Case Study
Customer has embarked on a journey to modernize and transform IT Landscape to improve access to care and provide premium services at a lower cost and faster time to market. Azure transformation was made possible in a record time of 14 months.
Infosys and Microsoft partnered together to bring the might of both the organizations in this transformation journey. Infosys assumed the end to end ownership for Azure platform hosting, transformation and Integration/ maintenance.
Key Challenges
- EOL technologies and aged Infrastructure posed challenges in terms of timelines for transformation thus making it very aggressive
- Legacy applications/ products with little or no documentation made it harder to discover and assess the landscape for transformation
- Technology modernization with multiple vendors and service providers added additional complexity to manage the coordination and yet achieve the objective in such aggressive timelines
