Platform-bundled AI decisioning over custom stream-processing for intra-session personalization

When intra-session latency personalization is needed (10 s – 5 min tier) but no backend stream-processing team is present, prefer platform-bundled AI decisioning (Layer 2) over building a custom streaming infrastructure. Building stream processing without dedicated staff is high-risk; platform-bundled decisioning absorbs the infrastructure layer at the cost of vendor lock-in.
