Oracle Exam 1Z0-1109-23 Topic 1 Question 10 Discussion

The cluster option that is the best fit for ensuring reliable operations of Kubernetes at scale while minimizing the operational overhead of managing the worker node infrastructure is using OCI OKE virtual nodes to eliminate worker node infrastructure management. OKE is a fully managed service that allows you to run and manage your Kubernetes cluster on OCI. A Kubernetes cluster consists of a control plane and a set of worker nodes that run your containerized applications. OKE provides a highly available and secure control plane that is managed by Oracle, while you are responsible for managing the worker node infrastructure. However, OKE also supports virtual nodes, which are serverless compute resources that are automatically provisioned and scaled by OCI based on your application workload demands. Virtual nodes eliminate the need for managing worker node infrastructure, such as security patches, updates, scaling, etc. Virtual nodes also offer a serverless Kubernetes experience, where you can focus on developing and deploying your applications without worrying about the underlying infrastructure.
