Case Study: Hudson’s Bay Company achieves full IT visibility and confident data-center shutdown with Device42

Hudson’s Bay Company - Customer Case Study

Hudson’s Bay Company (HBC), a holding company behind retail brands like Saks Fifth Avenue and Hudson’s Bay, faced a complex IT challenge: decades of growth, mergers and home‑grown applications left a mixed Windows, Linux and IBM AIX estate with little-to-no unified visibility. With plans to close its largest physical data center in Jackson, Mississippi and move workloads to multiple clouds (including IBM Cloud for AIX and Microsoft Azure), HBC needed accurate dependency mapping and a reliable source of truth to migrate without disrupting the business.

HBC adopted Device42 after a 14‑day proof of concept, deploying application dependency mapping and resource utilization to discover Windows, Linux and AIX systems, reveal cross‑platform dependencies and create topology maps and affinity groups. The single source of truth enabled right‑sizing, clearer conversations with app owners and confident migration planning; the Jackson shutdown began in spring 2021, Device42 access scaled to about 250 users, and HBC continues to use the platform to drive further migrations and hybrid IT management.
