Azure Service Endpoint

Azure Service Endpoints are used to optimize routing on your subnet to the service it has been configured to reach on a subnet in a Azure Virtual Network.
It only only offers this access to devices on the Subnet itself, and can not be used outside of the Subnet (Natively).
A key usage is to simplify routing when using UDR's to stop traffic routing to a RouteAll.

A Service Endpoint Policy can be configured to restrict access to only the allowed Storage Accounts through the Service Endpoint.
