AWS - EKS

You need to deploy a stateless web service on EKS that scales automatically between 3 and 10 pods based on CPU utilization. Which Kubernetes resources should you define in your deployment manifests to achieve this?

AA DaemonSet to run one pod per node and a ClusterAutoscaler to manage node count

BA StatefulSet with replicas set to 10 and a PodDisruptionBudget to limit scaling

CA Deployment with replicas set to 3 and a HorizontalPodAutoscaler targeting CPU usage with minReplicas 3 and maxReplicas 10

DA Deployment with replicas set to 10 and manual scaling using kubectl scale commands

Step-by-Step Solution

Solution:

Step 1: Use Deployment for stateless apps
Deployments manage stateless pods and support rolling updates.
Step 2: Set initial replicas
Set replicas to the minimum desired pods (3) to ensure baseline availability.
Step 3: Configure HorizontalPodAutoscaler (HPA)
HPA automatically scales pods between minReplicas and maxReplicas based on CPU metrics.
Final Answer:
A Deployment with replicas set to 3 and a HorizontalPodAutoscaler targeting CPU usage with minReplicas 3 and maxReplicas 10 -> Option C
Quick Check:
Deployment + HPA for autoscaling [OK]

Quick Trick: Use Deployment + HPA for CPU-based autoscaling [OK]

Common Mistakes:

Using StatefulSet for stateless apps
Relying on manual scaling instead of HPA
Using DaemonSet which runs one pod per node
