EKS Node Group

What it is: A managed group of worker nodes (EC2 instances) for an EKS cluster.

What it’s for:

• Provide compute capacity where pods run.
• Scale nodes automatically (managed node groups).

Key ideas:

• Nodes live in subnets (often across multiple AZs).
• Pods are scheduled onto nodes.

Exam cues:

• “EKS worker nodes in EC2” → node group.

Hard words:

• *worker node* /ˈwɝːkər noʊd/: node chạy workload
• *scheduled* /ˈskedʒuːld/: được xếp lịch chạy
