Amazon VPC Internet Gateway Icon

An Amazon Virtual Private Cloud (VPC) Internet Gateway is a horizontally scalable, managed AWS service that enables communication between your instances within a VPC and the internet. It acts as a router, allowing your instances to send and receive traffic to and from the public internet. You don't manage it directly; AWS handles the underlying infrastructure. It's essential for VPCs that need external connectivity, such as web servers or applications that need to interact with the outside world.
