Context
As one of India's fastest-growing housing finance companies, the organization needed database infrastructure that could support rapid digital lending operations without the constraints of vendor lock-in. Their reliance on AWS RDS limited resilience, restricted operational control, and made their long-term multi-cloud strategy structurally impossible. They deployed Tessell's DBaaS platform to achieve unified database management across AWS and Azure, eliminating single-cloud dependency while reducing total cost of ownership.

About
The customer is one of India's leading housing finance companies, classified as an upper-layer NBFC by the Reserve Bank of India. They serve over 300,000 active customers through 200+ branches across India and rank among the largest housing finance companies in the country by Assets Under Management.
They provide comprehensive financing solutions including home loans, loans against property, and developer finance. Their digital-first approach enables rapid loan sanctions and disbursals. With AAA/Stable credit ratings and strong AUM growth, the company combines financial strength with operational agility to serve India's growing housing finance market.
The Challenge
A fast-growing NBFC with no room for database disruptions
The customer's digital-first lending operations depend on uninterrupted database availability. As a regulated upper-layer NBFC with AAA credit ratings, any database downtime directly impacts loan processing, customer transactions, and business continuity. Operating entirely on AWS RDS created a single point of dependency that leadership recognized needed to change.
1. Single-cloud dependency limited resilience and created vendor lock-in
- Their entire database infrastructure ran on AWS RDS, leaving them vulnerable to provider-level or regional disruptions.
- Multi-AZ configurations caused downtime during failovers and offered no protection against broader AWS outages.
- There was no viable path to multi-cloud operations.
2. Limited control over database operations
As a fully managed service, AWS RDS restricted their ability to customize configurations or integrate specialized security and observability tools required for a regulated financial institution.
3. Rising and unpredictable costs
RDS's layered pricing model - compute, storage, IOPS, backups, data transfer, and cross-AZ traffic made cost forecasting difficult as workloads scaled.
4. No unified platform for multi-cloud management
Managing databases across AWS and Azure without a unified control plane would create operational complexity and make consistent governance nearly impossible.
The Solution
The customer needed a multi-cloud DBaaS platform that could eliminate vendor lock-in while delivering enterprise-grade capabilities. Tessell delivered:
Unified multi-cloud database management
A single control plane across AWS and Azure, with centralized governance via native RBAC and subscription-level policies.
True cross-cloud redundancy and high availability

Multi-database service hosting on shared infrastructure with automated license tracking.
Operational autonomy for database teams
