VMware HCX: A Robust and VMware-Optimized Workload Mobility Platform for Seamless Integration and High-Performance Network Extensions in Hybrid Cloud Environments.

Layer 2 network extensions bridge geographically dispersed sites, creating a unified broadcast domain for seamless communication between on-premises and cloud environments. VMware HCX, Nutanix Move, and Cisco Catalyst 8000V are prominent solutions for L2 extensions. HCX is VMware-optimized and supports high-performance network extensions, flexible migration options, and high availability. However, it is primarily for VMware environments and requires a VMware Cloud Foundation license. Nutanix Move is ideal for Nutanix environments, while Cisco Catalyst 8000V offers a hardware-based solution with integrated security features.
