The RED method monitors three key metrics for request-driven services: Rate, Errors, and Duration.

The USE method monitors infrastructure resources by tracking Utilization, Saturation, and Errors for every resource.

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

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

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

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

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

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

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

An IDP is a self-service layer that abstracts infrastructure complexity, enabling developers to deploy and manage applications independently.
