Writing SOP to convince the academic director is entirely different from the one we help students write for Visa purpose. I believe its more than your feelings what makes an SOP a success. Yes, it should have facts and reasons to support your dream to purse particular course at chosen University or a college.
From admission directors' perspective i need to see your opted course relevancy to your previous studies, which is a must. What all core units you have studied in past to support your understanding in Cloud Computing ?
Check for course eligibility criteria first before applying for offer.
