Create network-based partner solutions for networking, security, traffic visibility and analysis using VMware NetX virtual networking APIs.

Figure 1. Network Security Architecture

Program Overview

VMware NetX APIs are integrated into vSphere and the VMware virtual distributed switch (vDS) to provide partner access to network data flows between virtual machines (VM). This allows partners to insert their solutions either in front of specific VMs, or in front of an entire virtual data center (virtual edge).  The partner solutions can be deployed as either a physical or virtual appliance. Both virtual "in-line" (bump in the wire) or "copy only" (virtual SPAN) integration options are possible. The NetX program includes all components needed to access the APIs to create these solutions.

Key Benefits
