VPC Lattice is an application-networking service that connects, secures, and monitors service-to-service communication across VPCs and accounts — without complex networking setup like peering or Transit Gateway.

What it simplifies

Instead of wiring up peering, gateways, and load balancers between services in different VPCs/accounts, Lattice gives a consistent layer to connect and apply access policies to your services. The tell is “simplify service-to-service connectivity and access control across VPCs/accounts.”
