Moving the school office to the cloud

Lakeside School is made up. It plans to keep its records online instead of on one office computer. Staff will see records from home.

The head is excited. The caretaker asks: what if the internet goes down? Both are right. A good review looks at the gains and the limits, then decides.

Seven kinds of benefit

A solution can bring benefits. It may help staff get more done (productivity). It may keep services working (availability). It may please customers.

It may cut running costs or improve security. It may make records more accurate. It may help with disaster recovery: getting systems and data back after something goes badly wrong.
