DataOps Aurora L3 Construct

Deploys compliant Aurora Serverless v2 clusters with enterprise security controls. Currently supports Aurora PostgreSQL, with Aurora MySQL support planned.

Deployed Resources (per cluster)

Aurora Serverless v2 Cluster - Writer instance with configurable reader instances and automatic capacity scaling

KMS CMK (or project key) - Customer-managed encryption key shared across all clusters

VPC Security Group - Network access control with configurable ingress rules (or imported existing SG)

IAM Role - Enhanced Monitoring role for RDS performance insights at 60-second intervals

Secrets Manager Secret - Admin credentials with automatic password rotation

IAM Managed Policy - Per-cluster access policy granting rds-db:connect, rds:DescribeDBClusters, and Secrets Manager access

SSM Parameters - Cluster endpoints published for project integration (when projectName is set)

Related Modules

• DataOps Aurora App — App module that translates YAML config into this L3 construct's props
• DataOps Project — Provides shared KMS key and security groups via project integration

Security/Compliance

• KMS CMK encryption at rest enforced
• SSL-only connections enforced
• Non-default port required (port obfuscation)
• VPC-bound deployment (no public access)
• IAM database authentication enabled by default
• Enhanced Monitoring enabled (60-second intervals)
• CloudWatch Logs export enabled by default
• Automatic admin password rotation via Secrets Manager
• Backup retention enforced (default 7 days)
• Removal policy set to RETAIN (snapshot on delete)

Project Integration

When projectName is set, the construct uses the shared project KMS key for cluster encryption instead of creating a dedicated key per cluster. Cluster endpoints are published to SSM parameters under the project namespace.

Usage

import { DataopsAuroraL3Construct } from '@aws-mdaa/dataops-aurora-l3-construct';

new DataopsAuroraL3Construct(stack, 'aurora', {
