4. Big Data - definition
popular term used to describe the
exponential growth and availability of
data, both structured and
unstructured.
collection of data from traditional and
digital sources inside and outside your
company that represents a source for
ongoing discovery and analysis.
may refer to both volume of data as
well as the tools and processes

5. 3 Vs of Big Data

6. Need for Big Data
2.7 ZB of data in Digital Universe
Today
FB stores and analyzes 30+ PB of
data
Walmart data exceeds 2.5 PB
better decision making and increased
operational efficiency

7. When to go for a Big Data
Soln
Analyze all types of data
Most or all of the data to be analyzed
Iterative and exploratory
Business measures not predetermined
Traditional warehouse not suitable for
unstructured data and schema
compliant

8. Gartner’s Hype Cycle

9. Retail – Pricing Optimization
Analyze millions of sold or items for sale
Valuable insights about customers and
markets in quicker timeframes
Aggregate data from multiple channels in
multiple formats
Day long jobs complete in minutes

10. Retail – Smart shopping exp
Pricing data, POS, txns, Social media,
call center records, promotions
Better understanding of customer
preferences, shopping patterns
Geo location apps - deliver
personalized marketing experience

11. Big Data in Finance
Customer segmentation
◦ Correlate purchase history, profile info,
behaviour on social media
◦ Generate portfolio advice
Fraud Detection systems
Wealth Management
◦ Investment Research – try out new
investment ideas, improve algorithmic trading
◦ Customer knowledge – unified view of
customer

12. Big Data in Finance
Regulatory Compliance
◦ Impact of Credit Crisis ‘08 – regulatory
compliance
◦ Stringent monitoring and reporting of data
Risk Management
◦ Better analysis of investment positions and risk
metrics

13. Big Data in Healthcare
EMR – Electronic Medical Records
initiative in US
Complete digitization of a patient’s
medical info such as profile, disease
treatment, pharmacy visits etc
Shared across networks
Slow adoption and challenges in
aggregation

14. Big Data in Healthcare
Predict health issues
◦ Build Model that predicts patient’s risk
◦ Hospital to do followup with high-risk
patients to avoid hospitalization
Predicting outbreaks
◦ IBM Research project -STEM
◦ Model – correlates disease data with
climate and temperature
◦ Can predict disease outbreak for regions
expecting climatic change

15. Big Data – Internet of
Things
Data generated by machine – RFID
chips implanted in devices
3 phases
◦ Data ingestion – cost
◦ Data storage - cost
◦ Analytics – real value
Outsouce phases 1 and 2 to DBAAS
(redshift, hortonworks, cloudera)

16. UPS – Case study
Aim
◦ Find the fastest and most fuel-efficient
way to deliver packages to customers
ORION research project
◦ Captures driver behaviour and safety
habits thru GPS
◦ Sensor data on fuel emissions and
consumption
◦ Monitors deliveries and customer service
◦ Runs advanced algorithms to optimize
routes

17. UPS – Case Study
early testing in 2011-2012 for 10k
routes – 1.5 million gallons of fuel
saved
Complete deployment in 55000 routes
throughout North America by 2017

18. Big Data – Technologies
Mapreduce
◦ programming paradigm allows massive
job execution parallely across thousands
of servers
◦ Map task - input dataset is converted into
a different set of key/value pairs
◦ Reduce task - several of the outputs of
the "Map" task are combined to form a
reduced set of tuples

19. Big Data - Technologies
Hadoop
◦ Most popular open-source implementation
of mapreduce
◦ Can work with multiple forms of data
◦ run processor-intensive machine learning
jobs
HIVE
◦ Developed by FB and later made open-
source
◦ SQL like feature on top of hadoop
◦ Query data stored in a hadoop cluster

20. Big Data - Technologies
PIG
◦ Scripting language
◦ Transforms data present in Hadoop
cluster
◦ Developed by Yahoo and made open-
source
NoSQL
◦ Schema less databases
◦ Storage and retrieval of huge amounts of
unstructured data
◦ Scalable, flexible and cloud-friendly but
less consistent

21. Other Big Data
Technologies
Search engines – Lucene, Solr,
ElasticSearch, Amazon CloudSearch
Stream Processing
◦ Apache Storm, Apache Spark, Cloudera’s
Impala, Yahoo’s S4 and Apache Tez

22. Big Data – Vendors
Amazon
◦ Elastic Map Reduce – Amazon’s hadoop
distribution to be run on AWS
infrastructure
◦ “largest adoption of hadoop platforms in
the market” – Forrester report
Cloudera
◦ Uses many aspects of open-source
hadoop
◦ Lot of features built on top of its hadoop
namely Cloudera Manager and Impala
