Hadoop Benefits - Kapil Sharma

Hadoop Benefits:

Every day approx 3 exabytes (2.5×1018) of data were created globally.

Benefits: If analysed than they reveal patterns, trends, and associations, especially relating to human behaviour and interactions.

Low cost: Hadoop is open-source framework. So its free. 

Computing power: It has distributed computing model which quickly process very large data volumes. The more nodes(computing) you use the more processing power your hadoop setup going to have.

Scalability: Easily increase your hadoop system simply by adding more nodes. Less IT administration is required.

Storage flexibility: Hadoop includes unstructured data like text, images and videos in a single go. Users can store as much data as they want and decide how to use it later period.

Inherent data protection and self-healing capabilities: Data and application processing are protected against hardware failure. If a system(node) goes down, jobs are auto redirected to other systems to make sure the distributed computing does not leads failure. And it auto stores multiple data copies of input data.
