Fastly

Configure and validate Fastly caching with VCL, explicit TTLs, safe cache keys, pass behavior, 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.

Deploy Fastly Compute with reproducible WebAssembly packages, explicit service configuration, secret handling, local testing, observability, staged activation, and a tested 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.
