AI-Powered Metadata Catalog for FSx for ONTAP
An AWS Builders technical PoC demonstrates an AI-powered metadata catalog pattern that keeps raw unstructured files on FSx for ONTAP while storing queryable Iceberg metadata in S3 Tables. The verified AWS-native path (Athena + S3 Tables + Bedrock + OpenSearch + Lake Formation) completed an end-to-end demo in 42 seconds and cost $0.07 for the demo. The pattern uses Amazon Bedrock for AI classification and Titan embeddings for vector search (OpenSearch Serverless kNN). It substantially reduces discovery time (minutes–hours to <2 seconds at scale) and eliminates the need to bulk-copy raw files to S3, producing material projected cost savings versus full S3 copies. The article documents cross-platform compatibility tests (Databricks, Snowflake), governance via Lake Formation, known limitations, and operational considerations for production deployment.
A verified AWS-native PoC from a major cloud provider demonstrates a new metadata-first pattern (Iceberg on S3 Tables + Bedrock + OpenSearch) that can materially reduce discovery latency and storage cost while affecting cross-platform interoperability (Snowflake, Databricks) and governance practices—relevant to data infrastructure and analytics strategies across enterprise customers.

Key Takeaways & Evidence Grounding
- AWS-native PoC (Athena + S3 Tables + Bedrock + OpenSearch + Lake Formation) verified end-to-end in 42 seconds
- Pattern keeps raw files on FSx for ONTAP and writes only Iceberg metadata to S3 Tables (metadata-as-source-of-truth)
- File discovery improved from minutes–hours to under 2 seconds by querying Iceberg metadata (measured/projection up to 1M+ files)
- Demo cost was $0.07; projected monthly example (10TB, 100K files) ~ $114/month versus ~$230–256/month for an S3 copy
- Cross-platform findings: Snowflake via Glue REST with ACCESS_DELEGATION_MODE=VENDED_CREDENTIALS verified (2026-06-05); several Databricks Unity Catalog paths remain blocked or limited in tested setups

Serverless Pipeline: FSx for ONTAP Logs to 9 Observability Backends
An AWS Builders technical article describes a single serverless architecture that ships Amazon FSx for ONTAP audit logs to nine observability platforms (Datadog, New Relic, Splunk, Grafana Cloud, Elastic, Dynatrace, Sumo Logic, Honeycomb, and an OTel Collector path). The team validated CloudFormation templates across 12 articles and three event sources, documented vendor-specific batch limits and auth models, and measured a ~90% AWS cost reduction versus an EC2-based collector. Key operational patterns include a 5-minute EventBridge Scheduler poll (due to FSx S3 Access Point limitations), checkpoint-after-delivery, credential caching with reload-on-401, a reserved concurrency of 1, and KMS-encrypted DLQs. The post recommends starting with an OTLP/OTel Collector path for multi-vendor evaluation and pins tested OTel Collector Contrib version v0.152.0. Publication date: 2026-05-31.
Open-source Enterprise RAG Platform on AWS
An engineer published and open-sourced a production-ready Retrieval-Augmented Generation (RAG) blueprint called the Enterprise Refund AI Assistant that runs on a 100% serverless AWS architecture. The design decouples asynchronous document ingestion from synchronous inference: documents are chunked, embedded via Amazon Bedrock (Titan Text Embeddings V2), indexed in Amazon OpenSearch Serverless, and served through API Gateway + Lambda to Amazon Nova Lite for grounded responses. Infrastructure is provisioned with Terraform and deployed via GitHub Actions with OIDC; conversation history is kept in DynamoDB. The post includes implementation details (1,000-character chunk window with 200-character overlap), performance benchmarks (average end-to-end latency 1.15s; vector search ~120ms; Nova Lite ~850ms), and estimated operating costs (serverless idle compute $0; orchestration < $45/month at ~10,000 queries/day). The full implementation and walkthrough links are published as open source on GitHub with a YouTube demo.
Serverless FSx for ONTAP Logs to Datadog Integration
This technical guide describes a serverless pattern to deliver FSx for ONTAP audit logs into Datadog Log Explorer. The solution deploys a single CloudFormation stack that provisions a Lambda function, EventBridge Scheduler, DLQ (SQS), IAM roles, CloudWatch alarms and a dashboard. The Lambda lists objects from an FSx for ONTAP S3 Access Point, reads EVTX/XML audit files, normalizes events, batches them within Datadog Logs API v2 limits, and ships with exponential backoff and jitter. Checkpoint semantics ensure the pipeline is at-least-once (checkpoint advances only after all batches succeed). The post includes Datadog field mappings, operational validation steps, troubleshooting notes (eg. VPC / S3 AP timeouts, gzip issue on AP1), day‑2 replay/reset procedures, and a cost estimate (~$2/month without VPC, ~$30–50+/month with VPC/NAT for a typical small deployment).
