Overview

Following a recent incident, Khan Bank promptly devised a comprehensive plan to address performance issues. Immediate measures included disabling consul discovery, optimizing cache management on the OCH frontend, and segregating Redis. Simultaneously, a long-term transformation plan involving OCH containerization was outlined.

To swiftly enhance performance, the bank first disabled consul discovery and implemented a traditional configuration method, resulting in a notable reduction in loading balancer processing time. Additionally, caching API data from OMNI channel HUB configuration on middleware mitigated the impact on backend servers, accelerating web and application processing. A thorough performance bottleneck analysis prompted the implementation of Back-end cache segregation (Redis segregation), leading to improved performance and increased system endurance.

With aspirations to become a fully digital bank offering innovative services, Khan Bank prioritizes stable, error-free operations. The adoption of cloud-native technology on OCH has proven advantageous, providing stability, reliability, auto-scaling, self-healing, and zero downtime. The OCH containerization project, designed to automate scaling, reduce application startup time, enable automated CI/CD, and streamline deployments, promises separate maintenance and troubleshooting of servers, aligning with the bank’s commitment to optimal performance in its digital transformation journey.

Implementation Process

The OCH containerization project was effectively executed, leveraging advanced technologies, notably the Mirantis Kubernetes runtime platform (formerly Docker Enterprise/UCP). This platform facilitated the rapid and seamless deployment of cloud-native applications at scale across diverse environments for Khan Bank.

The successful integration of Azure DevOps into the project ensured smooth coordination among various automation, continuous integration (CI), and continuous delivery (CD) platforms, resulting in the flawless implementation of system changes.

Jenkins, functioning as the CI/CD automation server, played a crucial role in the project’s execution. The migration of four core backend services to Docker Kubernetes runtime technology was completed, aligning with cloud-native requirements. This encompassed defining the features and specifications of the backend services and seamlessly integrating them into the existing containerization runtime platform. The outcome was a suite of lightweight, auto-scaling, self-healing, and zero-downtime containers, achieved through robust CI/CD processes.

Benefits Achieved

• Disabled consul discovery and implemented a traditional configuration method, reducing load balancer processing time from 10-15 minutes to 1-2 seconds.
• Saved API data from OMNI channel HUB configuration on middleware as cache, resulting in a 15% reduction in impact on backend servers and a 25% acceleration in web and application processing.
• Conducted a thorough analysis of performance bottlenecks and implemented a back-end cache segregation process.
• Improved Redis performance by 10 times.
• Increased system endurance from 2500 TPM to 7000 TPM.

Conclusion

Finacle’s product, OCH, serves as the cornerstone of this transformative technology, seamlessly facilitating financial and non-financial transactions for the majority of Mongolian citizens. This positions Khan Bank at the forefront of digital transformation, setting a precedent among other commercial banks.
