In many SMEs, IT has grown with them. The local network in the offices was connected via Ethernet cables. A switch connected the connected computers to the Internet and the local server. When the amount of data grew, a network storage unit was added. This is still used today as a central repository for various company documents and serves as storage for the local server. When the Microsoft 365 license came along and with it the cloud, the question arose as to whether it was still appropriate to store data on a network storage device.
