Partner Case Study | Infosys

Handling student and teacher data on a large scale is no easy feat. Upgrading a Student Information System (SIS), which manages daily attendance, enrolment, academic records, scheduling, and other student-related data, demands expert technical skills, a well-planned cloud migration strategy, and a robust framework for security and governance.

For over 25 years, Infosys has partnered with Microsoft and emerged as a frontrunner in secure modernisations and cloud transformations. The company holds various Solutions Partner designations in areas such as Data and AI, Digital and Application Innovation, Infrastructure, Modern Work, and Security. As one of the early adopters of GitHub Copilot and Microsoft 365 Copilot, Infosys has effectively managed enterprise-level transformations.

By utilising Infosys Cobalt, a collection of unique cloud transformation solutions, alongside Infosys Topaz, an AI-focused suite, the company has aided numerous large organisations in their quests for an AI-first and cloud-first strategy. With extensive knowledge of Microsoft Azure, GitHub Copilot, and Microsoft 365, Infosys has cultivated a reputation for delivering scalable, secure, and cost-efficient solutions.

This profound knowledge and collaborative background contributed to Infosys being named the 2025 Microsoft Partner of the Year for Azure – Secure Migration and Modernisation. Their established effectiveness was evident when they were entrusted to stabilize, modernise, and migrate the SIS for one of America’s largest school districts to Azure, resulting in one of the biggest SIS cloud deployments in any U.S. school district.

Every morning, a huge volume of data is generated by the 30,000 teachers taking attendance for over half a million students in Infosys’s client district. The legacy SIS previously in place was causing significant traffic spikes, revealing the limitations of their existing infrastructure.

“With over 1,400 schools and 500,000 students, you can picture the traffic intensity between 7:00 AM and 10:00 AM,” noted Sambit Mohanty, AVP Education Practice at Infosys.

Initially built on an outdated Microsoft .NET framework and hosted on-site, the SIS was meant to accommodate a vast and varied student population. However, scaling the system proved challenging, and it began to show its age. Teachers faced difficulties in recording attendance, while administrators experienced delays when trying to access student records. Every semester’s school openings—critical times for any district—posed potential major disruptions due to SIS instability.

“The school opening is the biggest event for a school district,” explained Mohanty. “Everything needs to run smoothly. Proper enrolment needs to occur, grades must be transferred, students need to be scheduled, and teachers should be able to take attendance seamlessly.”

Beyond its poor performance, the SIS was also expensive and ineffective. To tackle the chaos at the start of the year, the district assembled command centres with over 50 specialists from IT, network, and security teams, all trying to address issues in real-time. What they truly needed was a reliable partner to assist in stabilising the system and modernising it for lasting scalability and security.
