eBPF is a Linux kernel technology that allows programs to run safely in kernel space, enabling deep observability and security without code changes.

The four golden signals are latency, traffic, errors, and saturation — the key metrics every production service should monitor.

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.

An observability pipeline collects, transforms, routes, and filters telemetry data between sources and destinations for cost optimization.

Jenkins is an open-source automation server that automates building, testing, and deploying software through CI/CD pipelines.

A rolling update replaces application instances incrementally, ensuring continuous availability during the update process.

Crossplane extends Kubernetes to manage cloud infrastructure resources like databases and storage as native Kubernetes objects.

Immutable infrastructure means servers are never modified after deployment — they are replaced entirely with new versions.

Tekton is a Kubernetes-native CI/CD framework that defines pipelines as custom resources, running tasks as pods.
