Processing data closer to users at network edges rather than centralised data centres, reducing latency.
Edge computing runs code closer to the user (often at CDN locations) rather than only on a central server. This can reduce latency, improve reliability, and enable smarter caching, redirects, and security controls. For websites, it often powers things like A/B routing, bot mitigation, and personalised responses.
Edge is most valuable when it improves the user experience (speed, stability) or protects the site (security) without adding complexity to the core application.
