Which open source orchestration platform developed by Google manages containerized applications and microservices, enabling deployment patterns and failover?

• A. OpenShift
• B. Kubernetes
• C. Docker
• D. Mesos

Answer: (B)

Container orchestration automates deployment, scaling, and health management of containerized applications and microservices. Kubernetes, an open-source platform originally developed by Google, fits this role by coordinating containers across a cluster. It uses declarative configuration to describe the desired state and controllers to continually reconcile actual state with that goal. Kubernetes supports deployment patterns like rolling updates (gradual shifts from one version to another) and canary deployments, and it manages multiple replicas of pods to ensure reliability. For failover, it monitors health, restarts unhealthy containers, and reschedules pods to healthy nodes, with services routing traffic as needed. This combination makes Kubernetes the best fit for managing containerized workloads at scale. OpenShift is Kubernetes-based but developed by Red Hat; Docker is a container runtime, not an orchestrator; Mesos is a different cluster management system.
