The network configuration for Amazon ECS Managed Instances. This specifies the VPC subnets and security groups that instances use for network connectivity. Amazon ECS Managed Instances support multiple network modes including awsvpc (instances receive ENIs for task isolation), host (instances share network namespace with tasks), and none (no external network connectivity), ensuring backward compatibility for migrating workloads from Fargate or Amazon EC2.
