hi

. I need a little help with a challenge from my AWS professor. He asked: 'How many practical ways are there to use Amazon Web Services (AWS)?' > The catch is, he claims there is a 'hidden' or unmentioned method beyond the standard ones
1-Pay-as-you-go (On-Demand)
2-Commitment-based pricing (Reserved Instances / Savings Plans)
3-Interruptible pricing (Spot)
4-Free tier usage
5-Volume-based tiered pricing (Use more, pay less per unit)

he says there is one other method that we are missing
