An NSX gateway HA mode where one Edge node handles traffic while a second waits to take over. Stateful services such as NAT, VPN, load balancing and the stateful firewall depend on it, and VCF Automation 9.0 expects its Tier-0 to be set up this way.

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.
- HA mode
Choose between active-active, where Edge nodes share the load, and active-standby, which some stateful services like IPsec and L2 VPN demand. For a Tier-1 there is a further Distributed Only option that omits the service router.
- WHERE
Limits a SELECT, UPDATE or DELETE to just the rows meeting a condition. Omit it, and the statement hits every row.
- Take over
Only an owner can set up scheduled refresh, data source credentials and automatic aggregations for a semantic model. This action, in the model's settings in the service, transfers ownership to whoever selects it.
- Azure NAT Gateway
Gives every resource in a subnet a managed way out to the internet through one or more fixed public IP addresses, while accepting no unsolicited inbound connections. Azure Container Apps can use it only when the environment is a workload profiles one.
- VPN
Traffic sent through an encrypted tunnel across a public network, as in a site-to-site connection to a VPN gateway in an Azure GatewaySubnet.
- ELT
Extract, load, transform: raw data lands in the target system first and is transformed there. See ETL for the opposite order.
- VCF Automation
Self-service platform in VCF for provisioning VM, Kubernetes and AI workloads. Providers manage regions and tenants in one portal, while tenants handle projects and consumption in theirs.
