## AI overview

A hands-on guide to encrypting traffic between Amazon ECS workloads with VPC encryption controls or Service Connect TLS. It covers activation on AWS Fargate and verification through VPC Flow Logs.

## Source excerpt

Learn how to encrypt traffic between Amazon ECS workloads using two native approaches: VPC encryption controls for network-layer encryption through the AWS Nitro System, and Service Connect TLS for application-layer encryption. A hands-on walkthrough shows how to activate encryption on AWS Fargate and verify it in VPC Flow Logs.
