 by using the native integrations with
VMware Cloud Director
 and VMware
vCenter Server
®.

VMware Cloud on AWS
 Design Implications

Due to design specifics of the
VMware Cloud Director service
 hosted at
VMware Cloud on AWS
,
VMware Cloud Director Availability
 introduces a service named
Data Engine Service
 for performing migrations with
VMware Cloud on AWS
 by using the
VMC
 data engine. For information about this service, see Services and network ports in the
Security Guide
. For information about both the
VMC
 and the
Classic
 data engines, see Activate the data engines for replicating workloads in the
Administration Guide
.
By using the
Data Engine Service
 and activating the
VMC
 data engine,
VMware Cloud Director Availability
 4.2 and later can migrate workloads to
VMware Cloud Director service
.
VMware Cloud Director Availability
 4.6 and later also allow migrating workloads from
VMware Cloud Director service
 back to the on-premises
vCenter Server
 site. For information about the replications use cases and their cross-site support, see Replicating workloads in the
User Guide
.
As a
provider
 in
VMware Cloud on AWS
 you have a VMware Cloud SDDC account and a general AWS account, and the two accounts must be linked for the service to work. Each account has its own virtual private cloud (VPC), and the VMware Cloud VPC contains a management and a compute resource pool. In the management resource pool, VMware has complete administrative control over the management and the infrastructure components. The
VMware Cloud Director Availability
 appliances reside outside the management resource pool, deployed and managed by the
provider
.

Migration with
VMware Cloud Director service

Both the providers and their tenants, can use the existing migration flow and migrate their workloads to
VMware Cloud Director service
 in
VMware Cloud on AWS
 after following this
Migration with VMware Cloud Director service Guide
