What is Big Data and why is it such a big deal?

A Brief History of Big Data Sources: Wikipedia, Forbes.com, and other articles

• 1941: “Information Explosion” term coined.• 1963: Physicist and science historian Derek Price concluded the number of new journals grown exponentially. • 1990: Computer Scientist Peter J. Denning, “Saving All the Bits”, what machines can we build to monitor, process, and understand the data, its meanings, and patterns? – Intelligence out of the data? • 1998: Steve Bryson et all, “Visually exploring gigabyte data sets in real time”, ACM, Section “Big Data for Scientific Visualization”.

A Brief History of Big Data Cont’dSources: Wikipedia, Forbes.com, and other articles

• 2001, Doug Laney, Meta Group, “3D Data Management, Controlling Data Volume, Velocity, and Variety” (More now: Veracity, Variability, and Value)

A Brief History of Big Data Cont’dSources: Wikipedia, Forbes.com, and other articles

• 2001 - 2003: Google outgrown as a result of new revenue model, 5 cents per click. Google is now a giant big data leader.

• 1994 – Present: Yahoo!, Hadoop Shop (10K Nodes), Genome, Big Data Analytics.

• 1994 – Present: Amazon, AWS Cloud.

• 2003 – Present: Facebook, Twitter, LinkedIn, etc.

• 2013 and beyond : Many others.

Population Growth Chart: Does it have something to do with Big Data? Machines, Satellites, Cameras, Internet, computers, and mobile phones are just “enablers” of big data.

Information Explosion. It is just the real beginning.

You got mail (too much).

You are embarrassed to admit you don’t know a lot of cool things happening in the world.

Don’t despair. You are not alone.

Big Data Opportunities

10


Big Data Opportunities

• Medical Research and Healthcare: Massive collected research and clinical information can be used to predict and prevent diseases, moving us from ‘sick care’ to ‘health care’. • Telecom: Traffic data and patterns can be utilized in real time to re-route.• Defense: Satellite images and other information can be meshed up to identify threats. • Utilities: Smart meter monitoring.• Public Safety: Pattern recognition and social media can help to predict crimes. • Financial Industry: Patten recognition and business rules to flag fraudulent activities.• Functional Areas: Investigational Search, Pricing Optimization, Risk Analysis, Churn Analysis, Behavior Analysis, Transactions Analysis, Revenue Assurance, Recommendation Engines, etc.

Where Big Data Can Shine

• Notes – Big Data Technology is not the replacement – Big Data is complementary – In some cases, Big Data is the only way to get things done – Big Data has its own challenges

Hadoop HDFS

Blocks (64M, 128M, etc.) are saved in different nodes with a replication factor ( default 3)

Big Data Challenges, Suggested Startup Strategy

22


Business urgency, time to market pressures Big Data start up needs careful planning Big Data needs infrastructure, software stacks, people, start up

plan Lack of Big Data Resources, Lack of Sponsorships (except in some

companies) Big Data is complex and multiple skill sets (mostly new to many

companies) – Infrastructure, Administration, Security, Programming, Testing, etc.

Skepticism about Big Data Integration with Existing Technologies and Systems

Can not develop isolated big data solutions Integration with existing systems will be a top challenge (requires

both sides to do additional work) Open Sources: Stability, Maturity, and Security

Big Data Start up Challenges


Full business needs and information requirements analysis. Business Drivers Revenue generation? Cost reduction? Customer retention? Compliance? Process Improvement? Fraud detection? Analytics? Dashboard? Solving a tough problem? Retiring/replacing technologies and systems?

Technology Evaluation and Selection Define requirements and objective first Evaluation a variety of technology stacks – develop a framework first

Executive Support for Start up Resources Prototyping, Discovery, and Planning

Rent Infrastructure in Cloud – VMWare, Amazon EC2, and others Use Spare Hardware and Network Bandwidth Assessment, Proposal. Project/Program Plan for next steps Start small and keep delivering

Architecture Design, Estimation, Business Case Obtain funding and executive sponsorships, owners, etc. SDLC, don’t forget Hardware, Security, Testing, etc.
