What can a cloud practitioner use the aws total cost of ownership (tco) calculator for?

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.

AWS Calculators

AWS provides two calculators to calculate your estimated costs using two feature set calculators:

  • AWS Simple Monthly Calculator
    • Hosted on S3 (static website – e.g. calculator.s3.amazonaws.com/index.html)
    • You can configure a number of options to calculate your estimated total monthly cost of resources hosted on AWS
    • Not a comparison tool
  • AWS Total Cost of Ownership (TCO) Calculator
    • On-prem or in co-locations
    • Used to compare the cost for on-prem infrastructure versus hosted on AWS
    • Provides reports for export to present to C-level execs to make a business case to move to the cloud

These come up a lot in the exam so go into the AWS console and play with these
