Cloud Computing security for efficient Big Data delivery

Διπλωματική εργασία--Πανεπιστήμιο Μακεδονίας, Θεσσαλονίκη, 2016.Big data nowadays are bound up indivisibly with the cloud computing technology. Many large organizations have already ventured to adopt cloud technology in order to manage large assets of structured and unstructured data. However, many small-scale organizations and companies would still refrain from such solutions. This research proposes a cloud computing security model by establishing security policies, implementing virtualization technology in their existing network, upgrading to cloud datacenters and processors and achieve a desirable information security level without a significant system slowdown
