[Udemy] Kubernetes Certified Administrator by School of Devops + bonus

Курс для подготовки к экзамену Kubernetes Certified Administrator от School of Devops

Описание:
Этот курс знакомит вас с моими знаниями в области построения и управления инфраструктурой, опытом помощи компаниям в их путешествии и более 300 корпоративных тренингов. Это хорошо проработанная программа, и я пробовал много вариантов приложений с разными потоками, брал отзывы и многократно повторял. Это одна из причин, почему нам потребовалось более 4 месяцев, чтобы даже запустить курс в его первой форме. Мы также начали внедрять некоторые новые и полезные методы, в том числе «стеклянную доску», «карты разума», чтобы лучше объяснить концепции и сделать вещи проще. Я и моя команда хотим сделать эту программу лучшей в мире и постоянно работаем над этим.
