Case Study: a US multinational telecommunications leader accelerates cloud migration with Persistent Systems and Microsoft Azure

US multinational Telco leader accelerates cloud migration with Microsoft Azure

The client, a US multinational telecommunications leader, sought to migrate and modernize thousands of complex, home-grown applications to Microsoft Azure to optimize costs and leverage new technology. The challenge was automating the entire migration process for these largely non-Microsoft applications to ensure a fast, seamless transition with minimal business disruption. Persistent Systems was engaged to help overcome these obstacles.

Persistent Systems devised a strategic four-stage migration process, utilizing infrastructure as code and fully automated CI/CD pipelines. The solution involved categorizing applications and executing a 'replace and not repair' strategy. This resulted in the client reducing operational costs by 80%, significantly cutting their physical data center footprint, and successfully migrating over 3,500 applications to Azure within two years.
