Industrial Manufacturing ERP Modernization & Decoupled Architecture

Executive Mandate & Operating Scope

A multi-facility confectionery and packaged food manufacturer operating continuous, 24/7 manufacturing lines was constrained by a monolithic, client-server ERP system installed in 2011. As operations expanded to six production facilities, ten regional distribution hubs, and automated packaging machinery, the central transactional database suffered severe lock contention during peak operational shifts.

Whenever warehouse personnel executed high-frequency batch inventory audits, or the finance department generated month-end general ledger reconciliations, database lock escalations degraded transaction processing times for manufacturing plant floor barcode scanners, halting packaging lines. Furthermore, applying software patches or upgrading business logic required taking the entire monolithic ERP offline, threatening millions in lost product throughput.

Executive Role: Anant Mishra served as Principal Enterprise Systems Architect and Executive Technical Advisor, authoring the Strangler Fig migration roadmap, defining domain bounded contexts, and directing zero-downtime database replication.

The Architecture: Strangler Fig Modernization & Polyglot Persistence

To modernize the core enterprise software without risking a catastrophic factory stoppage, we engineered an incremental Strangler Fig architecture over a 14-month phased execution window:

Step-by-Step Modernization Cadence

1. Continuous Change Data Capture (CDC): Deployed Debezium connectors against the legacy database transaction logs, streaming table mutations into Apache Kafka topics with sub-second latency.
2. Domain Service Extraction: Extracted business domains into isolated, containerized Go microservices. The first domain isolated was Supplier Procurement, followed by Batch BOM (Bill of Materials) calculations, Finished Goods Logistics, and finally Financial Accounting.
3. Polyglot Persistence Deployment: Machine telemetry and floor tracking events were routed to write-optimized, append-only storage. Transactional state was moved to PostgreSQL clusters, while high-frequency recipe parameters were stored in Redis.
4. Continuous Dual-Write Reconciliation: For each domain cutover, automated reconciliation daemons evaluated data parity between legacy tables and modernized microservices every 15 minutes for 60 consecutive days prior to transferring write authority.
