For each infrastructure VLAN, VCF recommends a highly available first-hop gateway in the form of a floating address provided by HSRP or VRRP. HSRP itself is a first-hop redundancy protocol in which several switches share that floating gateway address.
Also called Hot Standby Router Protocol.

Terms in this definition
- 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.
- VMware Cloud Foundation
Broadcom's platform for private cloud. It unifies management of NSX, vSAN, vSphere, VCF Automation and VCF Operations as one fleet; VVF, by contrast, lacks automation and cloud management.
- First-hop gateway
The router that traffic reaches first on leaving a VLAN segment. VCF needs the data centre to supply one, with an appropriate MTU, for each infrastructure VLAN, and advises using a VRRP or HSRP virtual address that stays available through any failure the cluster model is designed to withstand.
- HSRP
The Hot Standby Router Protocol provides redundant gateways on a LAN; Azure routing does not use it.
- VRRP
A protocol giving LAN gateways redundancy; Azure VNets don't use it for routing.
- Redundancy
So that hardware failures, datacentre outages or a regional disaster cannot destroy data, Azure Storage keeps multiple copies: only in the primary region with LRS and ZRS, or in a secondary region as well with GRS and GZRS.
- Share
In OpenSharing, the container you fill with tables, views, volumes, models and notebooks for recipients. You need
CREATE SHAREon the metastore to make one; add a schema and all its assets, including later ones, go with history.
