Please take a moment to review if you are looking for a full cloud (security) training, or just an overview of how that would look like.
This course is intended to be the latter, though lots of participants find more value than that.
If this is not what you are looking for, just ask for a refund, no bad feelings.
But please only give low ratings to this course if you find it unclear. Better even: make specific improvement suggestions.
This course covers CCSK version 4 as it was updated late 2017.
You will also find a lot more explanation at my YouTube channel: ClubCloudComputing. Just go to YouTube and search for “ClubCloudComputing”.
