Is Cachee a CloudFront replacement?

No. CloudFront and Cachee solve different problems. CloudFront is a CDN that caches HTTP responses at edge locations. Cachee is an AI-powered application-layer cache that handles key-value data, sessions, API responses, and computed results at 1.5µs. Most teams use both — CloudFront for static content, Cachee for dynamic data.

How much faster is Cachee than CloudFront for application data?

Cachee serves cached data in 1.5µs from in-process L1 memory. CloudFront edge hits take 5-50ms depending on POP proximity. For application data like session tokens, API responses, and database query results, Cachee is 3,000-33,000× faster because the data never leaves the server.

Can CloudFront cache Redis keys or session data?

No. CloudFront only caches HTTP GET/HEAD responses. It cannot cache Redis key-value pairs, session state, database query results, or any application-layer data. Cachee speaks the full RESP protocol (133+ Redis commands) and caches any data type your application uses.

How much does CloudFront cost compared to Cachee?

CloudFront pricing is usage-based: $0.085 per 10,000 HTTPS requests plus data transfer fees ($0.085-0.170/GB). At 10M requests/month with 1TB transfer, CloudFront costs ~$385/month. Cachee’s Scale plan is $149/month with unlimited KV requests and AI optimization included.

Can I use Cachee with CloudFront?

Absolutely — they’re complementary. CloudFront handles HTTP content delivery at the edge (static assets, HTML pages, media). Cachee handles application-layer caching (Redis keys, sessions, API responses, computed results). Deploy Cachee as an L1 sidecar alongside your app, keep CloudFront in front for HTTP delivery.

Does CloudFront have CDC auto-invalidation?

No. CloudFront invalidation is path-based and takes 1-10 minutes to propagate across edge locations. It cannot watch database changes or invalidate specific cache keys automatically. Cachee's CDC auto-invalidation monitors your database WAL and invalidates affected cache keys in under 1ms — instantly, not minutes.

Does CloudFront support cache contracts?

No. CloudFront provides SLA guarantees at the service level (99.9% uptime) but has no per-key SLA enforcement, freshness contracts, or compliance audit trails for individual cached objects. Cachee's cache contracts let you define per-key SLAs that are SOC 2, FINRA, and HIPAA auditable.

Does CloudFront have a causal dependency graph?

No. CloudFront has no concept of key dependencies. Invalidation is path-based (e.g., /images/*) with no understanding of data relationships. Cachee's causal dependency graph lets you declare DEPENDS_ON relationships between cache keys, enabling automatic transitive invalidation when upstream data changes.

Different layers, not competitors: CloudFront is great for static assets — HTML, images, video. But it can't cache your Redis keys, session tokens, or API computations. Cachee sits at the application layer where CloudFront can't reach, cutting 99%+ of your cache misses before they ever hit the network.

Integration: Use Both Together

Complementary architecture: Use both: CloudFront for static content delivery, Cachee for application-layer KV caching. They complement each other. Cachee deploys as an L1 tier alongside your existing CloudFront distribution — no changes to your CDN config.
