====== Pod Networking Basics ======

**What it is:** How Pods communicate with each other and the outside network in Kubernetes/EKS.

**What it’s for:**
  * Enable service-to-service communication in a microservices architecture.
  * Control traffic using Kubernetes Services and network policies (when available).

**Key ideas:**
  * Pods typically have their own IP address.
  * A Kubernetes Service provides stable DNS/name and load balancing to Pods.
  * Security groups protect nodes/ENIs; in-cluster traffic control can use NetworkPolicy (implementation-dependent).

**Hard words:**
  * *DNS* /ˌdiː en ˈes/: hệ thống tên miền
  * *load balancing* /loʊd ˈbælənsiŋ/: cân bằng tải
  * *stable* /ˈsteɪbəl/: ổn định
  * *policy* /ˈpɑːləsi/: chính sách
