Physical distance dictates network round-trip time (RTT); a user in Tokyo accessing an origin server hosted in Frankfurt will experience inevitable transport delays governed by the speed of light through fiber optics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Content Delivery Networks (CDNs) solve this by distributing cached static assets and dynamic content closer to the end user across globally dispersed Points of Presence (PoPs). Selecting a CDN requires evaluating edge compute capabilities, cache invalidation speed, security integrations, and traffic pricing structures. This guide examines leading content delivery networks, analyzing their architectural models, performance trade-offs, and enterprise integration patterns.<\/p>\n\n\n\n<div id=\"ez-toc-container\"
