Hi@akhtar
As you mentioned, that you have moved to Bangalore because of your job and I totally agree with you that being a professional you do get not much of time to a classroom training ,so I suggest you to take online training course.Among them,I have enrolled for Edureka's Online course on AWS which covered almost all the important topics and gave some use cases for further use to implement.
For your reference, you can visit the institute site link given below for more details.
