cloudflare

Edge deployment runs serverless functions globally on Cloudflare Workers, executing in V8 isolates with millisecond cold starts and automatic scaling. Deploy via Wrangler CLI with JavaScript, TypeScript, Python, or Rust/WASM for immediate global availability without regional selection.

Yes, full-stack edge applications combine Workers for compute, D1 for databases, R2 for object storage, KV for key-value data, and Pages for static hosting. Support includes Durable Objects for real-time state, Workers AI for inference, and multiple handler types (fetch, scheduled, queue, email, alarm).

KV, D1, and R2 integrate natively with Workers through bindings configured in wrangler.toml. KV provides millisecond access for caching and state; D1 handles relational data; R2 stores objects. All scale automatically and charge per-request with no minimum.

Pages hosts static sites globally and supports edge functions for dynamic logic. Deploy repositories directly via git integration or upload builds; add serverless functions using the /functions directory. Combine with Workers, KV, and D1 for full-featured applications.

Yes, Workers support multiple handler types: scheduled triggers run tasks on intervals, queue handlers process background jobs, email handlers parse incoming messages, tail handlers aggregate logs, and fetch handlers respond to HTTP requests. Configure all via Wrangler.

Edge functions have millisecond cold starts and automatic scaling but run in resource-constrained V8 isolates with request timeouts. Heavy computation, long-running processes, and large memory operations are unsuitable; use traditional serverless or dedicated servers for those workloads.
