Now, let's begin with the NSX product. It consists of two parts: the NSX Manager and the NSX Controller.
NSX Manager is the central management pane for all NSX-related objects within the data center. It provides multiple interfaces, including a User Interface (UI) and an Application Program Interface (API). It is also responsible for installing the vSphere Installation Bundle (VIB).
The VIBs included with NSX are as follows:
- VXLAN: Provides VXLAN support to vSphere
- Distributed routing: Allows routing between VMs without leaving the NSX network
- Distributed firewall: A kernel-level firewall that can be offloaded onto a smart Network Interface Card (NIC)
