Reactive & Distributed – Архитектура современного приложения

SECR 2018
Орхан Гасымов
Digital Transformation Architect, GlobalLogic

За последние годы требования к современным приложениям возросли от гигабайтов данных до терабайтов, от тысяч запросов в секунду до миллионов, от секунд на время отклика до миллисекунд, и этот список можно продолжать. До сих пор большинство подобных задач решались применением микросервисной архитектуры, однако, что дальше? Какой следующий подход применить там, где микросервисы не справляются? В этом докладе мы поговорим о современных подходах к разработке приложений с реактивной и распределенной архитектурой.
