Description: A host group is a collection of hosts that can be managed together in a cloud environment. In the context of cloud computing, a host group allows users to organize and manage instances more efficiently. Each host group consists of instances that share similar characteristics, such as hardware type, geographical location, and network configurations. This facilitates the implementation of scaling policies, resource management, and performance optimization. Additionally, host groups enable administrators to apply configurations and updates uniformly across all instances within the group, reducing operational complexity. The ability to group hosts is also essential for capacity planning and disaster recovery, as it allows organizations to maintain tighter control over their cloud resources. In summary, host groups are a key tool for efficient instance management in cloud environments, providing a structure that enhances organization and control of resources in a dynamic setting.
