Not This Type of Nerd

Data Nerd Coffee Talk We saw Cloudera as the lone open source champion of Hadoop and the EMC/Greenplum/MapR initiative as a more closed and proprietary long shot We are the only real-time data store that combines fine-grained security controls, scalability to the 10s of petabytes, flexible schemas for unstructured and semi-structured information, and diverse analytical capabilities I am working on a framework to allow construction of large-scale analytical queries on unstructured data The IoT and big data are clearly growing apace, and are set to transform many areas everyday life. But which particular sectors are likely to feel the IoT/big data disruption first?

What is Big Data?

What is Big Data? Big data is like teenage sex: Everyone talks about it, Nobody really knows how to do it, Everyone thinks everyone else is doing it, So everyone claims they are doing it -Dan Ariely

40 ZETTABYTES 2.5 Quintillion Bytes of data will be created by 2020, an increase of 300 times from 2005 6 BILLION PEOPLE have cell phones of data created each day Volume SCALE OF DATA Most companies in the US have at least 100 TERABYTES of data stored The Four V s of BIG DATA: Global healthcare data size estimated to be 150 EXABYTES Variety DIFFERENT FORMS OF DATA 400 MILLION TWEETS are sent per day by about 200 million monthly users By 2015, it s anticipated there will be 420 MILLION WEARABLE, WIRELESS HEALTH MONITORS 4 BILLION+ HOURS OF VIDEO are watched on YouTube each month NYSE captures 1 TB OF TRADE INFORMATION during each trading session Velocity STREAMING DATA Source: McKinsey Global Institute Modern cares have close to 100 SENSORS that monitor fuel levels, tire pressure, etc Problems that are unsolvable using traditional tools 1 IN 3 BUSINESS LEADERS don t trust the information they user to make decisions Veracity UNCERTAINTY OF DATA Poor data quality costs the US economy around $3.1 TRILLION A YEAR 27% OF RESPONDENTS were unsure of how much of their data was inaccurate

Hadoop Hadoop Distributed File System (HDFS) Commodity Hardware Files stored as blocks Reliability achieved through replication (clusters) Master Node [few] JobTracker: Distributes Map/Reduce Tasks TaskTracker: Receives Map/Reduce Tasks NameNode: Coordinate meta-data DataNode: Stores & replicates data across cluster Worker Node: Processing Power [many] No data caching Open-Source Framework Allows for Multiple Programming Language Parallel processing Task-based programming logic Components will fail at high rate (and that s ok) Map / Reduce (aka Divide and Conquer) Data will be contained in a relatively small number of big files Data files are write-once Lots of streaming reas Higher sustained throughput across large amounts of data Distributions & Programming Tools
