ALB to ECS Fargate End-to-End Encryption with AWS App Mesh?

Hi all,

I'm looking for guidance on achieving end-to-end encryption from an ALB to ECS Fargate containers. I found the following article, however, in discussion with some other folks, AWS App Mesh was also recommended.

https://aws.amazon.com/blogs/containers/maintaining-transport-layer-security-all-the-way-to-your-container-using-the-application-load-balancer-with-amazon-ecs-and-envoy/

When reading about AWS App Mesh, it only sounds like it handles end-to-end encryption between containerized applications. I'm not sure of the architecture when introducing the application load balancer.

I would appreciate any guidance or documentation you can provide.

Thank you!
