VPC connection

Basic concepts

• AWS Direct Connect

AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS.

• AWS Vpc Peering

A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses.

• AWS privateLink

You can create your own application in your VPC and configure it as an AWS PrivateLink-powered service (referred to as an endpoint service). Other AWS principals can create a connection from their VPC to your endpoint service using an interface VPC endpoint. You are the service provider, and the AWS principals that create connections to your service are service consumers.

Establish private connectivity between VPCs and services hosted on AWS or on-premises, without exposing data to the internet.
