- Embedding proprietary business rules directly into vendor proprietary scripting engines creates massive switching friction and technical debt.
- Clean architecture patterns (Hexagonal / Ports & Adapters) apply equally well to enterprise organizational infrastructure as to software microservices.
- Modernization should be incremental and strangle legacy bottlenecks rather than attempting high-risk big-bang overhauls.
The Vendor Lock-In Trap
Over years of operations, companies inevitably bake their most valuable proprietary logic—pricing algorithms, risk scoring, operational routing rules—directly into proprietary vendor platforms like Salesforce Apex, SAP ABAP, or custom ServiceNow scripts.
Over time, testing these rules becomes nearly impossible outside the vendor's walled garden. Release cycles slow to a crawl, license fees escalate annually, and migrating or adapting becomes an existential risk.
The Strangler Fig Strategy for Enterprise Systems
Rather than embarking on a multi-year, multi-million dollar rip-and-replace initiative that carries high failure rates, leading organizations employ the Strangler Fig approach.
New workflows and high-friction business logic are extracted into standalone, containerized micro-services with deterministic APIs. The legacy platform is gradually reduced to a passive system of record.
Over time, the enterprise regains full ownership over its intellectual property, dramatically lowers licensing overhead, and enables seamless future modernization.
