What Amazon Fargate is

Amazon Fargate is a new launch type for Amazon ECS and Amazon EKS (Elastic Kubernetes Service)-managed orchestration services for Docker containers on AWS. With the Fargate launch type, the infrastructure is fully provisioned by Fargate. It is serverless, and no EC2 instances are exposed to the user. Docker containers are defined as container definitions within a task definition. A service implements the task definition to run one or more tasks. Each task is associated with an ENI. If the auto-assignment of the public IP at the task level is enabled, a public IP on which an external client may access a task is automatically assigned to a task. Tasks communicate with each other over a private IP.
