Why Database Caching Layer Design Prevents Costly Failures

Database caching can save millions of dollars in compute costs—or cause catastrophic failures if designed poorly. Lucas and Luna dive into the infamous 2020 Fastly CDN outage, where a single caching misconfiguration took down major websites for an hour, and contrast it with the layered caching strategies used by companies like Cloudflare and Netflix. They explain the difference between write-through, write-around, and write-back caches, and why cache invalidation is one of the hardest problems in engineering. Tune in to learn how a well-designed caching layer can reduce database load by 80% without breaking your application. #DatabaseCaching #CacheInvalidation #FastlyOutage #WriteThroughCache #WriteBackCache #WriteAroundCache #LayeredCaching #Cloudflare #Netflix #CDN #DatabasePerformance #TechPodcast #DatabaseTech #FexingoBusiness #BusinessPodcast #SoftwareEngineering #DataStorage #CacheDesign Keep every episode free: buymeacoffee.com/fexingo
