Vertically scaling hardware to handle this data is not viable because it is expensive and difficult to manage. Distributed computing and horizontal scaling are good options, and frameworks such as Hadoop automatically cater to the fault tolerance, scaling, and distribution needs of such a system.

Analytics is all about data. A question that frequently arises is when does Hadoop become overkill? Typically, it is recommended that you use Hadoop for datasets of 1 TB and upwards.
