What will be left in the server room?

Many organizations use cloud services or move equipment to a data center. What makes sense to leave in the server room and what is the best way to organize the protection of the office network perimeter in such a situation? Once upon a time, everything was on the server.

There is a summary at the end of the article. When working with changes, no matter what exactly they concern - be it the company's development strategy, motivation systems, organizational structure or code design rules - there is always one key link: ideas.
