Hi,
Since you have mentioned you are an average student, I would advise to go for B.Sc. and these days B.Sc offers many different specialisations which might be helpful in order to job market and career. Considering the emerging demands in cloud computing, I would suggest to pursue cloud computing in B.Sc.
If it's not available then go for information technology. Also, BCA is another option which you have not mentioned here. After completion your B.Sc/BCA, you may grab couple of certifications on Cloud Computing and you will be all set.

If you wish to go for MBA. I will suggest you work hard to get a good college. Otherwise, MBA from any average college has no value. It will be difficult for you to carry out both the things together.
