SSRS Reports Migration to Power BI Using Snowflake as aData Source

Executive Summary

Zelis Healthcare Inc., a leader in financial datasolutions for the U.S. healthcare industry, required a comprehensivemodernization of its analytics infrastructure. The initiative involvedtransitioning a legacy reporting ecosystem built on Microsoft SQL Server andSSRS over to a high-performance modern data stack combining the SnowflakeData Cloud with Power BI.

Challenges

Critical Report Latency: Legacy SSRS reports suffered from severe performance bottlenecks, causing long loading times that impacted daily operational business decisions.
On-Premise Infrastructure Slowness: The existing Microsoft SQL Server database structure was unable to process complex data sets efficiently, resulting in highly latent data fetches.
Maintenance & Version Controls: The engineering team faced massive consistency issues and operational overhead while trying to manage, update, and maintain fragmented legacy report definitions.

Key Solutions

Data Layer Cloud Migration: Successfully migrated all legacy MS SQL Server data into the high-performance Snowflake Data Cloud architecture to unlock modern, scalable storage and compute.
Backend Transformation Optimization: Converted and re-optimized complex SSRS stored procedures and embedded queries into native Snowflake SQL to maximize compute efficiency.
Power BI Cloud Deployment: Reconfigured and migrated traditional static SSRS layouts into the Power BI Workspace using Power BI Report Builder for a seamless cloud visualization experience.
Feature Enrichment: Upgraded and enhanced the dashboards during the migration process, integrating modern UI/UX design elements based on updated stakeholder requirements.

Business Benefits

Scalable & High-Efficiency Reporting: Delivered a highly consistent, economical, and rapid reporting solution tailored to support massive numbers of concurrent end-users.
Streamlined Database Management: Leveraged Snowflake’s managed cloud infrastructure to reduce maintenance overhead and drastically simplify database operations.
Superior Visualization & Insights: Provided end-users with interactive, modernized dashboards in Power BI, enabling faster, self-service data exploration and improved financial decision-making.
