Wise up, yes AWS credits basically do function seamlessly. Amazon credits are applied on your account accordingly and so your charges of billing should come down where you have credits to your accounts. It’s especially useful if you’re new to AWS or expanding and need to cut back on expenses. Similarly, for start-ups, AWS Activate credits free can be highly advantageous to fund those early costs which you do not have to pay from your own pocket, at least initially. Hope this helps!
