Business Need

One of India’s leading Asset Management Companies (AMC) operated on a legacy, on-premise SQL Server data warehouse. As data volumes grew, the platform became costly to maintain, difficult to scale, and prone to bottlenecks, especially during critical End-of-Day (EOD) and Beginning-of-Day (BOD) reporting cycles.

The client needed a modern, cloud-native solution with mounting SLA violations and rising operational overhead. The transformation had to be completed within five months, with zero disruption to business operations.

Business Challenges

• Legacy SQL Server-based data warehouse with limited scalability and high maintenance costs.
• Repeated SLA breaches due to delayed EOD/BOD reporting.
• Complex stored procedures and data logic that hindered modernization.
• Aggressive five-month timeline for complete platform migration and optimization.
• Business continuity and SLA compliance are required during and after migration.

NuSummit’s Solution

NuSummit led the client’s end-to-end transition to a Snowflake-based data platform on AWS, delivering a modern, SLA-aligned, cloud-native architecture. Powered by GenAI, automation frameworks, and serverless design, the solution included:

AI-Powered Automation

• Built a GenAI-powered SQL code refactoring engine using AWS Bedrock to automate the conversion of ~1,000 SQL Server stored procedures.
• Automated DDL transformation for ~1,000 tables into Snowflake-compatible syntax in 10 days.

Cloud Migration at Scale

• Used NuSummit’s AWS Serverless Data Migration Framework to transfer ~5 TB of historical and incremental data.
• Ensured data integrity, validation, and a rollback-ready strategy to minimize risk.

Agile Execution and Optimization

• Applied agile delivery with iterative sprints to maintain business continuity.
• Refactored ETL and reporting logic for cloud-native performance.
• Tuned Snowflake for concurrent workloads and peak-hour elasticity.

Design Architecture
