To ensure secure and operational connectivity between the SDDC components, you generate new signed certificates for the SDDC components.
You use the Certificate Generation Utility for VMware Validated Design (CertGenVVD) to generate the certificate configuration files based on the deployment specification configured in the Deployment Parameters XLS file. You then generate new certificates signed by the Microsoft certificate authority (MSCA) for all management products.
You later upload the newly generated and signed certificates to VMware Cloud Builder as part of the deployment and configuration procedure of the virtual appliance.
For information about the VMware Validated Design Certificate Generation Utility, see VMware Knowledge Base article 2146215 and VMware Validated Design Planning and Preparation for Consolidated SDDC.
