Practice
The client’s integration platform leaned heavily on legacy BizTalk services that had grown organically over the years. The result was duplicated logic, tightly coupled integrations, and mounting complexity in managing and scaling services. With no clear integration strategy, it was hard to innovate or onboard new services efficiently. They needed a strategic way to rationalise the estate and reduce technical debt without breaking business continuity.
We ran a structured ESB rationalisation and decomposition programme aimed at simplifying the integration services and improving architectural alignment. Workshops mapped out the integration landscape and surfaced opportunities to decouple and reuse. We consolidated the redundant services and standardised integration patterns for consistency across the platform. To guide the move off legacy services, we introduced a phased migration roadmap towards a more scalable, maintainable architecture, supported by stronger DevOps practices.
The integration landscape is leaner and easier to manage, with less duplication and better service reuse. The client can scale its integration services more efficiently and onboard new capabilities with less complexity. The structured approach also brought down technical debt and improved the long-term maintainability of the platform.
