To ensure secure and operational connectivity between the SDDC components, you apply signed certificates provided by a Microsoft Certificate Authority for the SDDC components.

You use SDDC Manager to generate the certificate signing request (CSRs) and request a signed certificate from the Microsoft Certificate Authority. SDDC Manager is then used to install the signed certificates to SDDC components it manages. In order to achieve this the Microsoft Certificate Authority must be configured to allow integration with SDDC Manager.
