// Scale
Caching & CDN Setup
Caching and CDN are the most cost-effective performance investments for most applications, serving content from memory or edge nodes eliminates round-trips to origin servers and databases that are orders of magnitude slower.
// Key benefits
What makes this service valuable
Multi-layer caching strategy
Application-level cache (Redis/Memcached), HTTP caching (Cache-Control headers), reverse proxy cache (Varnish/Nginx), and CDN edge cache, each layer reducing load on the next.
CDN configuration expertise
Cloudflare, CloudFront, Fastly, and BunnyCDN. We configure CDN rules, cache invalidation, geo-routing, and edge functions for maximum cache hit rates and minimum stale content.
Cache invalidation strategy
Cache invalidation is famously hard. We design cache invalidation strategies that keep content fresh without causing stale data problems or cache stampede on invalidation.
// Details
Serving content at the speed of memory
An uncached request to a database takes 50–200ms. A cache hit from Redis takes under 1ms. A CDN edge response from a user's nearest PoP takes 5–20ms. Caching is the highest-leverage performance investment for most applications.
We design a caching strategy appropriate for your application's data freshness requirements, not a one-size-fits-all approach that causes either stale content or cache misses.
// What this includes
- Redis or Memcached application cache setup
- HTTP Cache-Control and ETag headers
- CDN configuration and cache rules
- Cache invalidation strategy
- Database query result caching
- API response caching
- Cache hit rate monitoring

// In practice
How caching & cdn setup engagements run
Caching layers combine CloudFront or Cloudflare edge rules, Redis for session/object cache, and cache-control headers tuned per content type — HTML short TTL, static assets immutable hashes. Origin shield and stale-while-revalidate reduce thundering herds during traffic spikes. Edge hit ratio and origin bandwidth are baselined before tuning, with improvement tracked per asset class.

// FAQ
Common questions about caching & cdn setup
How do you prevent serving stale content after an update?+
Cache invalidation strategy is designed alongside the cache setup, either time-based TTL for acceptable staleness, event-driven invalidation for real-time freshness, or stale-while-revalidate for background updates without latency cost.
