Migration from IIB to MuleSoft
A dynamic retail customer was reliant on IBM Integration Bus, exporting services as SOAP. However, their mobile channels required lean, fast REST APIs to support modern business needs—prompting the shift to MuleSoft led by Yell Technology.
How Yell Technology helped a retail client transition from IBM Integration Bus (IIB) to lightweight, RESTful MuleSoft APIs for mobile-first services.
Challenges
- SOAP-heavy APIs: All services were SOAP-based, adding latency from verbose XML payloads and complex message structures.
- Mobile performance bottleneck: Mobile apps demanded lightweight, low-bandwidth REST endpoints—SOAP was too heavy.
- Future readiness at stake: The legacy IIB setup hindered scalability, agility, and faster delivery of digital services.
Solution
Yell Technology implemented a modern API-led migration using MuleSoft's Anypoint Platform:
- Full API migration Lift-and-shift of all IIB services into MuleSoft, transforming them into RESTful APIs for universal, lightweight access.
- Performance-centric API design Focused on reducing message size and enhancing speed—MuleSoft REST APIs replaced bulky SOAP services with leaner, efficient alternatives.
- Mobile-first access model Ensured APIs were globally accessible and optimized for mobile consumption, catering to modern user expectations.
Why Yell Technology’s Approach Worked
- API-led architecture Decoupled systems into reusable REST APIs, enabling better maintenance and faster feature delivery.
- Performance boost through simplification Migrated from XML-heavy SOAP to compact JSON REST—reducing payload size, improving parsing speed and network usage.
- Scalable, future-proof foundation MuleSoft’s platform supports additional integrations—such as with e-commerce, IoT, analytics, or third-party services—without large overhead.
Results
- Streamlined data flow: Achieved fast, REST-based access tailored for mobile and web apps.
- Improved user experience: Reduced latency and bandwidth usage with smaller payloads.
- Operational efficiency: Simplified maintenance and debugging by switching to REST architecture.
- Scalable and strategic: Built a flexible, reusable API foundation ready for future expansions.
Conclusion
Yell Technology successfully helped the retail client transition from legacy SOAP-based IIB to a modern RESTful architecture using MuleSoft—ensuring better mobile performance, quicker API delivery, and a future-ready integration ecosystem.
