Проблема старения населения на сегодняшний день особо остро стоит перед развитыми странами. Улучшение качества жизни и медицинского обслуживания приводит к увеличению продолжительности жизни с одной стороны, а также серьезным трудностям, таким как уве личение спроса на медицинское обслуживание, высокие риски развития хронических болезней, повышение затрат на пенсии и здравоохранение, с другой. В такой ситуации ИКТ рассматри вается как инновационный подход к решению подобных проблем. С развитием концепций дис танционного медицинского обслуживания появляется все больше и больше частных сервисов и продуктов, которые, при использовании СОА, могут работать вместе для получения эффекта синергии. В данной статье на примере диабета разрабатывается система дистанционного мониторинга состояния здоровья пациента на основе сервис-ориентированной архитектуры, управляемой событиями. Вместе с детальным описанием архитектуры системы и ее преиму ществ в статье дается обзор рынка дистанционного медицинского обслуживания, его барьеров и потенциала развития.
