Infosys modernizes giant Student Information System with Azure migration
Managing student and teacher data at scale is a high-stakes challenge. Modernizing a Student Information System (SIS) that tracks daily attendance, enrollment, academic records, scheduling, and other student data requires deep technical expertise, a structured approach to cloud migration, and a strong foundation in security and governance.
Infosys, a Microsoft partner for over 25 years, has long been a leader in these secure modernizations and cloud transformations. Infosys holds Solutions Partner designations spanning Data and AI, Digital and App Innovation, Infrastructure, Modern Work, and Security. As a leading adopter of GitHub Copilot and Microsoft 365 Copilot, Infosys has delivered enterprise-scale transformations.
Leveraging Infosys Cobalt, a proprietary set of solutions for cloud transformation, and Infosys Topaz, an AI-first suite of offerings, Infosys has been able to support multiple large enterprises in their AI-first, cloud-first transformation journeys. With deep expertise across Microsoft Azure, GitHub Copilot, and Microsoft 365, Infosys has built a reputation for delivering scalable, secure, and cost-effective solutions.
This experience and collaborative history are part of what made Infosys a 2025 Microsoft Partner of the Year for Azure – Secure Migration and Modernization. It’s also what made the company so successful when they were tapped to stabilize, modernize, and migrate the SIS for one of the largest districts in the country to Azure—creating one of the largest SIS cloud deployments for any US school district in the process.
Stabilizing and scaling a strained system
Each morning, teachers and students generate a massive amount of data for Infosys’s client, with 30,000 teachers taking attendance for more than half a million students. The district’s legacy SIS was creating intense traffic spikes and exposing the limits of their infrastructure.
“There were 1,400-plus schools, 500,000 students,” said Sambit Mohanty, AVP Education Practice at Infosys. “You can imagine the traffic between 7:00 AM and 10:00 AM.”
Originally built on a legacy Microsoft .NET framework and deployed on premises, the SIS was designed to support a vast and complex student population. But the system was not easy to scale, and it had begun to show its age, with disruptive performance issues that made it difficult for teachers to submit attendance and that caused delays when administrators tried to access student records. During school openings each semester—one of the most critical periods for any district—the instability of the SIS could present major issues.
“The school opening is the biggest event for a school district,” Mohanty explained. “Everything has to be fine. You should have proper enrollment, grades should be moved to the next level, students should be scheduled, and teachers should be able to take attendance.”
In addition to the suboptimal performance, the SIS was also costly and inefficient. To manage the start-of-the-year chaos, the district assembled war rooms with more than 50 experts across IT, network, and security teams trying to juggle and fix issues in real time. But they needed a partner who could support efforts to stabilize the system and modernize it for long-term scalability and security.
