Cloud Migration of Legacy Applications: Flentas for Svatantra

Client Profile

Svatantra Microfin (Svatantra) is a next-gen microfinance entity offering differential banking solutions. Since receiving a license from the Reserve Bank of India in 2013, Svatantra has provided financial and non-financial solutions to encourage entrepreneurship in rural areas, primarily amongst women. Svatantra constantly leverages technological innovation to bank the unbanked. By December 2022, Svatantra has proliferated with 800+ branches across 19 states having around 2.1 million active customers supported by 6500+ employees.

Key Requirement

In early 2021, Svatantra was looking for a technology partner to help them migrate their existing infrastructure to the Cloud. Svatantra had plans to scale its overall operations for the next few years. It included setting up numerous branches across rural India for better broad reach. It also meant that their workloads would double from existing ones in the next two years, significantly impacting on the existing customer base. The overall traffic increase on the backend applications and infrastructure needed to scale as per business demand.

Major Challenges

The IT infrastructure that Svatantra was using came with multiple challenges, as listed below:

On-demand scale to meet business growth
Performance issues related to infrastructure
Streamlined Infrastructure operations
Overall Security Posture

Solution

Svatantra aimed to move their Business applications (All-in) to AWS Cloud for efficiency, scalability, better performance, and security. To do so, Flentas' Cloud Migration team helped successfully migrate and set-up their entire infrastructure on AWS Cloud for their mission-critical applications with the setup of highly available respective Databases.

Look at the below points that elaborate briefly on how we helped design the roadmap, and plan and execute the migration plan on AWS Cloud.

Setup their Applications on AWS using the below services:
- AWS EC2 – To run the web services consumed by the Mobile Application.
- Load-Balancer – To load balance on multiple EC2 Instances and manage scale.
- MSSQL Cluster – Set up MSSQL always on high availability cluster in AWS and migrate on-prem data.
- Amazon VPC – To segregate the network between multiple environments.
Modernizing the applications to leverage object storage services by using fully managed AWS services like S3.
Our team of AWS-certified engineers assisted with planning the cutover for Svatantra application, helping them migrate their workload from their co-location infra to AWS.
Flentas also helped set up a basic monitoring system to alert the critical thresholds and Identify workload patterns.

AWS Services used:

Amazon EC2 – Compute workloads Amazon VPC – Isolated UAT and production environments ALB & NLB – Managed application traffic Amazon S3 – Secure object storage AWS WAF – Web security and geo restrictions AWS Systems Manager (SSM) – Automated patching Amazon EventBridge – Scheduled EC2 start/stop AWS CloudTrail – Audit logging AWS Savings Plans – Compute cost optimization Amazon CloudWatch & SNS – Monitoring and alerts

Business Impact

40% Cost Savings Achieved through automation, AWS Savings Plans, and optimized infrastructure utilization.

Enhanced Security Posture By closing all critical gaps (e.g., S3 exposure, missing WAF) and establishing best practices for secure workloads.

24/7 Managed Services & Improved Uptime Continuous monitoring, rapid incident resolution, and proactive optimization.

High Availability & Scalability An AWS-native architecture that supports on-demand scaling during peak business days.

Disaster Recovery Readiness We set up MSSQL clusters on AWS and performing successful restore drills for ~5TB of data.

Reduced Cutover Time Thanks to agile response and streamlined migration execution. The full migration was completed in nearly one month, enabling Svatantra to realize benefits faster.

Conclusion

The project not only delivered measurable business and technical outcomes but also provided valuable insights for future cloud transformation journeys:

Early adoption of AWS-native automation tools accelerates maturity and speeds up innovation. Security best best practices from Day 1 ensure compliance, protect critical data, and reduce risk. Segmenting workloads (UAT/Prod) improves scalability, governance, and operational control. Cost efficiency and operational excellence go hand-in-hand when the right cloud-native architecture is in place.

By combining a robust AWS architecture, strong security posture, and proactive managed services, Flentas enabled the client to achieve both immediate impact and build a future-ready foundation for continuous growth.
