I still did not get kubernetes-engine and servless in GCP ,could you please try to help me for more understanding ?
Kubernetes is a container orchestration engine. When you deploy GKE in GCP you get a GKE cluster made up of Compute Engine Instances.
With serverless, the Compute Infrastructure is abstracted, and you pay for a per request and memory allocated to your Cloud Function, say.
It might help if you could elaborate on your question?
