Which technology is commonly used to efficiently manage device resources in shared environments?

The chosen answer is correct because Kubernetes is a powerful platform specifically designed for container orchestration in shared environments, such as those found in cloud computing and microservices architectures. It enables efficient management of computing resources by automating the deployment, scaling, and operation of application containers across clusters of hosts. This allows organizations to fully utilize their available computing resources while ensuring high availability and fault tolerance.

Kubernetes performs several crucial functions, including load balancing, service discovery, and resource allocation, which are essential in environments where multiple applications and services run concurrently. By managing these resources effectively, Kubernetes can help minimize costs and improve performance in shared settings.

In contrast, while TensorFlow primarily focuses on model training and machine learning tasks, it does not specifically address resource management in shared environments. Docker, on the other hand, is focused on containerization and application deployment, serving as a foundation that Kubernetes builds upon for orchestration. Apache Spark is designed for large-scale data processing and analytics, rather than managing device resources effectively in shared environments. This distinction reinforces why Kubernetes is the more appropriate technology for managing device resources within such contexts.
