A company runs a web service on Amazon EKS using a Deployment and a Service of type LoadBalancer. The team wants to deploy a new version to a small subset of pods and route a small percentage of live traffic to them for validation before rolling out to all pods. Which approach should the team use?

Use the kubectl rollout restart command to force all pods to restart with the new image

Create a second Deployment with the new version and use a service mesh or ingress controller to split traffic by weight

Update the Deployment's image and use the default rolling update strategy

Delete the existing Deployment and create a new one with the new image

A company currently deploys application updates to EC2 instances by running a script that stops the application, copies new files, and restarts the application. They are experiencing configuration drift and inconsistent environments across instances. The team wants to adopt a more reliable deployment pattern that ensures every instance is identical and can be easily rolled back. Which approach should the team implement?

Continue using the script but add more configuration management steps

Use AWS CodeDeploy to perform an in-place deployment with a custom script

Use AWS Systems Manager Run Command to apply patches to all instances

Build a new Amazon Machine Image (AMI) for each release and launch new instances from it

A team manages a Lambda function that processes financial transactions. They want to deploy a new version using a canary strategy. The team needs to monitor error rates and latency for 10 minutes before shifting all traffic. If the error rate exceeds 1%, the deployment should automatically roll back. Which approach should the team use?

Use a Lambda alias with a routing configuration to shift 10% of traffic, then manually monitor CloudWatch metrics and update the alias after 10 minutes

Use AWS CodeDeploy with a canary traffic-shifting configuration and a CloudWatch alarm for automatic rollback

Create a new Lambda function with the new code and update the event source mapping to point to it

Publish a new version and update the function's $LATEST alias to point to it
