Trade capital expense (CAPEX) for variable/operating expense (OPEX) 2. Benefit from massive economies of scale 3. Stop guessing about capacity (Elasticity) 4. Increase speed and agility 5. Stop spending money running and maintaining data centers (No maintenance of hardware) 6. Go global in minutes https://www.youtube.com/watch?v=yzoiTsku44U  Week 1 Goals 1. Sign up for AWS Academy 2.
