Terms in this definition
- NSX
Software that handles networking and security across VCF, covering firewalling, load balancing, NAT, VPCs, overlay segments and Tier-0/1 gateways.
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- segment
A layer 2 network in NSX for VM connections. Overlay-backed ones carry traffic in tunnels between TEPs; VLAN-backed ones correspond to a physical VLAN.
- VLAN
Layer 2 broadcast domain tagged using 802.1Q. In VCF they carry TEP, vSAN, vMotion and management traffic, and NSX can back segments with them.
Related terms
- Distributed router
Half of an NSX Tier-0 or Tier-1 gateway: the portion present on every transport node of the transport zone, so packets are routed inside the hypervisor. Anything needing a central point lives in the service router (SR) on Edge nodes.
