TL;DR

This is Phase 10 of the FSx for ONTAP S3 Access Points serverless pattern library. Building on Phase 9 , Phase 10 delivers:

FPolicy event-driven integration : ONTAP FPolicy → ECS Fargate TCP server → SQS → EventBridge custom bus. The shared event-ingestion pipeline is verified end-to-end; UC-specific dispatch follows in Phase 11.

Multi-account StackSets : All 17 UC templates validated for StackSets compatibility (0 errors) + admin/execution role templates

UC-specific alarm profiles : BATCH / REALTIME / HIGH_VOLUME — three profiles with workload-appropriate thresholds

Cost optimization : Dynamic MaxConcurrency controller + business-hours scheduling (rate(1h) vs rate(6h))

E2E verification : NFSv3 ✅, NFSv4.0 ✅, NFSv4.1 ✅, SMB ✅, NFSv4.2 ❌ (unsupported by ONTAP FPolicy)

In short : Phase 9 completed the operational baseline. Phase 10 builds and verifies the shared event-ingestion pipeline that the pattern library has needed since Phase 1 — without waiting for AWS to ship native S3AP notifications.…
