TL;DR

This is Phase 6 of the FSx for ONTAP S3 Access Points serverless patterns collection. Building on Phase 1–5 , Phase 6 delivers:

Lambda SnapStart for Python 3.13 (6A): Cold start reduction typically from ~1–3s to sub-second (often ~100–500ms depending on init complexity and memory configuration), opt-in via single CloudFormation parameter

SAM CLI Local Testing (6A): Event templates, environment configs, and batch test scripts for all 14 use cases

CloudFormation Guard Hooks (6B): Server-side policy enforcement — deploy-time governance enforced at the CloudFormation service level

SageMaker Inference Components (6B): True scale-to-zero completing the 4-way inference routing (Batch / Serverless / Provisioned / Components)

All features remain opt-in via CloudFormation Conditions (default disabled, zero additional cost when not enabled).
