Case Study: Global Financial Services Provider achieves seamless Azure ExpressRoute migration and unified Microsoft Enterprise Edge visibility with NETSCOUT

Financial Leader Seamlessly Migrates to Azure With NETSCOUT

A global financial services leader with operations across the Americas, Europe, and APAC planned a large-scale migration to Microsoft Azure using private Azure ExpressRoute connections. As teams prepared the cutover, they encountered performance problems at a data center and lacked a single source of telemetry to determine whether the issue lay in NetOps, CloudOps, or with an ISP — a visibility gap that threatened the migration timeline and business service delivery.

The company deployed NETSCOUT’s nGeniusONE service assurance platform, InfiniStreamNG appliances, and Premium Support to instrument on‑premises router demarcations and the data center edge. Customized dashboards and real‑time TCP metrics quickly isolated retransmissions and timeouts, ruled out ExpressRoute/ISP causes, established baselines and alerts, and eliminated IT silos — enabling a seamless ExpressRoute connection, smoother Azure migration, and improved operational efficiency across regions.
