Edge Caching
Edge caching is a content delivery technique that stores copies of frequently accessed data (such as web pages, images, or API responses) on servers located geographically close to end-users, known as edge servers. This reduces latency and improves performance by serving content from nearby locations rather than from a central origin server. It is a core component of Content Delivery Networks (CDNs) and modern web architectures.
Developers should use edge caching when building applications that require fast global content delivery, such as e-commerce sites, media streaming platforms, or APIs serving international users. It is particularly valuable for reducing load times, handling traffic spikes, and decreasing bandwidth costs by offloading requests from origin servers. Implementing edge caching can significantly enhance user experience and application scalability.
