You need to know whether model-X is worth deploying for your real workload. The benchmarks suggest yes, but benchmarks are static and your workload is not. The standard answer — build an eval harness — runs into two structural problems: harnesses are expensive to build well, and they tend to over-fit to the inputs you remembered to include in the corpus, missing the real production failure modes you discover only later.

CDN and Edge Computing Patterns#

A CDN (Content Delivery Network) caches content at edge locations close to users, reducing latency and offloading traffic from origin servers. Edge computing extends this by running custom code at those edge locations, enabling request transformation, authentication, A/B testing, and dynamic content generation without round-tripping to an origin server.

CDN Cache Fundamentals#

Cache-Control Headers#

The origin server controls CDN caching behavior through HTTP headers. Getting these right is the single most impactful CDN optimization.
