Hassle-free Microservices Migration to Bare Metal Kubernetes Environment for a Reputed Indian bank
A leading Indian bank aiming to expand its presence and offer financial services to untapped markets. It’s focused on empowering individuals and businesses to reach their full potential with tailored financial solutions.
The Problem Statement
The client faced the challenge of migrating over 150 microservices and their dependencies to a bare-metal Kubernetes environment while adhering to strict compliance regulations that prohibited internet usage. Ensuring disaster recovery readiness, maintaining consistency between production and disaster recovery environments, and automating the migration process were critical requirements.
Challenges
Solutions
To address the client's challenges and enhance the scalability, security, and efficiency of their infrastructure, the following solutions were implemented:
Migrated five different environments—development, quality assurance, user assessment testing, production, and disaster recovery—to a bare-metal Kubernetes setup using Jenkins and ArgoCD.
Simplified source code updates by creating a shared library for Jenkins Pipelines.
Enabled parallel deployment of applications in production and disaster recovery environments.
Used Redis for scalable data caching and messaging in applications.
Integrated Keycloak for SSO and Kubeaudit for CIS benchmark testing of Kubernetes.
Set up complete monitoring using Prometheus and Grafana.
Implemented Velero for automated backup and recovery of critical banking applications on Kubernetes.
Enhanced security and compliance with Istio for microservices management.
Enabled secret management using Vault and Consul.
Improved manageability of multiple microservices through code segregation.
Developed an automated pipeline for Kubernetes certificate management and security event handling.
Integrated WAF into the application's load balancer for enhanced protection.
Outcomes
Migration of 150+ microservices with dependencies.
Streamlined software delivery with one-click CI/CD pipeline setup.
Achieved a 60% reduction in deployment time.
Ensured compliance with banking security and CIS benchmarks.
