VPN gateways

A VPN gateway is a specific type of VNet gateway that is used to send traffic between an Azure virtual network and an on-premises location over the public internet. You can also use a VPN gateway to send traffic between VNets. Each VNet can have only one VPN gateway.

Azure VNet <-> on-premises
Azure VNet <-> Azure VNet (Different Subscription)

Border gateway protocol

An on-premises network gateway can exchange routes with an Azure virtual network gateway using the border gateway protocol (BGP). BGP with site-to-site VPN connections

Support multiple tunnels between a VNet and an on-premises site with automatic failover based on BGP

Azure WebJobs

Triggered

Starts only when triggered manually or on a schedule.
Runs on a single instance that Azure selects for load balancing.

Continuous

Starts immediately when the WebJob is created. To keep the job from ending, the program or script typically does its work inside an endless loop. If the job does end, you can restart it.
Runs on all instances that the web app runs on. You can optionally restrict the WebJob to a single instance.
Supports remote debugging.
