With increasing transaction volume, ensuring the system could scale smoothly was a major concern.
Load Handling
Simulating realistic load and traffic patterns for accurate performance benchmarking and ensuring the system could handle peak traffic loads.
SSL Integration and Security
The solution also ensured that all bank integrations with Bangladesh Bank over Private SSL were smooth, providing secure communication channels while complying with regulatory security requirements.
Load Testing
API Load Generation
Tirzok conducted load testing by simulating API requests to the DirectPay API of the Binimoy platform. This testing was designed to mimic real-world usage patterns, with a focus on transaction volume and response times under varying levels of load.
Performance Benchmarking
The testing focused on identifying key performance metrics, including response time, error rates, and throughput. The goal was to ensure the Binimoy platform could handle significant traffic spikes while maintaining low latency and high reliability.
Stress Testing and Reporting
The load testing was extended to stress-test the system beyond its expected operational capacity, revealing potential weaknesses in the architecture. Detailed reports were generated, highlighting the platform’s performance at different load levels and providing actionable insights to optimize the system further.
Results
High Availability and Performance
The Active-Active NGINX Plus Cluster ensured that API traffic was always available and balanced efficiently across the servers, with minimal downtime and fast recovery in the event of failures. This enhanced the reliability of the Binimoy platform, ensuring it met the rigorous uptime requirements of financial institutions.
Scalable Architecture
The load testing revealed that the platform could handle large volumes of API requests with high scalability. Performance benchmarks were achieved without significant degradation in user experience, even under high traffic loads.
Security Compliance
The SSL setup and Private CA server ensured that all data transmitted between the participating banks and Bangladesh Bank remained secure. The integration of Private SSL certificates helped maintain the confidentiality, integrity, and authenticity of the data exchanged across the platform.
Informed Decision-Making
The load testing results provided Fintech Solutions Limited with valuable insights into the performance of the Binimoy platform under stress. This empowered them to make informed decisions about infrastructure scaling and optimization.
Conclusion
Tirzok Private Limited’s deployment of the NGINX Plus Active-Active Cluster and load testing for the Binimoy platform was a resounding success. By ensuring high availability, security, and scalability, the project helped prepare the Binimoy platform for future growth while ensuring it met the stringent operational requirements of Bangladesh’s financial ecosystem.
This project not only reinforced the Binimoy platform’s capabilities as a robust financial transaction solution but also contributed significantly to Bangladesh Bank’s efforts in fostering a secure and efficient digital payment infrastructure across the nation.
