Case Study: SSAB achieves $2.9M in five-year savings with Ensono’s Azure mainframe modernization

SSAB saves $2.9M over 5 years with Ensono

SSAB, a global leader in advanced steels, faced challenges with costly and hard-to-maintain mainframe infrastructure relying on COBOL and IDMS. To eliminate this reliance, reduce costs, and improve scalability, they partnered with Ensono for a mainframe modernization and migration to the Microsoft Azure cloud.

Ensono designed and executed a solution that transformed SSAB's legacy systems by converting COBOL to C# .NET, migrating IDMS databases to SQL Server, and implementing an Azure Landing Zone. This 14-month program resulted in a $2.9 million net savings over five years, including a one-time cost avoidance and annual operational savings, while providing a future-ready, scalable cloud infrastructure.
