Hybrid Linked Mode allows you to link your VMware Cloud on AWS vCenter Server instance with an on-premises vCenter Single Sign-On domain.
If you link your cloud vCenter Server to a domain that contains multiple vCenter Server instances linked using Enhanced Linked Mode, all of those instances are linked to your cloud SDDC.
Using Hybrid Linked Mode, you can:
Log in to the vCenter Server instance in your SDDC using your on-premises credentials.
View and manage the inventories of both your on-premises and VMware Cloud on AWS data centers from a single vSphere Client interface.
Cold migrate workloads between your on-premises data center and cloud SDDC.
Share tags and tag categories across vCenter Server instances.
