What the integration estate actually does, before you decide what to do with it

Overview

Both investing further in MuleSoft and migrating off it require the same first step: knowing what is actually running, what it depends on, and where the reliability gaps are. Most estates cannot answer that from documentation.

Challenge

The integration team could not produce a reliable dependency map. Error handling varied by application — some had dead-letter handling, some retried indefinitely, some dropped failures silently. API-led layering had been adopted nominally, but system, process, and experience APIs called each other in patterns that did not match the intended architecture.

Environment

MuleSoft applications across CloudHub and on-premises runtimes, integrating clinical and administrative systems with HL7 and REST interfaces.

Approach

AceMQ inventoried applications, APIs, and connector usage from deployment metadata and application source, then mapped actual call paths against the intended API-led layering. Reliability was scored per application on error handling, idempotency, and observability, producing a ranked backlog.

Solution

• Built a complete inventory of applications, APIs, connectors, and runtime placement
• Mapped actual inter-API call paths and flagged deviations from the intended layering
• Scored each application on error handling, retry safety, idempotency, and observability
• Identified duplicated integration logic that should be consolidated into reusable APIs
• Flagged applications with silent failure modes as immediate remediation candidates
• Delivered a prioritized backlog usable for either platform investment or migration planning
