Key Highlights
- OptiSol partnered with a leading FinTech provider to modernize their two-decade-old monolithic core platform through a microservices-driven architecture using the iBEAM framework.
- The legacy system faced frequent downtimes, scalability challenges, and growing maintenance costs that impacted customer experience and compliance.
- OptiSol executed a phased migration strategy, enabling uninterrupted business operations while refactoring critical modules into independent, reusable microservices.
- The project was completed in only 8 weeks, significantly reducing technical debt and empowering the client with a scalable, cloud-ready platform for future innovation.
Problem Statement
01
Outdated Technology: The core platform relied on outdated technologies developed over 20 years ago, which prevented smooth integration with modern APIs, new digital channels, and essential third-party services required for daily financial operations.
02
Performance Bottlenecks: Due to the monolithic design, high transaction volumes regularly caused system slowdowns and unexpected downtime. This led to frustrated customers, damaged trust, and a weakened reputation in a competitive FinTech market.
03
Rising Maintenance Costs: Maintaining and updating the legacy system required extensive manual intervention from IT teams. Over time, this increased operational expenses and diverted resources away from more strategic and revenue-generating initiatives.
04
Limited Agility: Developing new features or incorporating regulatory updates often demanded long development cycles. These changes also carried a high risk of causing unintended disruptions to critical workflows and business processes.


Solution Overview
01
Architecture Assessment: OptiSol used iBEAM to conduct a detailed evaluation of the legacy system’s architecture. This process mapped all business-critical modules, technical dependencies, and hidden complexities that needed to be addressed during migration.
02
Migration Roadmap: A structured migration plan was developed to prioritize the most important and high-impact modules. These modules were decoupled into independent microservices in a phased manner, ensuring operations continued without interruptions.
03
Hybrid Approach: The team combined automated extraction of business logic with manual refinement and optimization. This hybrid model helped preserve data integrity, meet compliance standards, and reduce the likelihood of errors during migration.
04
Cloud Deployment: All newly created microservices were containerized and deployed on a scalable, cloud-native infrastructure. This approach supported better performance, future scalability, and seamless integration with the client’s broader digital ecosystem.
05
Incremental Rollouts: Continuous testing and step-by-step rollouts were conducted for each microservice. This ensured smooth transitions, minimized disruptions for end-users, and verified that all critical functions performed as expected.
Business Impact
About The Project
This success story highlights how OptiSol partnered with a prominent FinTech company to modernize its core banking and transaction platform, which had been in use for over 20 years. The legacy monolithic system had become increasingly difficult to maintain and scale, resulting in high operational costs and performance bottlenecks during peak usage periods.
Using the iBEAM framework, OptiSol conducted a structured assessment of the platform and implemented a phased migration strategy. Business-critical modules were refactored into containerized microservices, enabling the client to achieve higher scalability, improved reliability, and faster development cycles. The collaborative approach ensured that the migration was completed within 8 weeks without disrupting ongoing operations, setting the stage for accelerated innovation and sustainable growth.
FAQs:
How does iBEAM handle the extraction and migration of business logic from a legacy system?
iBEAM uses automated analysis to map existing workflows, dependencies, and logic components, then extracts them into modular structures. Manual validation and optimization ensure the migrated microservices accurately replicate the original business functions without disruption.
What makes iBEAM different from other migration tools?
Unlike traditional tools, iBEAM combines automation with manual refinement, enabling precise conversion of complex logic while minimizing errors. Its structured methodology and phased rollout approach reduce risks and support faster, controlled migrations.
Are these improvements sustainable over time?
Yes. The modular microservices architecture enables ongoing scalability and performance optimization. Continuous monitoring, automated scaling, and easier updates help maintain efficiency and cost savings long after the initial migration is completed.
Can this approach be used for smaller companies or only large enterprises?
iBEAM’s framework is adaptable for organizations of any size. Smaller companies benefit from the same automation and phased execution, allowing them to modernize legacy systems cost-effectively without requiring large in-house teams.
How does microservices architecture enable faster innovation?
Microservices decouple features into independent units, allowing teams to develop, test, and deploy changes separately. This reduces dependencies, speeds up release cycles, and empowers businesses to respond quickly to evolving customer needs.
