Overview

Recognizing the surge in demand for online services, the bank has proactively upgraded its digital banking infrastructure by migrating to the AWS Cloud platform. This move improved operational efficiency, addressed cost, security, and performance challenges, and ensured a more optimized and secure banking experience for customers.

Key Challenges 

As a leading commercial bank in Phnom Penh, Cambodia, the bank aims to provide a diverse range of banking services to individual customers, small and medium-sized enterprises (SMEs), as well as large corporate clients. With a strong commitment to innovation and customer service quality,  the bank continually strives to improve its digital banking infrastructure to meet the ever-increasing market demands. However, it faced two key challenges in data storage operations.

Firstly, the bank processed a large volume of daily transaction data through its online service portal in the context of rapidly evolving digital banking, which created significant pressure on the system. The on-premises system not only struggled to handle large volumes of data but also had limited scalability that failed to meet the diverse and growing service demands of customers. Additionally, maintaining an on-premises infrastructure resulted in higher costs, which limited opportunities for operational optimization and strategic investments.

Solution

To overcome challenges related to performance, scalability, and cost efficiency, the bank adopted Amazon Web Services (AWS) as its cloud platform for transformation. After thoroughly evaluating AWS consulting partners, the bank chose Renova Cloud due to its experienced team and proven track record in designing infrastructure for large, multi-sector enterprises. After a series of workshops and interviews to better understand the bank’s business and technical requirements, Renova Cloud decided to implement a rehost and re-platform strategy for this migration project.

As part of this modernization, the Nginx load balancer was replatformed to AWS Application Load Balancer (ALB), allowing automatic scaling, seamless AWS service integration, and improved security, thereby reducing operational complexities

The migration to AWS’s cloud computing platform solved bottlenecks in the bank’s legacy infrastructure by utilizing AWS MGN (Application Migration Service) to smoothly transition client’s application servers without extensive redesign, ensuring minimal downtime and no disruption to the bank’s operational transactions. Simultaneously, Renova Cloud implemented the AWS Database Migration Service (DMS) to efficiently migrate massive data volumes from on-premises to the cloud, facilitating a streamlined data migration process, minimizing impact on daily operations, and enhancing customer experience.

Moreover, the deployment of Amazon RDS (Relational Database Service) by Renova Cloud optimized the bank’s transaction processing speed, especially during peak periods. This optimization ensured that customers experienced faster and more reliable services, enhancing customer satisfaction and maintaining the bank’s competitive edge in the financial industry. It can be said that Amazon RDS has helped the bank automate security patching to improve performance, increasing overall operational efficiency.

 Key technologies in the bank’s digital transformation include:

  • EC2 (Elastic Compute Cloud): Provides flexible and easily scalable computing infrastructure.
  • RDS (Relational Database Service): Simplifies management and enhances database performance.
  • DMS (Database Migration Service): Supports seamless database migrations.
  • MGN (Application Migration Service): Restructures existing applications without redesigning.
  • WAF (Web Application Firewall): Strengthens network security.
  • Fortinet devices: Adds layers of security and enhances firewall management.

Benefits

By leveraging AWS’s optimized strategies and robust solutions, the Bank has not only built a flexible, scalable platform but has also achieved remarkable business outcomes across financial, operational, and performance areas:

Financial Benefits:

  • Realizes over 10% savings by moving away from traditional infrastructure, reducing costs significantly.
  • Boosts customer experience, attracting more users and supporting sustainable business growth.

Operational Benefits:

  • Removes the burden of managing operating systems and databases, allowing the team to focus on core business activities.
  • Enhances scalability, making it easy to adjust IT resources according to demand.
  • Strengthens data and application security with comprehensive AWS protections.

Performance Improvements:

  • Increases operational efficiency by approximately 20% through AWS’s modern hardware, featuring high-performance CPUs, memory, and SSDs.
  • Ensures flexible scaling to accommodate high volumes of requests as business needs grow.

This strategic partnership positions the bank to drive further innovation, stay agile in a dynamic market, and continue delivering top-tier service and security to its customers..

Conclusion

The integration of AWS’s advanced technologies, combined with Renova Cloud’s dedicated support, provided the bank with a robust foundation for achieving exceptional cost efficiency and operational optimization. This transformation enhanced the bank’s ability to respond swiftly to complex business demands.

With a flexible, secure, and scalable cloud platform, the bank is well-positioned to develop additional digital applications, drive innovation, and prepare for future growth.
