If you are deploying VMware Telco Cloud Automation in the High Availability (HA) mode, ensure that your system meets the following requirements in addition to the general system requirements.

Note: The requirements listed in this section are the minimum resource requirements for deploying VMware Telco Cloud Automation in the HA mode. The total resource requirements can vary depending on the number of domains you configure in your environment.

Bootstrapper Virtual Machines

One VMware Telco Cloud Automation bootstrapper virtual machine per management domain and workload domain. For example, a Central Site management domain has one bootstrapper virtual machine and every workload domain has one bootstrapper virtual machine.

VMware Telco Cloud Automation Cluster Running Telco Cloud Automation Manager and Telco Cloud Automation-Control Plane services

Clusters are required for running the VMware Telco Cloud Automation Manager and the VMware Telco Cloud Automation Control Plane services on different namespaces. The VMware Tanzu Kubernetes Grid cluster is where VMware Telco Cloud Automation and other third party services run.
