Choosing between Cambridge University and Acharya University for a B Tech in Information Systems really depends on your personal situation. If you're thinking about studying in the UK and possibly staying there, Cambridge is a great choice, as long as you can afford the fees and living expenses. Just remember that the weather can be quite challenging, and the culture might take some getting used to.
On the other hand, Acharya University seems to be a private institution in Madhya Pradesh, which might be more convenient if you prefer staying closer to home. Make sure to check whether it has AICTE or UGC recognition, and take a look at the syllabus to see if it fits your needs.
Hope this helps you decide.
