Knowledge

Network

  • URL maps specify direct requests to particular services.
  • Routes are used to specify paths to destination IP addresses outside a subnet.
  • Firewall rules control the flow of traffic on a network.
  • Traces are used to understand performance characteristics of services in a distributed system.

Load Balancer / Proxy: (Internal) HTTP(S) Load Balancing SSL Proxy TCP Proxy Network TCP/UDP Load Balancing

GKE Cluster

  • Single zone: single zone, sinle master
  • Multi zone: multiple zones, single master
  • Regional: multiple zones, multiple master

Kubernetes Services:

  • Headless service is a service without a cluster IP that allows direct communication to individual pods via DNS records, commonly used for stateful applications like databases where each pod represents a unique instance.
  • ClusterIP in Kubernetes is an internal virtual IP address assigned to a service for accessing pods within the cluster.
  • PersistentVolume in Kubernetes is a storage abstraction that provides durable storage resources, decoupled from pods, allowing them to access and persist data across pod restarts or rescheduling events.
  • NodePort in Kubernetes is a service type that exposes an application externally by allocating a static port on each node in the cluster, allowing access to the service from outside the cluster through the node's IP address and the allocated port.
  • LoadBalancer in Kubernetes is a service type that provisions an external load balancer (typically from a cloud provider) to distribute incoming traffic across multiple pods in a service, enabling high availability and scalability of the application.
