AWS Route Tables
AWS Route Tables are a core networking component in Amazon Virtual Private Cloud (VPC) that define rules (routes) for directing network traffic from subnets to destinations, such as the internet, other VPCs, or on-premises networks. They determine how traffic is forwarded within a VPC and to external networks, enabling connectivity and routing control. Each subnet in a VPC must be associated with a route table to function properly.
Developers should learn AWS Route Tables when building or managing cloud infrastructure on AWS, as they are essential for configuring network routing in VPCs, ensuring secure and efficient communication between resources. Use cases include setting up internet access for instances via internet gateways, connecting to on-premises data centers through VPNs or Direct Connect, and implementing complex network architectures like hub-and-spoke models. Mastery is crucial for roles involving cloud architecture, DevOps, or network engineering on AWS.
