From Legacy Infrastructure to Enterprise Cloud Using a Co-existence Framework
Transformation Overview
The Reserve Bank of India (RBI), the systemic backbone of India’s financial infrastructure with a balance sheet of ~USD 0.92 trillion , modernized its mission-critical operations by upgrading from Intellect Quantum (eKuber 1.0) to the next-generation eKuber 2.0. This transformation leveraged a carefully architected co-existence framework over 21 months to replace legacy monolithic systems with a highly composable, eMACH.ai-based cloud-native architecture.
