A LoadBalancer service type automatically provisions an external cloud load balancer (e.g. AWS ALB/NLB) and routes public traffic to the backend Pods.
ConfigMaps hold general configuration data as key-value pairs; Secrets store sensitive data like credentials and TLS keys with restricted access controls.
A Rolling Update spins up new Pods and waits for their readiness probes to succeed before terminating old Pods, ensuring uninterrupted traffic handling.
Liveness detects deadlocks and restarts the container; Readiness ensures dependencies are initialized before routing traffic to the Pod.
kubelet communicates with the API server to manage local node containers and report health status.
kube-scheduler evaluates node resource requests and constraints to assign unscheduled Pods.
The HPA scales Pod replica counts dynamically based on target metrics.
