Legacy ESB to MuleSoft Migration

Modernized a critical legacy integration layer from Informatica ESB to Anypoint Platform, reducing cycle times by 3 weeks and saving $250K annually.

Context & Stakes

The existing Informatica ESB infrastructure was reaching end-of-life and had become a bottleneck for business innovation. Cycle times were measured in months, and maintenance costs were skyrocketing. The objective was to migrate the mission-critical integrations to MuleSoft while ensuring zero downtime for the existing production systems.

Architecture & Mandate

Technical Architecture Diagram Placeholder

Key responsibilities included: - Mapping legacy Informatica patterns to modern Mule 4 architectures. - Developing a migration factory model to accelerate payload transformations. - Implementing event-driven patterns using Solace for real-time sync. - Validating all migrations through automated test suites and DR drills.

Measurable Results

$250,000 Annual savings in licensing and compute
3 Weeks saved per release cycle
Reduced technical debt by 60%
Zero production downtime during migration

Post-Mortem: What I'd Do Differently

"If I could do it again, I would have pushed for a 'big bang' migration on the low-complexity services rather than a purely phased approach. We spent a lot of time managing the 'dual-run' sync between Informatica and MuleSoft for simple integrations that could have been ported and switched in a single weekend with minimal risk."
