Google’s Big Data Stats

YouTube: 60 hours of video uploaded every 60 seconds.
Google Search Index Size: 100,000,000 GB (and growing)
GMail Active Users: 350,000,000 (and growing)
Search Response Time: 0.25 seconds

These numbers are astonishing. Reliability, Available, Scalable & Performance are Google’s primary quality attributes.
Data – core business asset and few low hanging fruit, growth is faster than the ability to understand it, data capture is slower than the data getting generated, traditional BI tools can’t scale to capture it.
Google has innovated Map Reduce, HDFS, HBase are used by Google to solve for these requirements.
