In this lesson, you will learn the key concepts that give cloud infrastructure its edge.

AWS trades capital expenses for ongoing variable expenses, mitigating a huge amount of financial risk when starting a new business.

When you lose traffic, you eat the costs of both your servers and your reduced revenue. When you get an unexpected spike in traffic, you can lose a huge amount of potential revenue if your servers can't handle the traffic. Elasticity mitigates these risks by giving you the ability to acquire and release resources on demand.

The advantages clearly explain why the cloud market has become a $100 billion dollar industry.
