Ensure function app is integrated with a virtual network

高レベル 1手動レビューazure

説明

Integrate function apps with a virtual network to enable access to resources in or through a non-internet-routable virtual network. This recommendation does not apply to function apps created on the consumption hosting plan, which does not support virtual networking. Integrate function apps with a virtual network for increased security and control.
