An App Service app runs in an App Service plan, and App Service plans are deployed into one of the deployment units in the Azure infrastructure (internally called a webspace). Embed security in your developer workflow and foster collaboration between developers, security practitioners, and IT operators. Multiple subnets within the same virtual network can either use different NAT gateways or the same NAT gateway. Deliver ultra-low-latency networking, applications and services at the enterprise edge. Figure 1: Source network address translation by NAT gateway: connections going to the same destination endpoint over the internet are differentiated by the use of different source ports. Increase availability by distributing resources within and across zones. When a NAT gateway is associated to a public IP prefix, it automatically scales to the number of IP addresses needed for outbound. If more than one NAT gateway were to be attached to the same subnet, the subnet would not know which NAT gateway to use to send outbound traffic. See Create a public standard load balancer to get started with using a load balancer. To view a video on more information about Azure Virtual Network NAT, see How to get better outbound connectivity using an Azure NAT gateway. Reuse to a different destinationconnect outbound immediately. To learn more, see Port Reuse Timers. Valid characters are.
