The Platform Services domain is the foundational pillar of the RIO platform. It owns every cross-cutting capability that all business domains depend on — the API gateway, shared infrastructure, analytics query layer, CRM data ingestion, audit trail, notifications, and the frontend application.

Services

API & Frontend

• Application Layer Service — the single API Gateway front door. Validates Cognito JWTs and proxies 41 routes over a VPC Link to all backend services.
• RIO Web App — the React + TypeScript frontend, the platform’s only human-facing consumer.

Infrastructure

• Platform Infrastructure — provisions the EventBridge bus, RDS PostgreSQL, Valkey cache, the ECS cluster, and per-service IAM credentials.
• Analytics Semantic Layer (Cube) — the governed query vocabulary over ClickHouse — 30 cubes with named measures and dimensions, plus an MCP server for AI assistants.

Data & Observability

• Data Ingestion Service — scheduled pipeline that extracts 29 tables from Actian CRM365 over JDBC, vaults PII, and loads S3, ClickHouse, and RDS.
• Audit Service — captures every rio-sourced domain event from EventBridge, normalizes it, stores it in DynamoDB, and archives an immutable copy to S3.
• Notification Service — EventBridge-triggered dispatcher that sends alerts through SES and Google Chat, and logs every delivery attempt to DynamoDB.
