⚠️ EC2 instances running in your AWS account. ECS Cluster Auto Scaling does not cover all aspects of operating virtual machines (e.g. rolling update to update AMI).

⚠️ EC2 instances running in your AWS account, but Managed Node Group + Cluster Autoscaler automate most operations tasks.

✅ Managed Node Groups and Cluster Autoscaler scale the cluster capacity up and down automatically.

✅ ENI and Security Group per task/container.
