Description: Affinity Rules are guidelines that determine how virtual machines (VMs) are distributed among hosts in a virtualized environment. These rules are essential for optimizing performance and resource availability in virtualization scenarios. By establishing affinities, it is possible to specify that certain virtual machines run on specific hosts or are avoided on others, allowing for more efficient workload management. For example, rules can be created to ensure that VMs requiring high levels of resources are distributed across different hosts to prevent overloading a single server. Additionally, affinity rules can help maintain security and compliance by ensuring that VMs handling sensitive data do not run on the same host as less secure VMs. In summary, Affinity Rules are key tools for managing virtualized environments, allowing for better planning and utilization of available resources.
