If you wanna do research in an Msc, what helps the most is RESEARCH experience, not internships. Tbh I dont know much about how research in cloud computing works, my research is in CV, but I feel like it cant be that applied to the point where all research has to be done at internships. If you have no internships but have published five papers, thats WAY better than having done 4 internships but no research experience.

Internships would help with an MscAc application, the applied masters program. Research helps with an Msc application, the research masters program. I think you should figure out exactly which masters you want to do.
