VMware Hybrid Cloud Extension (HCX) is the de facto VMware solution when it comes to Enterprise scale workload migration whether that is from onPrem to onPrem or from onPrem to Cloud, including our VMware Cloud on AWS (VMC) offering. In fact, one of the most popular use cases for HCX right now is datacenter evacuation/consolidation and customers are migrating their workloads to VMC because they want to get out of the business of running datacenters and get back to running their core business. This is especially attractive for customers wanting to expand to new markets without requiring the need of new datacenters. This makes a ton of sense, especially when you go beyond the initial CapEx, its the on-going OpEx costs that folks may not always be thinking about immediately and being able to easily scale up or down is not always possible for most onPrem environments.
HCX already provides a rich UI interface within the vSphere Client for scheduling migrations including the new Cloud Motion with vSphere Replication feature which was announced at VMworld US 2018.
However, it should come as no surprise that our customers are also interested in Automation, especially as it can help expedite migrations and remove potential user error, especially around mapping the destination networks which can be quite daunting for a large number of migrations. The good news is that HCX provides a Restful API that allows customers to automate all aspects of HCX including the HCX VAMI UI for initial configuration as well as consuming the HCX services which are exposed in the vSphere UI.
