Case Study: Infosys achieves high-performance mission-critical OLTP and BI with Microsoft SQL Server 2012

Infosys - Customer Case Study

Infosys, a global consulting and technology firm, needed to upgrade its mission-critical OLTP and BI applications from SQL Server 2008 to improve performance, ensure high availability, and become cloud-ready. The complexity of their 45-terabyte environment, which served over 165,000 employees, required a meticulous upgrade strategy to achieve zero defects and minimal downtime. Microsoft Corporation provided support through its Microsoft Consulting Services and Microsoft Premier Support Services to address this challenge.

Microsoft implemented a solution by upgrading Infosys to SQL Server 2012, utilizing its new AlwaysOn high-availability feature. The vendor provided critical, year-long proactive support, including planning, design, extensive testing, and round-the-clock assistance during deployment. The results were significant: reporting latency dropped from two hours to near real-time, query performance improved by up to 72%, and execution duration was reduced by ten times. This provided Infosys with a highly available, high-performance, and cloud-ready platform.
