AKS with Azure Load Balancer - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is AKS in Azure?

AKS stands for Azure Kubernetes Service. It is a managed container orchestration service that simplifies deploying, managing, and scaling containerized applications using Kubernetes.

What role does Azure Load Balancer play in AKS?

Azure Load Balancer distributes incoming network traffic across multiple pods or nodes in AKS to ensure high availability and reliability of applications.

Explain the difference between Basic and Standard Azure Load Balancer in AKS.

Basic Load Balancer supports only a single availability set or virtual machine scale set and has limited features. Standard Load Balancer supports multiple availability zones, better performance, and more features like diagnostics and security.

How does AKS use LoadBalancer type services?

In AKS, when a service is defined with type LoadBalancer, Azure automatically provisions an Azure Load Balancer and assigns a public IP to route external traffic to the service pods.

What is the request flow when using AKS with Azure Load Balancer?

Client sends request to Azure Load Balancer's public IP → Load Balancer forwards request to healthy AKS nodes → Nodes route request to appropriate pods → Pods respond back through nodes and Load Balancer to client.

What does AKS stand for?

A Azure Key Storage

B Azure Knowledge Suite

C Azure Kernel System

D Azure Kubernetes Service

AKS means Azure Kubernetes Service, a managed Kubernetes container orchestration service.

Which Azure Load Balancer type supports multiple availability zones?

A Standard Load Balancer

B Classic Load Balancer

C Basic Load Balancer

D Internal Load Balancer

Standard Load Balancer supports multiple availability zones and advanced features.

In AKS, what happens when you create a service of type LoadBalancer?

A Service becomes internal only

B Pods are deleted automatically

C Azure provisions a Load Balancer and assigns a public IP

D No changes occur in Azure infrastructure

A LoadBalancer type service triggers Azure to create a Load Balancer with a public IP to route external traffic.

What is the main purpose of Azure Load Balancer in AKS?

A Store container images

B Distribute traffic to pods and nodes

C Manage Kubernetes clusters

D Monitor application logs

Azure Load Balancer distributes incoming traffic to ensure availability and scalability.

Which component routes traffic from Azure Load Balancer to pods inside AKS nodes?

A Kube-proxy

B Azure DNS

C Azure Blob Storage

D Azure Monitor

Kube-proxy inside nodes routes traffic from Load Balancer to the correct pods.

Describe the end-to-end request flow when a client accesses an application running on AKS with Azure Load Balancer.

Think about how traffic moves from outside the cloud to the container running your app.

Explain the differences and benefits of using Standard Azure Load Balancer over Basic in an AKS environment.

Consider availability, features, and production readiness.
