Renaissance Italy created an explosion of new ideas across art, science and culture, but the biggest idea to come from that era was the idea of the modern bank. By creating an independent entity to hold and protect customer assets, modern banking helped lay the foundation for modern capitalism, and all the wealth that it has created. The beautiful thing about banks is that when you put your money in, you still own it. You can withdraw it at any time, usually in a matter of minutes. If only cloud computing could work this way.
