Global Enterprise Integration Fabric

A secure, event-driven integration backbone built on **Dell Boomi** and **Apigee**, orchestrating critical employee and financial data synchronization.

The Problem

Disparate HR and ERP ecosystems (SAP SuccessFactors, S/4HANA, Salesforce) across global subsidiaries resulted in data fragmentation and security risks.

Why Traditional Systems Failed

Point-to-point integrations create a fragile "spaghetti" architecture that is impossible to govern or scale as new SaaS vendors are added.

Technical Approach

Designed a Hub-and-Spoke architecture using Boomi for transformation logic and Apigee for security governance. Implemented reliable pub/sub patterns for asynchronous data propagation and X.509 certificate-based mutual auth for security.

High-Level Architecture Overview

Hub-and-Spoke Pattern: Source Systems → Boomi Atom (Transform) → Apigee (Secure) → Target Systems

Business Value

Reduced vendor onboarding time by 40% and ensured 100% data consistency across global HR registries.

Key Learnings

  • Stateless integration processes are key to horizontal scalability.
  • Centralized error handling (Dead Letter Queues) is mandatory for event-driven systems.
  • Governance at the API gateway layer prevents logic sprawl in the integration engine.
