    Challenge

    The client needed to build new digital capabilities on cloud.

    A leading European bank wanted to digitize its core banking system to offer functionalities such as payments, loans and credit processing through online and mobile channels. They wanted to build a scalable distributed banking system for greater agility and increased transactional speed. The legacy architecture did not support frequent release of next-gen applications and features. There was a need to build new digital capabilities with better security, scalability and availability without incurring any downtime post digitalization.

    Solution

    The banks deploys microservices in Kubernetes cluster for secure and upgraded architecture.

    TCS elevated the security posture of the bank, which helped to reduce the cyberattack surface, without any service disruptions. TCS re-architected Java applications hosted in EC2 to microservices, developed front-end UI for a mobile platform, and designed infrastructure to stream high velocity of customer requests by deploying Kafka nodes on AWS EKS clusters. By automating the foundation through Terraform, TCS built the AWS account structure to host the business applications, Kafka nodes and microservices. TCS automated DevSecOps pipelines built in Jenkins and integrated with Sonar and Nexus tools to ensure the security of the new microservices architecture, further remodeling it with Kafka to decouple sender and receiver services via asynchronous messaging for a fast and reliable inter-service messaging facility. Role-based access controls (RBAC) were leveraged to secure Kubernetes API server operations and improved security posture of the AWS environment’s Kubernetes clusters.

    Benefits

    The bank is now able to respond to customer requirements across channels in real time. TCS helped the client adopt microservices-based architecture for accelerated delivery of applications and features. By supporting the creation of dedicated identity and access management roles, TCS also regulated user access into the bank’s AWS environment.

    Value delivered

    The client now enjoys:

    • Accelerated delivery of applications and features
    • Improved responsiveness for payments and loans 
    • Reduced enterprise attack surface through fine-grained IAM roles
    • Accelerated time-to-market through automated security checks in 
    • Easy identification of vulnerabilities in application development cycle
