Case Studies / Reducing Proprietary Footprint with AWS Redshift Migration

Reducing Proprietary Footprint with AWS Redshift Migration

Karsun Solutions cloud modernization experts enable the safe transition away from expensive legacy technologies. As an Amazon Web Services (AWS) Advanced Consulting Partner, we leverage the AWS catalog as a key component in these cloud solutions. Karsun Solutions’ Samir Bham describes a recent implementation for one of our public sector customers. In this AWS Redshift migration case study, he describes Karsun’s method to transition a customer away from a costly proprietary database.

Key Challenge

Reducing the Proprietary Database Footprint

One of Karsun's public sector customers desired to move out of commercial off-the-shelf (COTS) and legacy technologies. The customer's goal was to reduce its proprietary database technology footprint. The assets in concern were the enterprise data warehouse hosted in a columnar store database.


Modernizing with Redshift

After creating a script-based cluster instantiation and configuration, we launched the AWS Redshift cluster set.  This, along with S3 buckets and folders with appropriate privileges, was used as a replacement for the legacy data warehouse.  This allowed for further refinement based on customer security requirements. View the architecture for this solution below:

Successful Data Migration

Karsun Solutions completed a successful 100% data migration into Redshift of the in-scope data warehouse.  Downstream applications and data consumers could successfully query performance and access data access. Based on this migration out of the data warehouse, the customer obtained the ability to retire or reduce the footprint of legacy technologies.
