Some innovations in the previous century changed how data can be used. Had it not been for these innovations, we would have faced the issue of finding a needle in the haystack, while dealing with big data. Both these innovations have emerged from Google. The first innovation is Hadoop. It allows the storage of unlimited data in multiple locations on economical servers — this is what we call the Cloud. The second innovation is crawling or searching the data haystacks in a very short time. The credit for web crawling goes to Sergey Brin, the co-founder of Google.
