A company runs a reporting application on a single EC2 instance. The reports are generated overnight and the application is idle for the rest of the day. Interruptions are acceptable provided the job finishes before 07:00. Which purchase option gives the lowest cost?
The workload is interruption-tolerant and runs in a window with slack in it, which is exactly the shape Spot is priced for — up to 90% below On-Demand. Reserved Instances and Savings Plans bill for a whole term regardless of use, so paying for 24 hours a day to run a job for three is more expensive than On-Demand, not less.

What the free tier does not include
Said before you sign up rather than after. Full-length timed mock exams, readiness tracking, weak-area practice and progress history are part of Pro — not because they are expensive to run, but because they are the things that only mean anything across many sessions, which is also when somebody knows whether the product is worth paying for.
