I don't know wha your background is, but I would recommend to practice a lot and keep doing it.

If you were a software developer before (not required), then you are used of the do it mentality, the same applies for Cloud stuff.

By practicing a lot, you'll become more and more confident to do it and then you'll be happy that company will hire you because of your skills (better) than only because of any certification.

I have seen a few certified people being hired and fired afterward, let's do more effort for that certification (if you plan to get it) to only confirm your skills rather than defining it.

I myself practicing a lot, feel free to find out what I'm doing daily at: https://blog.numericaideas.com

While hoping this answer will help you somehow.

Let me know in you want more precision. Cheers!
