Master Kubernetes networking — Services, Ingress, DNS, CNI plugins, and Network Policies that control how traffic flows inside and into your cluster.
Written guides that show you how to apply this concept in real projects.
Progressive delivery lets you ship to 5% of users first and roll back in 30 seconds if something breaks — here is how to implement canary deployments with Argo Rollouts and Flagger on Kubernetes.
Key words used in this concept — explained simply, no jargon.
A Kubernetes mechanism for partitioning cluster resources into isolated virtual segments. Namespaces allow multiple teams, projects, or environments to share the same physical cluster while maintaining logical separation of workloads, access controls, and resource quotas. They do not provide network isolation by themselves — that requires Network Policies.
Kubernetes Networking and Traffic Management covers a variety of key topic guides, including: Configuring Ingress Controllers with NGINX for Production Traffic, Debugging Kubernetes Networking with kubectl and CNI Plugins, Kubernetes Network Policies for Pod-Level Traffic Control, Implementing Kubernetes Deployment Strategies - Rolling, Blue-Green, and Canary, Configuring Kubernetes Resource Requests, Limits, and QoS Classes, Understanding Kubernetes Service Types — ClusterIP, NodePort, and LoadBalancer, Implementing Kubernetes Pod Security Standards and securityContext, Monitoring Kubernetes with Prometheus and Grafana. Master Kubernetes networking — Services, Ingress, DNS, CNI plugins, and Network Policies that control how traffic flows inside and into your cluster.
Kubernetes Networking and Traffic Management is a core learning conceptual pillar mapped within the kubernetes engineering hub of the DevOps Network.

Kubernetes clusters routinely waste 40-70% of provisioned resources. Here is the complete playbook for cutting cloud spend without touching your SLOs.
An API object that manages external HTTP and HTTPS access to services inside a cluster. Ingress sits in front of multiple services and acts as a smart router — directing traffic based on hostnames, URL paths, or headers without exposing each service directly to the internet.
