Telco Network Cloud (TNC) on Red Hat OpenShift Service on AWS (ROSA)

This article explains how to deploy Red Hat's Telco Network Cloud (TNC) management cluster on AWS using Red Hat OpenShift Service on AWS (ROSA) to manage telecommunications network functions across hybrid cloud environments.

• TNC is a reference architecture for telecom operators deploying 4G/5G network functions on OpenShift
• Management cluster deployed on ROSA provides orchestration and lifecycle management for on-premises workload clusters
• ROSA Classic Architecture required; HCP doesn't support baremetal operator needed for Zero Touch Provisioning
• Private ROSA cluster recommended for security; connected to on-premises via AWS site-to-site VPN
• Custom security groups must open ports 6385, 6183, 9999 for RHACM Zero Touch Provisioning
• AWS EBS provides block storage; S3 with private endpoint provides object storage for Quay and observability
• CoreDNS configured for bidirectional DNS resolution between ROSA and on-premises clusters
• Enables secure hybrid cloud deployment with flexible management across public cloud and on-premises

This design allows telecom operators to centrally manage distributed OpenShift clusters across hybrid environments with GitOps-based automation and comprehensive monitoring.
