• Конечный автомат — абстрактный автомат без выходного
потока, число возможных состояний которого конечно.
Результат работы автомата определяется по его конечному
состоянию
• http://ru.wikipedia.org/wiki/Конечный_автомат
• Finite state machine (FSM)
• В UCS конечными автоматами являются
• Физические компоненты (шасси, модули ввода-вывода, серверы)
• Логические компоненты (LAN cloud, политики)
• Рабочие процессы (загрузка, обновления ПО, резервное
копирование)
• Ценный инструмент при расследовании проблем
