Raiffeisen Bank International (RBI) is a leading corporate and retail bank operating across Central and Eastern Europe, with subsidiaries in 13 markets. It offers a broad range of financial services to retail, corporate, and institutional clients. RBI is known for its commitment to innovation, digital transformation, and maintaining high standards in customer experience and regulatory compliance.
As part of its digital transformation strategy, RBI was an early cloud adopter, with 50% of its infrastructure already migrated to AWS at the time of this project. Some group entities had reached as much as 70% cloud adoption. However, Raiffeisenbank Czech Republic (RBCZ) needed to accelerate its own cloud journey to align with group-wide progress and strategic goals.
Key business drivers included:
- The need for greater agility and faster time-to-market of digital services
- Delivering a first-class customer experience to remain competitive in the financial sector
- Meeting investor expectations and demonstrating technological maturity
- Achieving HQ-defined targets for cloud adoption
- Realizing positive business impact through increased efficiency and innovation
- Improving security posture and compliance
- Scaling cloud capabilities and teams to support rapid development and operational needs
Trask Solutions, an AWS Advanced Tier Services Partner, was engaged to re-architect RBCZ’s key public-facing web application as part of its broader cloud modernization effort. The solution focused on a complete AWS native redevelopment of the customer-facing web platform — a highly customized website that handles large traffic spikes and fluctuating user demand.
To ensure performance, scalability, and operational efficiency, the solution included:
1) Cloud-Native Architecture & Performance Optimization
- Containerization and use of cloud-native services for modularity, resilience, and faster deployments
- Deployment on AWS Graviton-based compute instances for optimized performance and cost savings
- Migration of databases from MS SQL to Amazon Aurora PostgreSQL to boost scalability, performance, and reduce license costs
- Refactoring of Lucene Search to Amazon OpenSearch Service for scalable, high-speed search
2) Automation & Serverless Efficiency
- Use of Amazon ECS (Elastic Container Service) for efficient container orchestration
- Implementation of AWS Lambda to support serverless workflows and minimize infrastructure overhead
- Automation of infrastructure provisioning and deployment pipelines using DevOps best practices and infrastructure-as-code
- Deployment of AWS CloudFormation templates to standardize and automate infrastructure provisioning
3) Scalability, Security & Data Management
- Utilization of Amazon S3 for secure, durable, and highly available object storage
- Integration of AWS networking services to ensure reliable and scalable connectivity
- Comprehensive migration of legacy components and data to AWS with zero business disruption
- Implementation of AWS API Gateway to securely expose APIs and enable external integration
This end-to-end modernization enabled RBCZ to deliver a high-performing, cloud-native platform aligned with the bank’s strategic transformation goals and AWS architectural best practices.
- Increased agility in application development and release cycles
- Faster time-to-market for digital services
- Enhanced customer experience, even under heavy and unpredictable traffic loads
- Alignment with investor and HQ expectations regarding digital maturity and performance
- Strengthened cloud security posture
- Scaled-up internal cloud expertise and team capabilities
