Fastly

A provider-neutral CDN configuration checklist covering origins, TLS, cache rules, cache keys, purges, observability, testing, and rollback.

Configure and validate Fastly VCL caching with explicit TTLs, a disciplined VCL cache key and TTL contract, correct Fastly pass behavior, origin-failure handling, shielding, staged activation, and practical rollback steps.

Set up and operate Fastly Next-Gen WAF policies safely with scoped signals and exclusions, request rules, simulation, logging, staged enforcement, and rollback.

A practical, verified guide to Fastly Compute deployment: reproducible WebAssembly edge packages, explicit service configuration, secret handling, local and staged testing, observability, and a tested Compute rollback path.

Configure Fastly origin shielding safely by choosing a shield near each origin, assigning it per backend, verifying cache-miss behavior, monitoring logs and headers, and retaining a rollback path.
