Fastly

Edge cloud platform; commonly cited in CDP architectures for Inter-page edge decisioning where the activation needs to happen within milliseconds of the request.

Fastly

What it is. Edge cloud platform offering programmable CDN, edge compute, and decisioning at the network edge.

Strengths in CDP context.

Sub-100ms edge response times for next-page personalization.
Programmable edge logic (Compute@Edge) — WebAssembly runtime with no cold starts; sub-microsecond execution; supports JavaScript, Rust, Go, and C++.
Key Value Store and Fanout integrations enable data access and real-time personalized messaging at the edge without central data center round-trips.
Used as one of the practical reference architectures for the Inter-page latency tier (source.real-time-clarity-md).

Analyst recognition (2026). Forrester Wave™: Edge Development Platforms, Q1 2026 — Leader (one of only two Leaders named). Perfect 5/5 scores across Innovation, Developer Experience, Performance, and Observability. Highest above-average customer feedback score among all evaluated vendors. Source: source.fastly-com.blog-fastly-ranked-leader-2026-forrester-wave-development-2026 (vendor-domain announcement; Forrester full report is paywalled; confidence 0.75). This is the first independent-analyst recognition for vendor.fastly in the KG; it supports use of Fastly in CDN-layer decisioning architecture recommendations but does not constitute CDP-specific analyst validation.

Where it fits. Organizations with web-first customer experiences requiring real-time personalization at the page-render boundary.

Where it is less suited. Organizations whose personalization needs are entirely server-side batch or daily cadence — edge compute adds operational complexity without benefit if no sub-second latency requirement exists. Mobile-app-only customers have no page-render boundary; APNs/FCM push or in-app messaging is the relevant delivery layer.

Alternative-to. AEP Edge Decisioning, Cloudflare Workers, AWS Lambda@Edge.

applies-to-latency-tierlatency-tier.inter-page— Fastly is reference architecture for inter-page edge decisioning
alternative-tovendor.adobe-experience-platform— AEP Edge Decisioning and Fastly Compute@Edge are both named reference architectures for the inter-page latency tier; they are substitutable for edge-personalization workloads.

alternative-tovendor.akamai— Peer edge-platform vendors for intra-page CDP decisioning. Fastly Compute@Edge executes rule-based decisioning at the CDN edge; Akamai Inference Cloud executes ML model inference at the CDN edge. Alternative selection depends on whether the decisioning logic is rule-based (Fastly is sufficient) or ML-model-based (Akamai Inference Cloud provides edge-AI capability).
