Service Connect Elastic Container Service versus VPC Lattice

ECS Service Connect is specific for Amazon Elastic Container Service providing a simplified approach for service discovery, traffic resilience and observability out of the box. The customers will need to have networking knowledge of VPC peering for any cross-VPC deployments as ECS Service Connect does not handle any of the underlying network connectivity. ECS Service Connect does not use VPC Lattice under the hood. Whereas VPC Lattice is a way to automate connecting cross-account, cross-VPC microservices that are distributed across Kubernetes, native EC2/ASG and serverless environments eg Lambda, Fargate without needing any prior VPC networking experience. VPC Lattice provides fully automated VPC and inter-VPC networking without the need for sidecars, proxies. There is a roadmap item to integrate Amazon ECS with VPC Lattice with advanced features like authentication and authorization. At this time, you can configure ECS tasks in VPC Lattice as a service with a workaround and have an ALB/NLB as the target
