Before you undertake any network design, you must always consider the business requirements and use cases. Your chosen network design will be largely influenced by the chosen use cases.
VMware Hybrid Cloud Extension delivers secure and seamless app mobility and infrastructure hybridity across vSphere 5.0+ versions, on-premises and in the cloud.

HCX includes vMotion, Bulk Migration, High Throughput Network Extension, WAN optimization, Traffic Engineering, Load Balancing, Automated VPN with Strong Encryption (Suite B) and secured data center interconnectivity.
This reference architecture document will not delve into all the HCX features but will instead on the standard use cases:
A common use case for VMware Cloud on AWS is to leverage for Disaster Recovery. Many of my customers either don’t have a Disaster Recovery strategy or simply struggle to justify running a ‘ghost’ DC, just in case a disaster were to happen. The way Disaster Recovery is offered today within VMware Cloud on AWS is through an add-on (VMware Site Recovery) that leverages vSphere Replication and vSphere Recovery Manager.
Probably the most popular use case for VMware Cloud on AWS today: using it to lift and shift all applications running on a DC and moving them, untouched, to VMware Cloud on AWS. AWS would refer to this migration strategy as ‘re-hosting.’ Why would customers do this? It enables them to accelerate their move to the Cloud with no disruption to their applications and to their operating model while leveraging their existing VMware expertise.
A common use case for VMware Cloud on AWS is to leverage it to move a single application or type of applications.
As I am based in the UK, I often work with customers based in central London who face a common issue: real estate is expensive. Many of our customers are dealing with space, power or cooling constraints which means they cannot increase the size of their IT infrastructure because of expensive square footage. VMware Cloud on AWS gives them the ability to burst to the Cloud on a temporary basis (giving them time to address the capacity constraints) or permanent basis (making VMC a permanent extension to their D.C.).
