Custom cloud migration provided scalability and improved performance

A multinational company wanted to benefit from using data warehouse services, advanced analytics, data mining, and reporting, by migrating from an on-premise Oracle-based platform into a scalable cloud data warehouse solution. Azure Synapse was chosen as a target platform, with supporting functions in Azure SQL Managed instance, data ETL with Azure Data Factory, reports in Tableau and PowerBI, and supporting UI and administration applications and APIs migrated into Azure Web Apps.

Custom cloud migration provided scalability and improved performance

The Challenge

The solution to be migrated had two terabytes-sized Oracle databases. Advanced analytics queries were in many cases timing out and underlying infrastructure had to be optimized for OLAP rather than OLTP. 

How It Was Solved

Azure Synapse platform was used as a data warehouse solution for OLAP. Oracle data was moved using Azure Data Factory workbooks. All OLTP-specific workloads were migrated to Azure SQL Managed Instance.

The Results

The final solution provided unparalleled scalability and improved performance running advanced queries using MPP capabilities of Azure Synapse. The performance of OLTP operations was greatly improved by using SQL Managed Instance capabilities. Data Warehouse and Operational Database were tightly integrated and synchronized using ETL capabilities of Azure Data Factory.
