VMware HCX abstracts vSphere-based on-premises and cloud resources and presents them to the applications as one continuous resource. At the core of this is a secure, encrypted, high throughput, WAN optimized, load balanced, traffic-engineered hybrid interconnect that automates the creation of a network extension.
This allows support for hybrid services, such as application mobility, on top of it. With HCX hybrid interconnect in place, applications can reside anywhere, independent of the hardware and software underneath.
