Executive Summary
A top-tier bank in Central and Eastern Europe (CEE), serving over 14 million customers, partnered with mindit.io to modernize its digital infrastructure. With legacy systems limiting innovation, scalability, and performance, the bank sought to migrate key applications to the cloud. The goal was not just to modernize—but to future-proof the organization’s digital backbone.
mindit.io supported this transformation through a structured cloud migration program focused on application modernization, improved execution speed, reduced operating costs, and enhanced security. The result: faster services for 2.3 million platform users, operational cost savings, and a scalable foundation for future innovation.
Key Results:
- Seamless migration of business-critical applications to the cloud
- Faster execution and reduced load times for 2.3 million platform users
- Stronger cybersecurity controls aligned with financial industry standards
- Lower infrastructure and maintenance costs
- Future-ready platform supporting continuous delivery and scalability
About the Client
Our client is a major financial institution and a market leader in Central and Eastern Europe, employing more than 45,000 professionals and serving over 14 million customers across the region. With decades of operations and a strong regional presence, the bank had built a large digital ecosystem—but one that relied heavily on aging infrastructure.
To stay competitive in a rapidly evolving financial landscape, the client launched a strategic modernization initiative focused on cloud migration and DevOps transformation.
The Challenge
The project presented multiple layers of complexity, both technical and organizational:
- Legacy Infrastructure: Applications ran on outdated infrastructure that limited performance and scalability
- Functional Migration Risks: Ensuring 100% functional parity in the new cloud environment was critical to avoid customer-facing disruptions
- Delivery Complexity: The scope included the migration of numerous interdependent applications, all of which needed to be moved without impacting end-user experience
- Security & Compliance: As a financial institution, the client had strict regulatory and data protection requirements that had to be upheld throughout the migration
- Cultural Shift: Moving to the cloud also required a change in delivery mindset—from static releases to continuous integration and agile delivery
Project Goals
mindit.io’s objective was to support the successful migration of the bank’s applications to a secure, scalable cloud environment. This transformation aimed to:
- Modernize Core Applications: Move legacy workloads to cloud-native architecture
- Accelerate Time-to-Value: Improve execution speed and reduce application load times
- Reduce Operational Overhead: Minimize infrastructure maintenance costs
- Ensure High Security & Compliance: Meet banking-grade security standards throughout the cloud journey
- Enable Future Innovation: Build a foundation for continuous delivery, AI enablement, and digital scalability
mindit.io’s Solution
To meet the client’s objectives, mindit.io deployed cross-functional teams combining Java development, DevOps engineering, and manual QA under an Agile/Scrum delivery model. The teams focused on:
- Cloud-Ready Refactoring: Ensured that applications were optimized for cloud scalability and maintainability
- Seamless Functional Migration: Migrated critical functionalities without impacting business continuity
- DevOps Automation: Introduced CI/CD pipelines for faster and safer deployment cycles
- Enhanced Security Architecture: Applied multi-layered security measures, including encryption, identity access management, and real-time monitoring
- User Performance Optimization: Focused on reducing latency and load times for 2.3 million platform users
Implementation Process
The migration project was structured into multiple sprints, guided by Agile methodology and clear success metrics:
- Discovery Phase: Conducted deep analysis of legacy applications and infrastructure to define migration paths
- Stakeholder Workshops: Engaged business and IT teams to prioritize apps, validate features, and align migration plans
- Cloud Architecture Design: Defined secure, scalable infrastructure aligned with regulatory frameworks
- Incremental Migration: Migrated applications in phases to minimize disruption
- Validation & Testing: QA teams ensured full functional coverage before and after migration
- DevOps Enablement: Established automated pipelines to streamline post-migration releases
Results
The transformation yielded significant business and technical improvements:
- Accelerated Performance: Reduced page load times and improved backend responsiveness for over 2.3 million platform users
- Operational Savings: Lowered infrastructure and maintenance costs post-migration
- Security & Compliance: Deployed best-in-class cloud security practices and met regulatory obligations
- Scalability & Resilience: Applications were now scalable on demand, enabling agile response to usage spikes
- Foundation for Growth: Established a modern delivery environment that supports DevOps, AI, and future innovation
Client Testimonial
