Definition: An internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between your VPC and the internet. It supports IPv4 and IPv6 traffic. It does not cause availability risks or bandwidth constraints on your network traffic. Source: Amazon Source reference: https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html Example: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): An internet gateway enables resources in your public subnets (such as EC2 instances) to connect to the internet if the resource has a public IPv4 address or an IPv6 address. Similarly, resources on the internet can initiate a connection to resources in your subnet using the public IPv4 address or IPv6 address. For example, an internet gateway enables you to connect to an EC2 instance in AWS using your local computer. eira:iopDimension: Structural IoP LOST view: TVI-Networking Infrastructure Enablers [Traceability] eira:iopSaliency: Gateway ABB is salient for technical interoperability because it physically transforms information, data and other communications from one protocol or format into another standard protocol format.
