CDNs, Redis, Nginx, and load balancing.
Caching dynamic content at the edge isn't magic. It's about setting the right cache key and freshness rules—and knowing when to pull the plug.
A practical walkthrough of a caching and load balancing retrofit for a product catalog API, with specific numbers and blunt advice.
Cache-aside is the default for most apps, but we need to decide what to cache and for how long. Here's the framework we use, with concrete TTLs and va...
Walk through a realistic scenario where a bad load balancing algorithm choice turns a flash sale into a 503 storm, and learn how to pick the right one...
Most teams set a cache TTL and call it done. That's a mistake. Here's why stale-while-revalidate beats blind freshness windows—and how to use it.
Most caching failures aren't about picking the wrong tool—they're about treating a cache like a database. Here are the case studies that prove it.
Stop guessing TTLs. We walk through how to set max-age, use revalidation and stale-while-revalidate, and why a short-lived cache often beats a long on...
I've spent years tuning both caches and load balancers. Here's my honest take: fix your cache first, but only if you know where it sits. Let me walk y...
Cache hit rates can mislead. Here's what to watch for, how to set sane headers, and why you should treat your CDN like a load balancer.
Stop treating caching as a one-size-fits-all switch. We debunk the 'just set max-age' myth and show you how to layer caches, handle stale-while-revali...
Stop chasing cache hit rates. Learn why a 95% CDN hit ratio may be hiding a problem, and how a layered caching strategy with proper invalidation can a...
Stop treating your cache like a database. Learn why cache-aside wins, why Redis isn't a storage tier, and how to set TTLs that don't wreck your CDN hi...
Most teams bolt on load balancers to fix latency, but the real win is cache layering. A practical walkthrough for diagnosing cache misses, setting hea...
