CloudFront offers two ways to run code at the Edge, effectively giving you a "global middleware" layer before traffic hits your .NET origin.

Imagine a "cache stampede." Your cache expires, and suddenly 1,000 users request the same heavy report from your .NET API simultaneously. Your database might crash. cloud front .net

Origin Shield sits between CloudFront and your origin. It ensures that even if 1,000 requests miss the edge cache, only one request goes to your .NET server. The other 999 wait for that one response to populate the cache. CloudFront offers two ways to run code at
