Actual exam question for Linux Foundation's CKA exam
Question #: 51
Topic #: 3
You are running a service that handles requests from multiple pods. How can you scale the service to handle increased traffic without impacting the service availability during the scaling process?

Suggested Answer:

See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Use a Deployment:
- Deploy the service using a Deployment with the desired number of replicas.
2. Define a Service:
- Create a Service that exposes the application to the outside world.
- Use a 'type: LoadBalancer' to distribute traffic across the pods.
3. Implement Horizontal Pod Autoscaler (HPA):
- Create an HPA that monitors the service's CPU usage.
- Configure the HPA to scale the Deployment based on the CPU utilization.

4. Test the Autoscaling: - Simulate increased traffic to the service. - Observe the HPA scaling the Deployment to meet the demand. 5. Monitor the Service: - Monitor the service's performance and ensure that it remains available and stable during scaling. 6. Adjust HPA Configuration: - Fine-tune the HPA configuration to optimize scaling based on specific performance needs.
