ROSA (Red Hat OpenShift on AWS)
This section covers technical documentation for deploying and operating Red Hat OpenShift Service on AWS (ROSA). ROSA is a fully managed OpenShift service jointly managed by AWS and Red Hat, enabling easy deployment of enterprise-grade Kubernetes platforms.
Key Documents (Implementation Order)โ
Step 1: Cluster Installation & Configurationโ
- 1. ROSA Demo Installation
- STS (Security Token Service) based cluster creation
- Step-by-step installation using ROSA CLI
- Auto-scaling configuration
- Network and IAM role setup
- Initial cluster validation
- Lab environment setup and testing
Step 2: Security & Access Controlโ
- 2. ROSA Security Compliance
- Red Hat Hybrid Cloud Console access control configuration
- Access control strategies for financial regulatory compliance
- IdP (Identity Provider) integration and MFA configuration
- Role-Based Access Control (RBAC) setup
- Audit and logging configuration
