ExpressRoute
Azure ExpressRoute provides a private, dedicated connection between on-premises networks and Azure that bypasses the public internet.
Site-to-site VPN
A site-to-site VPN is an IPsec/IKE tunnel connecting an on-premises network to an Azure VNet over the internet.
Virtual network gateway
A virtual network gateway is the Azure resource that terminates VPN or ExpressRoute connections for a VNet.
Virtual WAN
Azure Virtual WAN is a networking service that unifies connectivity through managed virtual hubs at scale.
Azure Load Balancer
Azure Load Balancer is a Layer 4 service that distributes inbound and outbound traffic across backend resources.
Application Gateway

Network security group
A network security group (NSG) filters inbound and outbound traffic to Azure resources with allow and deny rules.
Azure Firewall
Azure Firewall is a managed, stateful network firewall service for VNets and Virtual WAN hubs.
Web Application Firewall
A Web Application Firewall (WAF) protects web apps from common exploits and can run on Application Gateway or Front Door.
