Announcing additional Linux controls for Amazon ECS tasks on AWS Fargate

Introduction

An Amazon Elastic Container Service (Amazon ECS) task is a number of co-located containers that are scheduled on to AWS Fargate or an Amazon EC2 container instance. Containers use Linux namespaces to provide workload isolation—and with namespaces—even though containers are scheduled together in an Amazon ECS task, they’re still isolated from each other and from the host.

Today we’re excited to announce that customers can now tune Linux kernel parameters in ECS tasks on AWS Fargate. Tuning Linux kernel parameters can help customers optimize their network throughput when running containerized network proxies or achieve higher levels of workload resilience by terminating stale connections. This launch provides parity for ECS tasks launched on AWS Fargate and Amazon EC2 container instances.

Additionally with today’s launch, the process id (PID) namespace can now be shared by all containers in the same ECS task on AWS Fargate. Sharing the PID namespace between containers in the …
