The one who knows all of these concepts and has these knowledge is not any more considered to be a back dev it is called devops engineer I suppose...

Was about to say that. As soon as I saw sharding, database replication, docker, and cloud computing, it seemed more like devops. I would say that makes back end developers more versatile but those things should be optional

if backend developer has to know all of these technologies, I doubt if any backend developer exists in this world :)

some of these things are beginner ,others are mid or advanced. some of those things are considered niche / specialization . in some of the categories you need to know at least one of them (e.g. programming languages) , in others you need to know all of them (e.g. Architectural Patterns ).
