с помощью AWS Elastic Beanstalk
Данное пошаговое руководство поможет вам запустить
демонстрационное приложение на PHP с помощью AWS Elastic Beanstalk (EB).
Помимо PHP, сервис EB поддерживает и другие языки программирования, в
том числе Java, .NET, Node.JS, Python, Ruby, Docker и Go, однако в
данном пособии будет рассмотрен пример с языком PHP (для других языков
процесс аналогичен). Сначала выполняется настройка приложения EB, а
затем настройка среды EB, в которой будет запущено приложение.
Вы уже знаете? AWS еще более упростила запуск интернет-приложений. Мгновенный запуск приложений с помощью Amazon Lightsail >>
