FedRAMP Moderate Boundary Built on AWS GovCloud
A technical case study describes how Stonebridge Tech Solutions architected a FedRAMP Moderate authorization boundary on AWS GovCloud for an AI SaaS vendor pursuing federal procurement. The engagement prioritized drawing a clear authorization boundary before writing infrastructure-as-code, implemented a four-account AWS GovCloud topology (production, staging, logging, shared services) with cross-account PrivateLink and IAM Identity Center federation, and served inference exclusively via AWS Bedrock under a GovCloud BAA. The team delivered a Terraform module library where each module includes a control narrative mapped to NIST 800-53 controls, enforcement policy gates (OPA + Sentinel), self-hosted GitHub Actions runners inside the boundary, centralized write-only logging with S3 Object Lock retention, and artifacts required for a 3PAO readiness review. The client passed the first-party 3PAO readiness review on schedule.
Practical, detailed engineering case study showing a repeatable FedRAMP Moderate boundary pattern on AWS GovCloud; valuable to teams pursuing federal authorization and cloud-compliance architecture but niche to public-sector/compliance contexts rather than broadly industry-shifting.

Key Takeaways & Evidence Grounding
- FedRAMP Moderate authorization boundary was implemented on AWS GovCloud for an AI SaaS vendor.
- Account topology used a four-account model: production, staging, centralized logging (write-only), and shared services (IdP / KMS).
- Inference endpoints were served exclusively via AWS Bedrock under the GovCloud BAA; a managed pgvector deployment hosted the RAG vector store inside the boundary.
- A Terraform module library shipped with control narrative files mapping resources to NIST 800-53; the SSP was generated from those narratives.
- The engagement passed a 3PAO readiness review on first-party assessment and met the customer's authorization timeline.

OpenAI Achieves FedRAMP 20x Moderate Authorization
OpenAI has obtained FedRAMP 20x Moderate authorization for ChatGPT Enterprise and its API Platform, enabling U.S. federal agencies to use OpenAI’s managed AI products under federal security, privacy, and governance requirements. The authorization leverages the GSA’s FedRAMP 20x process, which emphasizes cloud-native evidence, Key Security Indicators (KSI), automated validation, and ongoing operational visibility. Agencies can procure via Carahsoft, engage OpenAI directly, or evaluate other acquisition routes; OpenAI also says agencies can access powerful models (including GPT‑5.5) in the FedRAMP environment and will soon enable access to a Codex Cloud environment integrated with FedRAMP account management. OpenAI points agencies to its Trust Portal and the FedRAMP Marketplace for supporting evidence, scope details, and authorization materials.
Production-grade 3-tier AWS architecture with Terraform
A Dev.to author publishes a detailed walkthrough and full GitHub repo (vatul16/terratier) that provisions a production-minded, modular Terraform stack for a small Go/Node.js app on AWS. The design uses a four-tier VPC (public, frontend private, backend private, database isolated) across two Availability Zones, two ALBs (public and internal), RDS Postgres, Secrets Manager for credentials, and SSM alongside a bastion host. The post explains trade-offs: an internal ALB for stable backend scaling, Secrets Manager usage vs. environment variables, a single-NAT cost/availability option, robust user-data with retry loops, layered health checks, and observability endpoints. The author lists next steps (CI/CD, move to ECR, remote Terraform state) and includes the full Terraform source, module docs, and an architecture diagram on GitHub.
Blueprint: Host MCP Gateway Registry on AWS ECS
A technical blueprint explains how to host an MCP Gateway Registry for agentic AI systems on AWS using ECS Fargate and Terraform. The guide, based on the agentic-community/mcp-gateway-registry GitHub repo, describes a production-ready AWS architecture (Route 53, CloudFront, AWS WAF, ALB, ECS Fargate, Aurora PostgreSQL, DocumentDB, Secrets Manager, CloudWatch, ECR) and deployment stages including building/pushing ECR images, Terraform initialization, ACM certificate validation, full infrastructure apply, and post-deploy setup (Keycloak realms, DocumentDB initialization, registry indexes). It emphasises governance: the registry stores MCP server metadata (owners, scopes, approval state, health) and the gateway enforces authentication, authorization, routing, policy enforcement and detailed agent/tool observability and audit logging. The article recommends environment separation (dev/staging/prod), CI/CD with immutable image tags, and a scope-based access model to limit agent permissions.
