Overview
How a European Healthcare Leader Modernised Its IT Ecosystem with Event-Driven Integration
A European multinational corporation specialising in the Sales, Distribution, Installation, and Servicing of medical equipment was operating on a fragmented IT landscape. Its core business systems — Oracle Fusion, Salesforce, Oracle EBS, Oracle Service Cloud, and Oracle Field Service — operated across both cloud and on-premises environments with no unified integration layer. The result was slow data flows, manual intervention, and an inability to scale operations efficiently.
TGH designed and delivered a Boomi-powered, event-driven integration architecture — leveraging Solace as the messaging backbone — that connected all core systems in real time, eliminated manual processes, and built the scalable, high-availability platform the organisation needed to support future growth.
The event-driven integration platform TGH built on Boomi and Solace transformed how our systems communicate. We now have real-time data flow, zero-downtime operations, and the scalable foundation we needed to modernise our entire IT ecosystem across sales, distribution, and servicing.
Business Goals
Four Strategic Objectives Driving This Engagement
The engagement was anchored to four core business imperatives — spanning platform scalability, speed-to-market, customer experience, and operational visibility — all requiring a robust, unified integration foundation.
🏗️
Build a scalable, robust, and future-ready integration platform capable of supporting ongoing business growth
🚀
Achieve faster time to market through efficient integrations across all business systems and workflows
🤝
Improve customer support and shorten supplier payment cycles through automated, real-time data exchange
📊
Improve asset management via centralised data and process visibility across distribution and field service
The Challenge
Bridging Cloud & On-Premises Systems Without Compromising Availability
The client's technical environment presented three interconnected challenges that demanded careful architectural thinking. Each required a design decision that balanced real-time performance, operational resilience, and long-term maintainability — in a Healthcare context where system reliability is non-negotiable.
Integrating cloud and on-premises systems with diverse technologies — The client's environment spanned Oracle Fusion (cloud), Salesforce (cloud), Oracle EBS (on-premises), Oracle Service Cloud, and Oracle Field Service — each with different APIs, protocols, and data models requiring a unified integration strategy.
Event-driven architecture for real-time data flow and scalability — Traditional polling-based integrations couldn't meet the client's need for real-time responsiveness across systems. The architecture required event-driven messaging to ensure immediate data propagation without polling overhead — at enterprise scale.
High availability and zero downtime with seamless connectivity — As a Healthcare business serving patients and clinical customers, any system outage or data processing failure carries significant operational risk. The platform had to guarantee high availability, automated failover, and zero-downtime deployments across all integration paths.
Our Solution
A Boomi + Solace Event-Driven Integration Platform Built for Healthcare Scale
TGH used Boomi as the centralised integration platform for connecting all core business applications, and Solace as the event-driven messaging layer — enabling flexible, asynchronous, and highly resilient data flows across every system in the client's ecosystem.
High availability and zero downtime were achieved by deploying Boomi Molecule as the runtime engine — a clustered, multi-node runtime environment that ensures seamless operations even if individual nodes fail. All integrations were built using enterprise integration patterns, best practices, and Boomi's built-in components to ensure scalability, consistency, and long-term maintainability.
💡
Boomi Molecule's multi-node runtime cluster was the key to achieving zero-downtime operations — distributing integration processing across multiple runtime nodes behind a Load Balancer, so any single node failure is invisible to the business. Data continues flowing without interruption.
Implementation
Enterprise Integration Delivery Across Four Structured Phases
Phase 1
Discovery & Architecture Design
Phase 2
Platform Build & Event Design
Phase 3
Testing & HA Validation
Phase 4
Go-Live & Hypercare
01
Enterprise Architecture Design — Boomi + Solace Event-Driven Framework
TGH conducted a comprehensive assessment of the client's existing IT landscape — cataloguing all systems, APIs, data flows, and business processes. The output was a detailed integration blueprint defining the event-driven architecture: Boomi as the central orchestration engine, Solace as the messaging fabric, and Molecule as the high-availability runtime engine.
02
Boomi Molecule Cluster Deployment — Load Balancer & Multi-Node Runtime
An on-premises Boomi Molecule Runtime Cluster was deployed with multiple runtime nodes behind a Load Balancer — distributing integration processing to ensure zero-downtime operations. The cluster was configured to handle automatic failover, so business-critical integrations continue uninterrupted even if individual runtime nodes experience issues.
03
Solace Event-Driven Messaging Integration
Solace PubSub+ was integrated as the event-driven messaging layer — enabling asynchronous, pub-sub communication between cloud and on-premises systems. This decoupled architecture allows each system to publish and consume events independently, providing the scalability and flexibility needed for real-time data flows without tight coupling between endpoints.
04
Core Business System Integrations — Oracle, Salesforce & Field Service
TGH built and validated all core integration flows: Oracle Fusion ERP ↔ Salesforce CRM, Oracle EBS ↔ Oracle Service Cloud, and Oracle Field Service data flows — using enterprise integration patterns and Boomi's built-in components. All integrations were built with standardised error handling, logging, and retry logic for operational consistency.
05
Error Handling Framework & Reprocessing Engine
A standardised error handling and retry framework was implemented across all integration processes — automatically capturing failed executions, quarantining error records, triggering alerting, and enabling efficient reprocessing without manual intervention. This directly improved system reliability and reduced support burden for the IT operations team.
06
Production Go-Live, Monitoring & Continuous Optimisation
Production cutover was executed with zero downtime, leveraging the Molecule cluster's high-availability configuration. TGH deployed real-time integration monitoring with automated alerting, and conducted a hypercare period — validating all flows, optimising performance, and training the client's IT team on the Boomi platform for long-term self-sufficiency.
