Application Gateway v2

Application Gateway v2 allows for automatic scale-out, which allows you to scale out with the Azure CLI if the setting is set to manual scale-out.

• Check the current number of instances

az network application-gateway show -g westeu-test-rg -n appgwv2test --query "sku"

• Manually scale out Application Gateway v2 to two instances. Specify the number of instances you want to run with sku.capacity. Application Gateway can obtain 99.95% SLA with 2 or more instances for both v1 and v2.

Application Gateway v1

• Check the current number of instances and tier

• Scale up Application Gateway v1 from small to medium tier. We have several variants to choose: Standard_Large, Standard_Medium, Standard_Small . Applying the configuration usually takes 15 minutes, it obviously depends on the region in which Application Gateway is implemented.
