Multicloud architecture for augmenting security in clouds

Cloud computing is an important paradigm in this computing era which promises to reduce the initial capital investment as well as operational expenditures for hardware and software that are needed for an organization. The main obstacle that stands as a barrier for opting clouds, despite its benefits are its security challenges. Multicloud architecture is a solution that assures better security and performance at a nominal cost. There are different approaches used for storing and processing data in a multicloud environment, this paper is a study on the different multicloud architectures and their benefits and limitations.
