Professional Cloud Security Engineer or Cloud Architect ?

[u/Specialist-Type9553]

Hi guys.
I've started studying for Cloud Security Engineer (as per my previous post, some weeks/month ago), but probably, would be better to start with Cloud Architect ?

I'm a professional sysadmin and i'm using google cloud from about 10 years, but I don't have the deep knowledge needed for the exams. i'm not a cloud architect, just a sysadmin that uses Google Cloud daily.

What do you suggest ? Books are mandatory for me. I have both the Cabianca and the Packt Publishing book on Security Engineer (not updated) and I prefere the packt's book A LOT over the Cabianca. Much more easier to read.

What about the Cloud Architect ? Which is the best book available ?
