Kubernetes Architecture for AI Workloads

Understanding Kubernetes architecture is essential to effectively deploy AI workloads. The core components include:
Node: A machine (virtual or physical) running containerized applications.
Cluster: A set of nodes grouped to optimize workload management.
Pod: The smallest deployable unit in Kubernetes; may contain multiple containers.
Controller: Manages and ensures the desired number of pods are operational.
Service: Defines a logical set of pods, establishing a policy for accessing them.

Learning Objectives
