About Macy’s

Macy’s is a leading American department store chain renowned for its wide range of products, including apparel, accessories, cosmetics, home furnishings, and more. Established in 1858, Macy’s has become an iconic retail brand known for its flagship locations, annual Thanksgiving Day Parade, and commitment to providing quality products and exceptional customer service. With a strong presence both online and in physical stores, Macy’s continues to adapt to changing market trends and consumer needs, maintaining its status as a prominent player in the retail industry.


As consumer expectations and market dynamics rapidly changed, Macy’s faced several critical challenges that highlighted the need for platform modernization:

  1. Data Inconsistencies Across Databases: Macy’s operated with various databases, including DB2 on the mainframe and Oracle. This fragmented data environment led to inconsistencies and a lack of a unified data view, impacting decision-making and operational efficiency.
  2. High Maintenance and Licensing Costs: The legacy mainframe systems were not only expensive to maintain but also required substantial licensing fees. These costs were eating into Macy’s profitability, necessitating a move towards more cost-effective solutions.
  3. Speed to Market: The dispersion of data across multiple systems hindered Macy’s ability to develop and deploy applications swiftly. The time-consuming data consolidation processes delayed new initiatives, impacting Macy’s agility in responding to market trends.
  4. Inconsistent Customer Experiences: Discrepancies in inventory data between online and in-store channels resulted in inconsistent customer experiences. Out-of-stock situations and inventory surpluses were common, especially during peak shopping periods, frustrating customers and affecting sales.
  5. Complexity in Migrating Legacy Systems: The inability to sunset existing legacy systems added to the complexity of Macy’s operations. Transitioning to a modern cloud infrastructure was crucial to reduce dependency on outdated technologies and streamline processes.

Striim’s Solution

Striim’s comprehensive solution facilitated Macy’s migration to a modern, cloud-based infrastructure by leveraging Google Cloud Platform (GCP) services such as Cloud Spanner, Pub/Sub, and BigQuery. By replicating data from mainframe and Oracle databases to GCP, Striim created a unified data source, eliminating inconsistencies and providing a reliable foundation for decision-making and analytics. Real-time data synchronization ensured consistent customer experiences across online and in-store channels, preventing out-of-stock scenarios and enabling efficient inventory management. Striim’s architecture, featuring multiple Virtual Machines (VMs), ensured high availability and minimized downtime, enhancing disaster recovery capabilities. Additionally, the flexibility of Google Cloud allowed Macy’s to scale operations seamlessly during peak shopping periods like Black Friday and Cyber Monday, ensuring optimal performance and an exceptional user experience. By migrating data from costly mainframe systems to Google Cloud, Macy’s significantly reduced maintenance and licensing expenses, leading to substantial cost savings and improved profitability.
