: Specification of how groups of pods are allowed to communicate with each other and other network endpoints.
The storage profile. Allows administrators to describe the "classes" of storage they offer, enabling dynamic provisioning on demand. Part 5: Cluster Resource Management & Scaling

A service with a None cluster IP. It allows you to interface directly with pods without load balancing, often used in StatefulSets. 26. Ingress
: Exposes the Service on a cluster-internal IP (default type).
Managing data and secrets requires precision.
Mastering these 50 concepts provides a rock-solid foundation for any DevOps engineer. Kubernetes is a vast ecosystem, but by breaking it down into these pillars—Architecture, Workloads, Networking, Storage, Security, and Scaling—you can navigate any cluster with confidence.
Allows dynamic provisioning. Instead of manually creating disks, you define a class ( fast-ssd , slow-hdd ). When a PVC asks for that class, the cloud provider auto-creates the disk.
Automatically scales the number of pods in a deployment or replica set based on observed CPU utilization or custom metric thresholds. 46. Vertical Pod Autoscaler (VPA)
The hard ceiling. The maximum amount of CPU and Memory a container is allowed to consume before being throttled or terminated. 35. Horizontal Pod Autoscaler (HPA)
