Я написал функцию Azure, которая работает как микро-шлюз для двух моих систем API.Этот шлюз проверяет подлинность трафика на сервере аутентификации, вызывает один из бэкэндов API и, наконец, сообщает результат серверу аутентификации.
Я попытался загрузить это приложение-функцию локально с помощью JMeter - запустил загрузку 100 одновременно работающих пользователей, обращающихся к различным URL-адресам обоих бэкэнд-API.Все выглядит хорошо.Когда я запускал netstat во время нагрузочного теста на моем локальном компьютере, func.exe показывает «пару» УСТАНОВЛЕННЫХ подключений к каждому из бэкэндов и группу для 127.0.0.1:7071 (моя функция запускается на порту 7071 локально)
Когда я развертываю приложение в Azure и запускаю ту же нагрузку, оно отлично работает в течение нескольких секунд, а затем начинает выдавать много SocketException в течение нескольких секунд.Это повторяется.
Вот мой псевдокод.Пожалуйста, дайте мне знать, что я делаю неправильно.
