AWS Cloud Practitioner: EC2 Pricing

AWS Cloud Practitioner: EC2 Pricing

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 PapersExam Guide and go over your knowledge with practice exam papers.
