Key features
- APAC PoP coverage — Singapore, Tokyo, Seoul, Sydney, Mumbai, HK PoPs for APAC edge
- Sub-5ms cold start — no APAC cold start penalty vs Lambda/Cloud Run at APAC edge
- Workers KV — globally distributed APAC key-value store for edge config and sessions
- Durable Objects — APAC strongly-consistent coordination for WebSocket and rate limiting
- R2 object storage — S3-compatible APAC storage without egress fees from Workers
- D1 database — SQLite-based APAC serverless database for Workers
Best for
- APAC engineering teams adding edge authentication without origin latency — Workers JWT validation at Singapore/Tokyo PoPs eliminates APAC auth round-trips to origin
- APAC platform teams implementing geo-based routing and personalization — Workers access Cloudflare's APAC geolocation headers for country-specific APAC logic at the edge
- APAC teams using Cloudflare for CDN — Workers extend Cloudflare's APAC CDN with compute logic without adding APAC infrastructure complexity
Limitations to know
- ! V8 isolate runtime limits — Workers run in V8 isolates; APAC Node.js APIs (fs, crypto native modules) are not available; APAC teams must use Workers-specific APIs
- ! CPU time limits — Workers have 10ms CPU time limit (free) / 30s (paid); APAC compute-heavy tasks (AI inference, video processing) exceed these APAC limits and require different APAC compute
- ! Vendor lock-in — Cloudflare Workers uses proprietary APIs (KV, Durable Objects, R2); migrating APAC Workers logic to other APAC edge platforms requires API translation
About Cloudflare Workers
Cloudflare Workers is a serverless edge compute platform that runs JavaScript, TypeScript, and WebAssembly functions at Cloudflare's 300+ global Points of Presence (PoPs) — including Singapore, Tokyo, Seoul, Sydney, Mumbai, and Hong Kong — executing APAC requests within the Cloudflare network before they reach APAC origin servers, with typical cold starts under 5 milliseconds.
Cloudflare Workers' APAC deployment model — where APAC engineering teams deploy Worker scripts using Wrangler CLI (`wrangler deploy`) and Cloudflare distributes the Worker globally to all APAC PoPs automatically, with APAC requests routed to the nearest PoP — provides APAC engineering teams global APAC edge compute coverage without managing APAC regional infrastructure or Kubernetes deployments in each APAC jurisdiction.
Cloudflare Workers' storage ecosystem — where APAC Workers access KV (globally distributed key-value store for APAC configuration and session data), Durable Objects (strongly-consistent coordination for APAC WebSocket connections and rate limiting), R2 (S3-compatible APAC object storage without egress fees), and D1 (SQLite-based APAC serverless database accessible from Workers) — provides APAC stateful compute without external APAC data stores for common APAC use cases.
Cloudflare Workers' APAC use cases — where APAC platform teams deploy Workers for JWT authentication at the APAC edge (validating tokens before APAC requests reach origin), APAC geo-based routing (redirecting Singapore users to APAC Singapore-optimized content, Japanese users to Japan-compliant APAC pages), APAC A/B test assignment (persistent via KV), and APAC request transformation (normalizing APAC API headers before forwarding to APAC origin) — eliminates round-trips to APAC origin servers for logic that can execute entirely at the APAC edge.
