@TuncerYukler My advice would be as long as you achieve the certification you are after i.e. AWS Certified Architect or others which are top of mind at the present.
So if you do achieve for example AWS Certified Architect, and can formally pass the required examination, then you would be entitled to provide the evidence i.e. certification and the associated study time in preparation to pass the examination etc. The evidence would be in the form of an AWS Digital Certificate and links etc.
There are many more such sites such as Cybrary.it, or if your organisation provides links to O'Reilly or Udemy, you may find these useful in preparation for those examinations etc.
My advice is go discover, learn, develop and keep achieving, it becomes an ongoing drive for continuous learning.
