Learning case studies from the e-commerce industry

Big data analytics in the e-commerce industry helps businesses understand consumer purchase patterns, improve user experience, and increase revenue.

Case study 8 – migrating interactive analytical apps from Redshift to Postgres

An organization in the e-commerce space was using AWS Redshift as their data warehouse and Databricks as their ETL engine. The setup was deployed across different data centers in different regions on Amazon Web Services (AWS) and Google Cloud Platform (GCP). They were also running into performance bottlenecks and were incurring egress costs unnecessarily. The data was growing faster than the compute required to process that data. AWS Redshift was unable to independently scale storage and compute. Hence, the organization decided to migrate its data and analytics landscape to Azure.

AWS Redshift's data was migrated to Azure Database for PostgreSQL Hyperscale (Citus). Citus is an open source...
