What is Big Data

Description: Big Data is the next big thing in computing. This video explains Big Data characteristics, technologies and opportunities.

Source: http://www.explainingcomputers.com

 
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 

Questions for discussion:

  1.  What is Big Data and why is it important?
  2. What potential applications do you see for Big Data and in what industries will this add the greatest value?

Sizing Up Big Data, Broadening Beyond the Internet

Looking for a better use for his skills, Mr. Hammerbacher departed to Silicon Valley less than a year later and joined Facebook. He started a team that began to mine the vast amounts of social network data Facebook was collecting for insights on how to tweak the service and target ads. He called himself and his co-workers “data scientists,” a term that has since become the hottest of job categories.

Facebook was a fabulous petri dish for data science. Yet after two and a half years, Mr. Hammerbacher decided it was time to move on, beyond social networks and Internet advertising. He became a founder of Cloudera, a start-up that makes software tools for data scientists. READ REST OF STORY 

Questions for discussion:

1. How would you describe to someone “What Big Data is?”

2.  What fields do you think Big Data will have the biggest impact?  The least impact?

Why Android Gets Apps Later Than IOS

Description: There are too many operating systems, devices, and models for app developers to keep up. This diversified market makes the future of apps look  more corporate than entrepreneurial.

Even though there are more Android phones than iPhones in the United States, the number and variety of Android apps lags compared to Apple’s offerings. For instance, Android users had to wait a year before they got Instagram or Pinterest apps. New research helps explain why.

There’s got to be more to the story than the number of phones. Flurry, a mobile-app analytics firm, released a report this week that helps explain the problem, laying out the challenges app developers face. It also shows that Android apps are unlikely to catch up and that small developers coding for either device will get squeezed out of the market READ REST OF STORY

 Questions for discussion:

1. Which operating systems or devices do you think would be most profitable for app developers to focus on?

2. How can app developers meet the needs of all users?

Netflix Announces $100,000 in Prizes for Coders

Description: Last night Netflix hosted a gathering at its spa-like headquarters for 200 or so members of the Clouderati—the engineers building out the computing infrastructure on which businesses will someday run. Netflix (NFLX) has a reputation for pushing the limits of cloud computing, running much of its movie streaming business on Amazon.com’s cloud rental system.

When it comes to infrastructure technology, we live in absurd times. Netflix—like Facebook (FB), LinkedIn (LNKD), Twitter, Yahoo (YHOO), and other Web celebs—open sources much of the software that underlies its operations. Put more bluntly, they fight for the right to heap money on the smartest engineers, then give away their work so that others can build on top of it. Together, all these companies are forging the cutting-edge cloud computing technology that mainstream companies will use in the years to come.

At its event, Netflix looked to turbocharge the process. The company announced $100,000 in prizes—$10,000 for 10 different awards—for volunteer coders who can develop interesting tools based on Netflix’s open-source code over the next six months. (Rules here.) The revelation of these prizes was met with great applause. Now the race is on for people who don’t work at Netflix to improve the company’s infrastructure. READ REST OF STORY

Questions for discussion:

1. What is the model that Netflix is using to develop a technology infrastructure?  How is it different from say companies like Microsoft and IBM?

2. DO you feel that Netflix’s model is the way IT development will happen in the future or do you see this as just a fad?

3.  What are the strengths and weaknesses of this model?
