Answer 1

Off the top of my head you have a few options:

• Make the on-prem services public facing
• Create a VPN connection and Integrate a Function App with an Azure Virtual Network
• Look into Azure Service Bus relay

Azure Relay service facilitates hybrid applications between on-premises and cloud environments within a corporate enterprise network and the public cloud, without having to open a firewall connection or require intrusive changes to a corporate network infrastructure.
