Big data is large amounts of unstructured data that require new techniques and tools to analyze. Key drivers of big data growth are increased storage capacity, processing power, and data availability. Big data analytics can uncover hidden patterns to provide competitive advantages and better business decisions. Applications include healthcare, homeland security, finance, manufacturing, and retail. The global big data market is expected to grow significantly, with India's market projected to reach $1 billion by 2015. This growth will increase demand for data scientists and analysts to support big data solutions and technologies like Hadoop and NoSQL databases.

1. The Next Frontier for Innovation, Competition and Productivity

3. • ‘Big Data’ is similar to ‘small data’, but
bigger
•…but having data bigger it requires different
approaches:
• Techniques, tools and architecture
•…with an aim to solve new problems
• …or old problems in a better way

5. Why Big Data
• Key enablers of appearance and growth of Big Data
are
–Increase of storage capacities
–Increase of processing power
–Availability of data
–Every day we create 2.5 quintillion bytes of data;
90% of the data in the world today has been
created in the last two years alone

6. Big Data Analytics
• Examining large amount of data
• Appropriate information
• Identification of hidden patterns, unknown correlations
• Competitive advantage
• Better business decisions: strategic and operational
• Effective marketing, customer satisfaction, increased
revenue

7. Applications for Big Data Analytics
Homeland Security
FinanceSmarter Healthcare
Multi-channel sales
Telecom
Manufacturing
Traffic Control
Trading Analytics Fraud and Risk
Log Analysis
Search Quality
Retail: Churn, NBO

8. Healthcare
• 80% of medical data is unstructured and is clinically
relevant
• Data resides in multiple places like individual EMRs,
lab and imaging systems, physician notes, medical
correspondence, claims etc
• Leveraging Big Data
• Build sustainable healthcare systems
• Collaborate to improve care and outcomes
• Increase access to healthcare

9. Market Size
Source: Wikibon Taming Big Data
By 2015 4.4 million IT jobs in Big Data ; 1.9 million is in US itself

10. India – Big Data
• Gaining attraction
• Huge market opportunities for IT services (82.9% of
revenues) and analytics firms (17.1 % )
• Current market size is $200 million. By 2015 $1
billion
• The opportunity for Indian service providers lies in
offering services around Big Data implementation
and analytics for global multinationals

11. India will require a minimum of 1 lakh data scientists in the next couple of years
in addition to data analysts and data managers to support the Big Data space.

14. NoSQL : non-relational or at least non-SQL database
solutions such as HBase (also a part of the Hadoop
ecosystem), Cassandra, MongoDB, Riak, CouchDB, and
many others.
Hadoop: It is an ecosystem of software packages,
including MapReduce, HDFS, and a whole host of other
software packages
