Svatantra Microfin is an NBFC microfinance lender serving 2.1 million customers through more than 800 rural branches across India. As the branch network expanded, its co-located data center was becoming a constraint. Provisioning fixed infrastructure could not keep pace with new branches or growing loan-processing volumes, while backend performance and security also needed attention. Flentas migrated Svatantra's core banking applications to AWS in under a month, with no interruption to branch operations. The migration also brought monthly infrastructure costs down by 40% and established a foundation for high availability, monitoring, security, and disaster recovery.
Svatantra was opening branches faster than its existing data center could provision infrastructure for them. With workloads projected to double within two years, the fixed-capacity model was becoming difficult to sustain.
Co-located infrastructure could not flex easily with branch expansion or seasonal spikes in loan activity.
Growing branch volumes were putting pressure on backend applications and infrastructure.
The existing environment had gaps in areas including perimeter protection and access controls that needed to be addressed as part of the migration.
Flentas' AWS-certified engineers structured the migration in stages, addressing architecture, storage, security, monitoring, and cutover as part of the same program.
Migrated Svatantra's business applications to AWS and implemented a highly available MSSQL Always-On database cluster.
Built the AWS environment using Amazon EC2, load balancers, and Amazon VPC, with UAT and production environments separated to support better governance.
Modernized storage with Amazon S3 and strengthened security and operations using AWS WAF, Systems Manager, and CloudTrail.
Established CloudWatch and SNS monitoring and managed the final cutover with AWS-certified engineers to minimize disruption to branch operations.
AWS Savings Plans, automation, and optimized resource utilization reduced monthly infrastructure spend.
Critical gaps, including S3 exposure and missing WAF protection, were addressed as part of the migration.
Continuous monitoring and incident support improved operational visibility and helped maintain uptime.
The AWS architecture was designed to support peak business days and scale with demand.
MSSQL clustering on AWS provided a foundation for recovery, with successful restore drills conducted across approximately 5TB of data.
The complete migration was finished in nearly one month, while Svatantra's 800+ branches continued operating.
“Really liked the whole experience right from planning, designing, implementation and delivery. The timeliness and professionalism spoke a lot about their maturity and experience around delivering Cloud based projects.”
