Scaling Healthcare Analytics for 50k+ Users

Client: Major Healthcare Provider | Platform: Tableau & Snowflake | Result: 99.99% Uptime Achieved

How we migrated a legacy reporting system to a scalable cloud architecture, reducing report load times by 60%.

The Challenge

A major healthcare provider was struggling with their on-premise Tableau environment. With over 50,000 users accessing critical patient care reports daily, the system was experiencing frequent downtimes and slow performance during peak hours. The legacy infrastructure simply couldn't keep up with the growing data volume.

Our Approach

Sleek Slack implemented a comprehensive migration strategy to move their analytics workload to a scalable Snowflake data warehouse with a clustered Tableau Server environment on AWS.

• Architecture Redesign: We designed a high-availability architecture with auto-scaling capabilities.
• Data Optimization: Migrated heavy extracts to live Snowflake connections, leveraging its compute power.
• Governance Framework: Implemented row-level security to ensure HIPAA compliance across all dashboards.

The Results

The migration was completed with zero data loss and minimal downtime. The new environment now supports:

• 99.99% Uptime: Ensuring critical data is always available for medical staff.
• 60% Faster Load Times: Reports that took minutes now load in seconds.
• Scalability: The system automatically adds resources during morning rounds when usage peaks.
