Case Study: Americas Styrenics achieves a 12‑week, zero‑downtime migration of 40 interfaces to cloud integration with SAP HANA

How Can Cloud-Based Integration Simplify Business Process Orchestration with External Parties

Americas Styrenics LLC (AmSty), a styrenics manufacturer operating seven plants across the U.S. and Latin America, needed to modernize how it exchanges messages with third-party systems and partners. The company’s challenge was to migrate 40 existing interfaces from on‑premise SAP Process Integration to a cloud-based solution quickly, securely, and without disrupting production — while future‑proofing integration for an upcoming move to SAP S/4HANA.

AmSty implemented SAP Integration Suite on SAP Business Technology Platform with support from partner Int4, using Cloud Integration, Identity Authentication/Provisioning, SAP Alert Notification (integrated with ServiceNow), and Int4’s automated IFTT testing to validate migrated content. The hybrid cloud approach and a single point of entry for dynamic routing enabled rapid deployment and easier maintenance: 40 interfaces were migrated in 12 weeks with zero post‑go‑live incidents, 24x7 monitoring via ServiceNow, and a 70% reduction in testing time.
