As a Junior Developer, Should we learn Cloud Computing Services[Amazon etc.]

I'm trying to build blog for personal use and learn Spring Framework. At the end of development, I started to learn some basics of AWS and discovered it's HUUUUUUGE area to be expertise. Masters called DevOps Engineer. For me(with this hobby project) it's just extra load and demotivates me. Yes, I know some basics and capabilities of cloud services but i think it's destroys all fun of coding process.

My question is; is it must to learn Cloud Computing Services for Code-Oriented Developer.

Code-Oriented: The guy who passionate about develop softwares.
