Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider.

Cloud computing enables big data to control and distribute the stored data in a suitable way. It also provides security to big data through Hadoop. The main idea of big data is to accumulate, handle, visualize, and evaluate the huge amount of data, which is achieved by collaboration with cloud computing.

A subscription-based delivery model, cloud computing provides the scalability, fast delivery and IT efficiencies required for effective big data analytics. Because it removes many physical and financial barriers to aligning IT needs with evolving business goals, it is appealing to organizations of all sizes.
