In this short series, I outline the notes that I took while preparing for the AWS Cloud Practitioner exam.
These are my personal notes that I have made while working through the A Cloud Guru exam practitioner course. They are in no way official notes from AWS.
I would advise you that if you do use my notes to help you revise for this exam, that you use them as a supplement to the most recent information in the White Papers, Exam Guide and go over your knowledge with practice exam papers.

Understand The Fundamentals Of Pricing
- Three fundamental drivers of cost with AWS:
- Compute
- Storage
- And Data Outbound
Start early with cost optimization
- Put cost controls in place before your environment grows
- Managing cost effectively from the start ensures that managing cloud investments doesn’t become an obstruction as you grow and scale
Maximize the power of flexibility
- AWS services are priced independently and transparently
- By using PAYG, it allows you to just focus on your environment
- Don’t pay for them when they’re not running
Use the right pricing model for the job
- AWS offers several pricing models depending on product. These include:
- On Demand
- Dedicated Instances
- Spot Instances
- Reservations
