Guys I want to do an MBA , (current exp 4yrs(in TCS). Can you suggest good MBA online course and platform from where I should get it?

Why online and why not in person? Try CAT you will be eligible for Executive programs. Or you can try International Uni executive online programs but they do tend to be costly. With MBA the quality of the Uni matters alot. Infact it's the brand that matters and opens doors. So don't skim on it cause it does bite you back most often.
