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

Will the Internet of Things Changes Everything?

Description: Currently in the business world we are witnessing something like the epic collision of two galaxies — a rapid convergence of two very unlike systems that will cause the elements of both to realign. It’s all thanks to the Internet of Things.

If you are not familiar with the term, the Internet of Things refers to a dramatic development in the internet’s function: the fact that, even more than among people, it now enables communication among physical objects. By 2015, according to my own firm’s projections, not only will 75 percent of the world’s population have access to the internet. So will some six billion devices. The fact that there will be a global system of interconnected computer networks, sensors, actuators, and devices all using the internet protocol holds so much potential to change our lives that it is often referred to as the internet’s next generation.
For managers, this development creates challenges both long-term and urgent. They need to envision the valuable new offerings that become possible when the physical world is merged with the virtual world and potentially every physical object can be both intelligent and networked. And, starting now, they must create the organizations and web-based business models that can turn these ideas into reality.  READ REST OF STORY

As the marketers explained to Pole — and as Pole later explained to me, back when we were still speaking and before Target told him to stop — new parents are a retailer’s holy grail. Most shoppers don’t buy everything they need at one store. Instead, they buy groceries at the grocery store and toys at the toy store, and they visit Target only when they need certain items they associate with Target — cleaning supplies, say, or new socks or a six-month supply of toilet paper. But Target sells everything from milk to stuffed animals to lawn furniture to electronics, so one of the company’s primary goals is convincing customers that the only store they need is Target. But it’s a tough message to get across, even with the most ingenious ad campaigns, because once consumers’ shopping habits are ingrained, it’s incredibly difficult to change them.  READ REST OF STORY
