Challenge

Managing multiple OpenShift clusters without a centralized control plane increases complexity, security risks, and inefficiencies. Organizations need a scalable, cloud-native management solution to simplify administration and enhance security.

Solution

I designed and deployed an OpenShift Management Cluster on AWS, serving as a centralized hub for managing multiple OpenShift environments. Using Infrastructure-as-Code (IaC) principles with Terraform, Ansible & Red Hat Advanced ClusterManagement for Kubernetes, I automated the provisioning and configuration processes to ensure consistency and efficiency.

I implemented a dedicated Keycloak authentication server, which was connected to the existing Identity Management (IDM) system. This provided seamless authentication and fine-grained access control tailored to organizational requirements.

To enhance security, I implemented encrypted storage solutions and optimized networking with AWS VPC peering and service mesh integration. Observability was improved through Prometheus, Grafana, and AWS-native logging services, enabling real-time monitoring and proactive issue resolution.

Results

  • Centralized management for multi-cluster OpenShift environments
  • Improved security with Keycloak integration and automated policy enforcement
  • Faster cluster provisioning through Infrastructure-as-Code automation
  • Enhanced observability with real-time monitoring and alerting
