Question 1
What are the three fundamental drivers of cost in AWS?
Answer: Compute, storage, and outbound data transfer. These three categories determine the majority of your AWS bill across most services.
Question 2
What does AWS mean when it describes its pricing model as 'pay-as-you-go'?
Answer: You pay only for the resources you consume, with no upfront costs or long-term contracts required, allowing you to scale spending with actual usage.
Question 3
Which AWS pricing model offers up to 75% savings over On-Demand pricing in exchange for a 1- or 3-year commitment?
Answer: Reserved Instances (RIs). They offer significant discounts in exchange for committing to a specific instance type and term length.
Question 4
What type of EC2 pricing allows you to bid on unused AWS capacity and can be interrupted with a 2-minute warning?
Answer: Spot Instances. They offer up to 90% discount over On-Demand prices but can be terminated by AWS when capacity is needed elsewhere.
Question 5
What is the key difference between Compute Savings Plans and EC2 Instance Savings Plans?
Answer: Compute Savings Plans offer flexibility across any EC2 instance family, region, OS, and tenancy, as well as Fargate and Lambda. EC2 Instance Savings Plans are locked to a specific instance family and region but offer deeper discounts.
