Re-architecting a Monolithic Core Banking System for a FinTech Leader
Client Overview: A leading enterprise financial services provider was struggling with a rigid, on-premise monolithic core banking application. The system was slow, expensive to maintain, and couldn't support the rapid launch of new digital products, putting them at a competitive disadvantage.
The Challenge: The primary challenges were ensuring zero downtime during migration, meeting stringent PCI DSS and data privacy regulations, untangling decades of complex business logic, and integrating with a modern ecosystem of third-party APIs.
Our Solution: We implemented a phased strangler fig pattern to incrementally decompose the monolith into a cloud-native microservices architecture on Microsoft Azure. Our DevSecOps team built a secure, compliant infrastructure using Infrastructure as Code (Terraform) and established a robust CI/CD pipeline for automated deployments. We migrated terabytes of sensitive financial data using a proven, multi-stage validation process.
Replatforming an E-commerce Platform for a Mid-Market Retailer
Client Overview: A fast-growing online retailer's on-premise Magento platform couldn't handle peak traffic during holiday seasons, leading to lost sales and a poor customer experience. The infrastructure was not scalable, and managing it was a significant operational burden.
The Challenge: The key goals were to achieve auto-scaling capabilities to handle traffic spikes, improve page load times, reduce infrastructure management overhead, and seamlessly migrate millions of customer and product records without impacting ongoing sales.
Our Solution: We executed a "Replatform" strategy, migrating their e-commerce business to a containerized solution running on Amazon Web Services (AWS) using Amazon EKS. We moved their product catalog and customer data to Amazon Aurora for enhanced performance and scalability. By implementing a CDN (CloudFront) and optimizing the front-end, we drastically improved site speed.
Rehosting a Core Application for a Rapidly Growing SaaS Company
Client Overview: A B2B SaaS startup had quickly outgrown its initial infrastructure, which consisted of a single, manually-configured server. They were facing frequent outages, had no disaster recovery plan, and couldn't scale to onboard larger enterprise clients.
The Challenge: The company needed a fast, cost-effective migration to a scalable and reliable cloud environment. The primary objective was to improve stability and establish a foundation for future growth without a costly and time-consuming application rewrite.
Our Solution: We performed a "Rehost" (lift-and-shift) migration to Google Cloud Platform (GCP). We moved their application to a managed instance group for auto-scaling and high availability. We also implemented Cloud SQL for their database and set up automated backups and monitoring, providing a robust and resilient platform with minimal changes to the application code.

Frequently Asked Questions
Clear answers to common questions about application modernization.
We employ several strategies, including blue-green deployments, canary releases, and phased rollouts. Our process includes creating a detailed rollback plan and conducting extensive testing in a staging environment that mirrors production. For data migration, we use techniques like change data capture (CDC) to keep data in sync until the final cutover, minimizing the downtime window to minutes, not hours or days.
That's a very common scenario. Modernization is not an all-or-nothing proposition. Our initial assessment is designed to identify the highest-impact, lowest-effort changes. We can start with a simple Rehost (lift-and-shift) to achieve immediate cost savings, followed by incremental Replatforming or Refactoring of specific components over time, aligning with your budget cycles.
This is a critical part of our discovery phase. We conduct in-depth workshops with your subject matter experts and use specialized tools to analyze the existing codebase to extract and document business rules and logic. We believe in a collaborative approach, ensuring that your invaluable domain knowledge is preserved and enhanced in the new system.
The "best" platform depends entirely on your specific needs. We are cloud-agnostic and have deep expertise in all three major providers. Our recommendation is based on factors like your existing technology stack (e.g., Microsoft shops often lean towards Azure), specific service requirements (e.g., AI/ML needs might favor GCP), cost models, and your team's existing skill set.
Timelines vary based on complexity, but a typical project follows this pattern:
- Assessment & Roadmap: 2-4 weeks
- Phase 1 (MVP Migration): 8-12 weeks for a Rehost or simple Replatform.
- Phased Refactoring: Can be an ongoing process of 3-6 month sprints, tackling different parts of the application over time.
We provide a detailed project plan with clear milestones after the initial assessment.
