Client Background
NLB Bank Serbia is a leading financial institution and subsidiary of NLB Group, one of the largest banking groups in South East Europe. Serving over 500,000 customers through 120+ branches across Serbia, the bank manages assets worth €4.2 billion. As part of its digital transformation strategy, NLB Bank Serbia decided to adopt OpenShift on Azure to modernize its banking infrastructure and enhance service delivery. However, to fully leverage these technologies, the bank recognized the need to upskill its platform and development teams.
Challenge
The NLB Bank Serbia platform team faced several critical challenges in their cloud transformation journey:
Limited Cloud-Native Knowledge: Although the team was proficient in traditional banking infrastructure management, they lacked hands-on experience with containerization, Kubernetes, and cloud-native architecture patterns, which are foundational to OpenShift.
Complex Deployment Processes: Without deep understanding of modern DevOps practices, the team struggled with manual deployment processes, leading to longer release cycles and increased risk of human error in production environments.
Scalability and Performance Issues: The team needed to learn how to effectively scale banking applications and manage resources efficiently within a cloud-native environment to meet growing customer demands.
Security and Compliance Concerns: Banking regulations require strict security controls and compliance measures, which the team needed to implement within the new OpenShift on Azure environment.
Objectives
The key objectives of the upskilling initiative were:
Build Cloud-Native Foundation: Equip the platform team with essential knowledge of OpenShift, Kubernetes, and Azure integration through comprehensive workshop training.
Modernize Deployment Practices: Enable the team to implement automated CI/CD pipelines and streamline application deployment processes using OpenShift’s capabilities.
Enhance Scalability and Performance: Train the team to effectively manage, scale, and optimize banking applications within the OpenShift environment.
Implement Security Best Practices: Ensure the team can maintain banking-grade security and compliance standards in the cloud-native environment.
Solution
