About This Architecture

Secure closed-network AWS PoC environment integrating IAM Identity Center, ECS Fargate, Amazon EC2, and Amazon Bedrock within an isolated VPC (10.0.0.0/16) using VPC endpoints for zero-inbound-port access. Data flows from developers through IAM Identity Center to core processing via ECS Fargate and EC2, with S3 Gateway Endpoint enforcing strict bucket policies and Bedrock Guardrails protecting Claude 3.5 Sonnet model invocations against injection and PII exposure. Security and governance layers—CloudTrail, GuardDuty, Macie, AWS KMS, and AWS Budgets (1200/mo cap)—provide audit trails, threat detection, and cost controls across processing, input-source, and final-deliverables buckets with WORM Object Lock. This architecture demonstrates defense-in-depth for regulated AI workloads, eliminating inbound internet exposure while maintaining developer productivity and compliance auditability. Fork, customize, and adapt this diagram on Diagrams.so to match your organization's security posture and AI use cases.

How do I design a secure, closed-network AWS proof-of-concept environment that integrates Amazon Bedrock with zero-inbound-port access and compliance auditing?

This diagram shows a fully isolated AWS PoC using a private VPC (10.0.0.0/16), VPC endpoints for S3 and Bedrock access without internet exposure, IAM Identity Center for developer authentication, and Bedrock Guardrails to prevent injection attacks and mask PII. Security governance via CloudTrail, GuardDuty, Macie, and WORM S3 Object Lock ensures audit trails and regulatory compliance.
