4. What is Hadoop? • A scalable fault-tolerant distributed system for data storage and processing (open source under the Apache license) • Scalable data processing engine • Hadoop Distributed File System (HDFS): self-healing high-bandwidth clustered storage • MapReduce: fault-tolerant distributed processing • Key value • Flexible -> store data without a schema and add it later as needed • Affordable -> cost / TB at a fraction of traditional options • Broadly adopted -> a large and active ecosystem • Proven at scale -> dozens of petabyte + implementations in production today Copyright 2010 Cloudera Inc.

8. What is common across Hadoop-able problems? Nature of the data • Complex data • Multiple data sources • Lots of it Nature of the analysis • Batch processing • Parallel execution • Spread data over a cluster of servers and take the computation to the data Copyright 2010 Cloudera Inc. All rights reserved 8
9. What Analysis is Possible With Hadoop? • Text mining • Collaborative filtering • Index building • Prediction models • Graph creation and • Sentiment analysis analysis • Risk assessment • Pattern recognition Copyright 2010 Cloudera Inc. All rights reserved 9
10. Benefits of Analyzing With Hadoop • Previously impossible/impractical to do this analysis • Analysis conducted at lower cost • Analysis conducted in less time • Greater flexibility Copyright 2010 Cloudera Inc. All rights reserved 10

12. 1. Modeling True Risk Copyright 2010 Cloudera Inc. All rights reserved 12
13. 1. Modeling True Risk Solution with Hadoop • Source, parse and aggregate disparate data sources to build comprehensive data picture • e.g. credit card records, call recordings, chat sessions, emails, banking activity • Structure and analyze • Sentiment analysis, graph creation, pattern recognition Typical Industry • Financial Services (Banks, Insurance) Copyright 2010 Cloudera Inc. All rights reserved 13
14. 2. Customer Churn Analysis Copyright 2010 Cloudera Inc. All rights reserved 14
15. 2. Customer Churn Analysis Solution with Hadoop • Rapidly test and build behavioral model of customer from disparate data sources • Structure and analyze with Hadoop • Traversing • Graph creation • Pattern recognition Typical Industry • Telecommunications, Financial Services Copyright 2010 Cloudera Inc. All rights reserved 15
16. 3. Recommendation Engine Copyright 2010 Cloudera Inc. All rights reserved 16
17. 3. Recommendation Engine Solution with Hadoop • Batch processing framework • Allow execution in in parallel over large datasets • Collaborative filtering • Collecting ‘taste’ information from many users • Utilizing information to predict what similar users like Typical Industry • Ecommerce, Manufacturing, Retail Copyright 2010 Cloudera Inc. All rights reserved 17
18. 4. Ad Targeting Copyright 2010 Cloudera Inc. All rights reserved 18
19. 4. Ad Targeting Solution with Hadoop • Data analysis can be conducted in parallel, reducing processing times from days to hours • With Hadoop, as data volumes grow the only expansion cost is hardware • Add more nodes without a degradation in performance Typical Industry • Advertising Copyright 2010 Cloudera Inc. All rights reserved 19
20. 5. Point of Sale Transaction Analysis Copyright 2010 Cloudera Inc. All rights reserved 20
21. 5. Point of Sale Transaction Analysis Solution with Hadoop • Batch processing framework • Allow execution in in parallel over large datasets • Pattern recognition • Optimizing over multiple data sources • Utilizing information to predict demand Typical Industry • Retail Copyright 2010 Cloudera Inc. All rights reserved 21
22. 6. Analyzing Network Data to Predict Failure Copyright 2010 Cloudera Inc. All rights reserved 22
23. 6. Analyzing Network Data to Predict Failure Solution with Hadoop • Take the computation to the data • Expand the range of indexing techniques from simple scans to more complex data mining • Better understand how the network reacts to fluctuations • How previously thought discrete anomalies may, in fact, be interconnected • Identify leading indicators of component failure Typical Industry • Utilities, Telecommunications, Data Centers Copyright 2010 Cloudera Inc. All rights reserved 23
24. 7. Threat Analysis Copyright 2010 Cloudera Inc. All rights reserved 24
