This video demonstrates how to share an Amazon VPC Lattice service across AWS accounts using AWS Resource Access Manager (RAM). Tim Dormer, an AWS Solutions Architect, guides viewers through the process of creating a VPC Lattice service network in one account, sharing it with another account using RAM, and then accessing the shared service from the consumer account. The demo showcases the steps involved in creating a resource share, accepting the invitation, and configuring the necessary associations to enable cross-account access to the VPC Lattice service.
