Enterprise Database Migration and Optimization to Amazon Redshift with Disaster Recovery

About project:

Client overview

The client, a large enterprise with complex data infrastructure, needed to migrate over 200 databases from various operating systems to Amazon Redshift to enhance scalability and performance. They required database consolidation, version upgrades, and a robust disaster recovery setup to support their growing data needs and ensure business continuity.

Tech Stack:

Amazon Redshift, AWS DMS, AIX, HP-UX, Linux, Redshift Spectrum, AWS Backup, Python.

Time to deliver project:

14 weeks

Problem

The client needed to migrate over 200 enterprise databases from various platforms (AIX, HP-UX, Linux) to Amazon Redshift. They also required a consolidation of databases, version upgrades, disaster recovery setup, and performance optimization to meet growing data demands.

Inspection

We reviewed the architecture of each database, identified compatibility issues with Redshift, and mapped the migration process. We also assessed legacy database versions that needed upgrades and established disaster recovery requirements.

Resolution

We successfully migrated the databases, upgraded them, and consolidated them on Amazon Redshift. A disaster recovery solution was implemented, and we optimized Redshift performance. This reduced query times by 35% and took 8 weeks.
