Edge Caching / CDN
Exact Definition
Edge Caching is the practice of storing static files, API JSON payloads, and pre-rendered HTML pages on servers located close to the user (at the 'edge' of the network) to reduce latency and speed up page load times.
Architectural Deep Dive
Instead of routing every page request back to a central server, CDNs cache pre-rendered pages at regional edge nodes. This reduces server load and decreases time-to-first-byte (TTFB) to under 30ms globally. We use on-demand revalidation to clear this cache instantly when database records are updated.
The ERPStack Approach
We configure global edge caching on Vercel's Edge Network for all ERPStack marketing hubs and static assets, achieving sub-second load times.
