A Pod Disruption Budget limits the number of pods that can be voluntarily disrupted at once, ensuring minimum availability during maintenance.

Linkerd is a lightweight, CNCF-graduated service mesh for Kubernetes providing observability, security, and reliability with minimal complexity.

The sidecar pattern deploys a helper container alongside the main application container in a pod, extending functionality without code changes.

A Kubernetes Network Policy controls traffic flow between pods at the network level, acting as a firewall for your cluster.

A Kubernetes CRD extends the Kubernetes API by defining new custom resource types managed like native Kubernetes objects.

A Kubernetes Secret stores sensitive data like passwords, tokens, and certificates, keeping it separate from application code.

A Kubernetes ConfigMap stores non-confidential configuration data as key-value pairs for consumption by pods and containers.

Kubernetes HPA automatically scales the number of pod replicas based on observed CPU, memory, or custom metrics to match demand.

A Kubernetes DaemonSet ensures a copy of a specific pod runs on every node, ideal for logging, monitoring, and system-level agents.

A Kubernetes StatefulSet is a controller for stateful applications requiring stable network identities, persistent storage, and ordered deployment.
