AWS RDS for PostgreSQL

L1 — Multi-Modal Storage RDBMS Usage-based (instance + storage + IOPS) Commercial (managed Postgres)

Managed PostgreSQL on AWS with HIPAA BAA, SOC 2, FedRAMP Moderate/High (GovCloud), PCI DSS, ISO 27001. Automatic backups, Multi-AZ, encryption at rest with KMS, IAM database authentication. The BAA-signing path for healthcare AI agent stacks using Postgres.

AI Analysis

AWS RDS for PostgreSQL is AWS's traditional managed Postgres service — Commercial, full AWS attestation. Standard managed PG with automated backups, Multi-AZ, point-in-time recovery, encryption with KMS, IAM database authentication. The BAA-signing path for AWS-native Postgres workloads.

Trust Before Intelligence

RDS Postgres mirrors Aurora's trust analysis with traditional managed-DB ergonomics. Substrate trust = AWS; vendor trust = AWS attestations. Slightly less operational sophistication than Aurora (no separated compute/storage; failover is RDS-standard not sub-second), but simpler to reason about + lower cost for moderate workloads.

AI-Identified Strengths

  • + Standard managed Postgres
  • + Full AWS compliance
  • + Automated backups + point-in-time recovery
  • + Multi-AZ + read replicas
  • + PG extension support broader than Aurora's
  • + Lower cost than Aurora for moderate workloads
  • + Mature service with long track record

AI-Identified Limitations

  • - AWS-only
  • - No sub-second failover (use Aurora)
  • - Storage scaling has limits vs Aurora
  • - Premium pricing vs self-hosted
  • - Less mature than Aurora for high-scale workloads

Industry Fit

AI-Suggested Alternatives

AWS Aurora

Integration in 7-Layer Architecture

Role: L1 AWS managed Postgres.

Upstream: Application SQL.

Downstream: PG protocol + monitoring.

⚡ Trust Risks

high AWS lock-in for multi-cloud

Mitigation: Document AWS-only.

high Failover RTO assumed sub-second (Aurora-class)

Mitigation: Failover is minutes, not seconds. Use Aurora for sub-second.

Use Case Scenarios

strong AWS-native Postgres for compliance-attested workload

Standard fit.

moderate Production at extreme scale

Aurora fits better.

weak Multi-cloud Postgres

Use OSS or Crunchy Bridge.
