====== 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 [[pod|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
