Due to the issues raised by its volume, velocity and variety, Big Data requires new technology solutions. Currently leading the field is an open-source project from Apache called Hadoop. This is developing a software library for reliable, scalable, distributed computing systems capable of handling the Big Data deluge, and provides the first viable platform for Big Data analytics. Hadoop is already used by most Big Data pioneers. For example, LinkedIn currently uses Hadoop to generate over 100 billion personalized recommendations every week.
What Hadoop does is to distribute the storage and processing of large data sets across groups or “clusters” of server computers using a simple programming model. The number of servers in a cluster can also be scaled easily as requirements dictate, from maybe 50 machines to perhaps 2000 or more. Whereas traditional large-scale computing solutions rely on expensive server hardware with a high fault tolerance, Hadoop detects and compensates for hardware failures or other system problems at the application level. This allows a high level of service continuity to be delivered from clusters of individual server computers, each of which may be prone to failure. Processing vast quantities of data across large, lower-cost distributed computing infrastructures therefore becomes a viable proposition. READ REST OF STORY

Description: When Spotify, the digital music company of the moment, announced this week an exclusive deal with Led Zeppelin and free access on mobile devices, it also reported impressive numbers. Its listeners have streamed 4.5 billion hours of music this year, and it has paid more than $1 billion in music royalties since its founding.

Yet even as they have grown, streaming companies have encountered a stubborn problem: Music lovers will consume large amounts of music as long as it is free, but getting them to pay a monthly subscription has proved much more difficult.
Pandora, the only publicly traded streaming company, delivers about 1.5 billion hours of music each month to more than 70 million users, but only about three million of them pay. The rest listen free but must endure advertising. Even though it has a market value of $5 billion, Pandora has yet to turn an annual profit.
“There is this irrational resistance for people to actually plunk down their credit card for streaming services,” said Ted Cohen, a digital music consultant with the firm TAG Strategic. “We’re 13 years into the Napster phenomenon of ‘music is free,’ and it’s hard to get people back into the idea that music is at least worth the value of a cup of Starbucks coffee a week.”READ REST OF STORY
