How Shopify Handles Black Friday Traffic With Static Caching

Lucas and Luna break down how Shopify prepares its infrastructure for the biggest shopping day of the year. They focus on a specific technique: using edge static caching to absorb 90 percent of read requests before they hit the application layer. The episode walks through Shopify's architecture for serving storefront pages from CDN nodes, how they invalidate caches when a merchant updates a product, and what happens when the cache misses. Lucas explains the trade-offs between stale content and site reliability, and Luna asks about the blast radius of a cache stampede. They also touch on how Shopify's approach differs from a generic CDN setup. By the end, listeners understand one concrete pattern for scaling read-heavy traffic without burning server capacity. #Shopify #BlackFriday #StaticCaching #EdgeComputing #CDN #SiteReliability #CacheInvalidation #TrafficSurge #EcommerceInfrastructure #ReadHeavyWorkload #CacheStampede #WebPerformance #RubyOnRails #Fastly #Cloudflare #Business #Technology #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo
