Part of Kubernetes Networking and Traffic Management
Configuring Ingress Controllers with NGINX for Production Traffic
Configure NGINX Ingress Controllers on Kubernetes to route production HTTP and HTTPS traffic with SSL termination, path routing, and rate limiting.
Kubernetes Network Policies for Pod-Level Traffic Control
By default, every pod in a Kubernetes cluster can talk to every other pod — regardless of namespace, team, or sensitivity. Network Policies are Kubernetes firewall rules that restrict this. They define which pods are allowed to send traffic to which other pods, and which external IPs can reach your services. Without them, a compromised frontend pod can directly connect to your production database.
Implementing Kubernetes Deployment Strategies - Rolling, Blue-Green, and Canary
Learn how to deploy new application versions to Kubernetes with zero downtime using rolling updates, blue-green switching, and canary traffic splitting.
