Description: XenServer High Availability ensures that virtual machines remain operational even if a host fails. This system is designed to minimize downtime and ensure that critical services continue to function without interruptions. High Availability is achieved through the implementation of a cluster of servers, where virtual machines can be automatically migrated to other hosts in the event that one of them experiences a failure. This process is carried out transparently to users, meaning that no manual intervention is required to restore services. The main features of High Availability include constant monitoring of host status, the ability to automatically restart virtual machines on an alternative host, and integration with management tools that facilitate the administration of the virtual environment. The relevance of this functionality lies in its ability to provide a resilient IT environment, where businesses can operate with confidence, knowing that their applications and data are protected against hardware failures. In a world where continuous availability is crucial, High Availability solutions become essential for organizations that rely on virtual infrastructure for their daily operations.
