94  Red Hat OpenShift and IBM Cloud Paks on IBM Power Systems: Volume 1 8459ch05.fm Draft Document for Review December 11, 2019 1:55 pm The architecture consists of the following components: GLYPH<SM590000> PowerVC : Provide Infrastructure as a service and manage: GLYPH<SM590000> Deployment host:  RHEL 7.6 for POWER8 and RHEL-ALT 7.6 for POWER9 minimum  installation. Responsible for deploying one or more OpenShift Container Platform  environments: GLYPH<SM590000> Load balancer:  RHEL 7.6 for POWER8 and RHEL-ALT 7.6 for POWER9 minimum  installation. HAproxy offers a single entry point for the many Red Hat OpenShift Container  Platform components. GLYPH<SM590000> Master-Infrastructure : RHEL 7.6 for POWER8 and RHEL-ALT 7.6 for POWER9 minimum  installation. Responsible for running the OpenShift master and infrastructure components,  including the API server, controller manager server, etcd, registry and routers.  GLYPH<SM590000> Worker:  RHEL 7.6 for POWER8 and RHEL-ALT 7.6 for POWER9 minimum installation.  Responsible for running Application containers created by the end users of the OpenShift  service. Note:  The HAProxy Load Balancer is intended to demonstrate the API server’s HA  mode and is not recommended for production environments. If you are deploying to a  cloud provider, Red Hat recommends deploying a cloud-native TCP-based Load  Balancer or take other steps to provide a highly available Load Balancer. – Terraform for deploying PowerVC infrastructure (network, storage, virtual machines). – OpenShift-Ansible for deploying OpenShift Container Platform – Storage backends. – Dual SAN Fabrics Brocade or Cisco. – IBM Power Systems (PowerVM): 2 x Virtual I/O Servers: 2 cores configured in  dedicated donated mode and 16 GB Memory. 2 x Ethernet cards and 2 x Fibre  Channel cards for each VIO Server.
