Description: A host cluster in virtualization refers to a set of physical servers that work together to provide computing resources to virtual machines. This approach allows for more efficient resource management, as hosts can share workloads, balance CPU, memory, and storage usage, and offer high availability. Clusters are fundamental in virtualization environments, enabling the creation of a scalable and flexible environment where virtual machines can move between different hosts without interruptions. Additionally, clusters facilitate the implementation of disaster recovery policies and performance optimization by allowing administrators to distribute workloads more effectively. In virtualization platforms, clusters can be configured with different levels of redundancy and fault tolerance, ensuring that services remain available even if one or more hosts fail. This architecture not only enhances operational efficiency but also provides a robust framework for resource management in complex enterprise environments.
