The Monolith Trap vs. Composable Mesh
Legacy core ERPs excel at financial accounting and general ledgers. However, attempting to customize these systems for modern omnichannel order routing and real-time tracking leads to fragile codebases and crippling upgrade lock-in.
Architecture · Before
Monolithic Core Bottleneck
Heavy custom ABAP/PL-SQL logic, nightly batch ETL jobs, tightly coupled database tables, and single-point-of-failure scalability limits.
Architecture · After
Event-Driven Composable Mesh
Legacy ERP serves purely as financial System of Record, while lightweight DOM, WMS, and ATP microservices handle real-time execution.
