7. © 2004 IBM Corporation 7 Текущая ситуация: автоматизация функций Исторические ограничение: У «монолитных» приложений невозможно изменить сферу применения В результате специализированной интеграции образуются связи, которые трудно как изменять, так и поддерживать Отсутствие единых стандартов ограничивает возможность обеспечения подлинного взаимодействия Маркетинг Партнеры Web Партнеры Продажи Партнеры

8. © 2004 IBM Corporation 8 Маркетинг Партнеры Web Партнеры Продажи Партнеры Будущее: горизонтальная интеграция процессов Усовершенствования, которые делают горизонтальную интеграцию возможной: Основные поставщики согласовали единые стандарты создания сервисов и обеспечения их взаимосвязи Появилась инфраструктура, которая поддерживает индивидуальные, практически не связанные с другими сервисы Появились механизмы, позволяющие интегрировать существующие системы Имеются возможности для автоматизации и виртуализация системных ресурсов Заказчик/ поставщик

9. © 2004 IBM Corporation 9 Для горизонтальных бизнес-процессов необходима технологическая инфраструктура нового поколения Горизонтальный процесс Упрощение IT-инфраструктуры Автоматизация/виртуализация Надежность Безопасность Оптимизация Готовность к работе Настройка в соответствии с едиными принципами Управление в области бизнес- услуг Виртуализация ресурсов – серверов, хранилищ данных, распределенных систем/сетей Бизнес-моделирование Трансформация процессов Интеграция приложений и информации Доступ и взаимодействие Управление бизнес-процессами Интеграция Управление инфраструктурой Гибкость бизнеса

10. © 2004 IBM Corporation 10 Сервисно-ориентированная архитектура (SOA) является ключевым фактором Что такое SOA? SOA обеспечивает гибкость во взаимодействии приложений и ресурсов за счет: Представления каждого приложения или ресурса в виде сервиса со стандартным интерфейсом Обеспечения обмена структурированной информацией. Почему этот так важно? SOA помогает обеспечить гибкость с точки зрения технологий. Все больше компаний и специалистов признают принцип SOA в качестве основного похода к интеграции и формированию единой структуры взаимодействующих приложений.

29. © 2004 IBM Corporation 29 Видимые трудности на пути внедрения СОА  Привычный клиент-серверный базоцентрический подход  WS * - спецификации находятся в процессе выработки. Web Services – единственный на данный момент действующий способ реализации COA  Технология Web Services сама по себе имеет недостатки, являющиеся обратной стороной интероперабельности. Все будет хорошо!

30. © 2004 IBM Corporation 30 От единой базы данных к единой шине  Базоцентрический подход – Одно приложение размещает в общей базе документ, другое приложение опрашивает базу считывает документ  Среда, основанная на обмене сообщениями – приложение хранит свое состояние в своей базе, формирует документ на основе информации из базы, посылает его как сообщение другому приложению.

31. © 2004 IBM Corporation 31 WS * - спецификации находятся в процессе выработки  J2EE – пример пути, который будет пройден WS*-парадигмой  Нижележащие слои обеспечивают недостающую функциональность  Реальные проекты уже стартуют
