra-low-latency needs adjacent to carrier networks. Associate-level designs should select edge options when Regional round trips violate field-app latency goals, rather than forcing all interaction through distant single-AZ or fully centralized paths.
