Leading Drupal deployment on large scale Cloud based systems (English)

Have you ever had a project that is much sophisticated than just a simple web page, an application that requires more than one web server or a separate database server.
How to manage your deployment strategy, plan the scope of works. Mentor and train your team.
In my talk I'll try answer those questions (and others) providing examples from my personal experience. This talk is not aiming to be highly technical or I'd better say too geeky, it will be about people involved in your team or you are engaged with over the project's life time.
It is assumed that you have some knowledge of cloud based technologies.
