TL;DR

This is Phase 5 of the FSx for ONTAP S3 Access Points serverless patterns collection. Building on the Phase 1 foundation , the 14 industry patterns from Phase 2 , the near-real-time + ML + observability stack from Phase 3 , and the production SageMaker + Multi-Account + Event-Driven from Phase 4 , Phase 5 delivers:

SageMaker Serverless Inference : 3rd routing option completing the Batch/Real-time/Serverless trifecta with cold start handling and automatic fallback

Cost Optimization Suite : Scheduled Scaling, CloudWatch Billing Alarms (3-tier), Auto-Stop Lambda for idle endpoint detection, and a comprehensive cross-phase cost guide

CI/CD Pipeline : GitHub Actions with OIDC authentication, 4-stage gating (cfn-lint → pytest → cfn-guard → Bandit), staging/production deployment with manual approval

Multi-Region Architecture : DynamoDB Global Tables for Task Token Store replication, CrossRegionClient failover, DR Tier 1/2/3 definitions with failover runbooks
