Anyone knows about AWS (Amazon Web Service), what is the plus point compare to normal web ?

Is it:

  • AI (Artificial Intelligence)
  • IoT (Internet of Things)

I also have a question what is the difference between Hadoop Apache and the normal Apache in most web hosting?

Thanks in advance.

It is none of those things. Amazon have lots of servers, in some cases it's easier/cheaper/more-reliable to use theirs than have your own.

If you don't know the difference between Hadoop and Apache HTTPD, you don't need Hadoop.
