 Understanding the Requirements:

The customer needs an open-source container orchestration system.

It must support cloud-native applications.

It should provide support for containers with persistent storage.

 Platform Options:

Hortonworks Data Platform (A): This is primarily focused on big data and Hadoop-based applications, not on container orchestration.

Hadoop (B): Hadoop is an open-source framework for distributed storage and processing of big data, not a container orchestration system.

OpenStack Neutron (C): Neutron is the networking component of OpenStack, which is not designed for container orchestration.

Kubernetes (D): Kubernetes is an open-source container orchestration platform that supports cloud-native applications and persistent storage.

 Why Kubernetes (D) is the Best Fit:

Cloud-Native Support: Kubernetes is designed to manage containerized applications across clusters of hosts, providing deployment, scaling, and operations of application containers.

Persistent Storage: Kubernetes supports persistent storage through Persistent Volumes (PVs) and Persistent Volume Claims (PVCs), integrating with various storage backends.

Community and Ecosystem: Kubernetes has a vast open-source community and ecosystem, offering extensive support and resources for cloud-native applications.
