I am a student and studying Computer Science. I am taking up Big Data Course this semester. As a part of curriculum, I am supposed to develop the Private Cloud using Ubuntu machines and other team needs to build up the authentication techniques for that private cloud. I am very new to bigdata and cloud even though i have basic understanding on concepts. I was going through the internet to see the resources on how to build cloud i came up with openstack which works best with ubuntu but before going any further into it i wanted to take the suggestions from stackoverflow community if they can guide me on the best tools and technology i can use to setup the private cloud. We now need to setup very small private cloud as a research project. Can anyone help me give me an idea on tools and technology please ? Appreciate the time.
