Which tool is commonly used to orchestrate containers across multiple hosts according to the material?

• A. Docker Swarm
• B. Kubernetes
• C. Docker Desktop
• D. Hyper-V

Answer: (B)

Container orchestration across multiple hosts is about coordinating the deployment, scaling, networking, and health of containers across a cluster of machines so the system maintains a desired state automatically. Kubernetes is built specifically for this role, offering a robust control plane that schedules containers (as pods) across many nodes, manages service discovery and load balancing, supports rolling updates and rollbacks, handles auto-scaling, and ensures fault tolerance and proper storage integration. This makes it the standard choice for managing containerized apps at scale across multiple hosts. Docker Swarm can do orchestration too, but Kubernetes is the more widely adopted, feature-rich option. Docker Desktop is mainly for local development on a single machine, and Hyper-V is virtualization, not container orchestration.
