How a Leading Indian Insurance Provider Modernized a 20TB Workload and Eliminated Oracle Licensing Costs

A leading Indian insurance provider was dependent on a complex, 20TB Oracle database setup. This dependency caused high enterprise licensing costs and limited cloud-native scalability. Mydbops led the modernization to Amazon Aurora PostgreSQL using AWS DMS. By converting 2,000+ tables and rewriting hundreds of complex code objects, the client successfully achieved zero Oracle licensing costs and established a highly scalable database setup without disrupting daily insurance operations.

CRITICAL BARRIERS

Stuck with a Legacy Database?

Proprietary engines impose heavy operational boundaries. We convert legacy challenges into open architecture:

Crippling Licensing Costs

Avoid expensive Oracle support contracts, unpredictable yearly fees, and vendor audits that push unwanted structural upgrades.

Performance Bottlenecks

Tackle core systems struggling under high transaction loads, real-time reporting needs, and complex data structures.

Vendor Lock-In & Inflexibility

Break out of proprietary system locks that limit cloud deployments, complicate data flows, and increase support budgets.

ARCHITECTURAL PARADIGM SHIFT

Baseline Infrastructure Modernization

Transitioning legacy databases to PostgreSQL is more than code translation—it represents a leap from proprietary infrastructure ceilings to dynamic, cloud-optimized platform agility.

Vendor lock-in
Legacy stored procedures
Manual migration risk
Long downtime windows
