VMware Cloud on AWS supports either a standalone service with separate authentication methods or an integrated authentication and access method with both the VMware Cloud Portal and the VMware Cloud on AWS SDDC environment.
Organizations can configure the VMware Cloud Portal authentication to leverage an organization's primary identity authentication method and grant access to VMware Cloud services. Additional information can be accessed at Enterprise Federation information.
In addition, an SDDC can be configured to use an organization's existing identity management solution similar to how vSphere on premise is connected to an authentication source. This is accomplished through the SDDC's CloudAdmin default administration account. Read detailed information at Configuring Hybrid-linked mode.
