Overview

As a leading payment gateway service provider in Myanmar, the company is committed to delivering a secure, reliable, and seamless digital payment experience for businesses and consumers. With the increasing adoption of online transactions, ensuring high availability, security, and compliance has become a top priority. The payment infrastructure must support growing transaction volumes while maintaining operational efficiency, data protection, and adherence to financial regulations.

Key Challenges

The payment gateway service faced several key challenges in maintaining a secure, scalable, and efficient transaction processing system. As transaction volumes increased, ensuring scalability and performance became critical to handle high loads while minimizing latency. Security and compliance remained a top priority, requiring robust measures to protect sensitive payment data and adhere to financial regulations.

The need for continuous deployment and reliability posed another challenge, as frequent updates had to be deployed seamlessly without causing service disruptions. Additionally, maintaining visibility and observability across the system was essential to detect transaction anomalies, monitor performance, and address potential security threats in real time. Finally, cost optimization was a key concern, as balancing cloud resource utilization while keeping operational expenses under control was necessary for sustainable growth.

Solution

To tackle challenges related to performance, scalability, and cost efficiency, the company chose Amazon Web Services (AWS) as its preferred cloud platform. After a thorough assessment of AWS consulting partners, B8 ICT Solutions was selected for its expertise and proven track record in building robust infrastructures for large-scale, multi-industry enterprises. Through a series of strategic workshops and in-depth consultations, B8 ICT Solutions gained a deep understanding of the company’s business and technical objectives, ultimately designing a resilient and scalable microservices architecture to support the DevOps initiative.

The figure illustrates a comprehensive microservices architecture, integrating a CI/CD pipeline to facilitate the implementation of both DevOps and GitOps practices.

B8 ICT Solutions has adopted a microservices architecture with DevOps and GitOps methodologies to support the growing demands of its payment gateway service. Amazon EKS (Kubernetes) is at the core, providing efficient application deployment and scalability.

A CI/CD pipeline powered by GitHub Actions automates the build and testing processes, with ArgoCD handling continuous deployment. Amazon ECR stores container images, and Helm Charts define application configurations.

For databases, Amazon Aurora RDS is used in production, while a staging environment runs on an EC2 instance. CloudWatch and Grafana Loki provide monitoring and logging, with data stored securely in Amazon S3. Cloudflare manages DNS for security and performance.

This architecture ensures scalability, automation, and real-time monitoring, allowing for seamless application deployment and efficient resource utilization.
