Cloud Routing

Cloud routing refers to how traffic is directed between subnets, virtual networks, on-premises environments, and the Internet within a cloud platform. Each cloud provider uses route tables (collections of rules that determine where traffic destined for specific IP ranges should be sent) to control the flow of packets through the virtual network. Cloud routing also involves dynamic routing protocols through services like AWS Transit Gateway, Azure Route Server, or GCP Cloud Router, which use BGP to exchange routes automatically between cloud and on-premises environments, making large hybrid network architectures manageable without manual route configuration.
