This pattern describes the use of VMware Hybrid Cloud Extension (HCX) to migrate your on-premises virtual machines (VMs) and applications to VMware Cloud on Amazon Web Services (AWS). The migration uses VMware enterprise-class software-defined data center (SDDC) software on the AWS Cloud to provide optimized access to AWS services. 

VMware Cloud on AWS integrates compute, storage, and network virtualization products (vSphere, vSAN, and VMware NSX) with VMware vCenter server management, which is optimized to run on dedicated, elastic, bare-metal AWS infrastructure. The resulting infrastructure is low-maintenance, simplified, and hyper-converged.  

With this service, IT teams can manage their cloud-based resources with familiar VMware tools. For more information, see VMware Cloud on AWS on the VMware website.

VMware HCX supports three types of cloud migrations:

• Hybridity (data center extension): Extending an existing, on-premises VMware SDDC to AWS to provide footprint expansion, on-demand capacity, a testing/development environment, and virtual desktops.

• Cloud evacuation (data center-wide infrastructure refresh): Consolidating data centers and moving completely to the AWS Cloud (including handling data center co-location or end of lease).

• Application-specific migration: Moving individual applications to the AWS Cloud to meet specific business needs.
