4 The Four V s Volume Use greater amounts of data Variety Use more types of data Velocity Use data more quickly Veracity Use uncertain data 7 Big Data is All Data and All Paradigms Transactional & Application Data Machine Data Social Data Enterprise Content Volume Velocity Variety Variety Structured Structured Unstructured Unstructured Throughput Ingestion Veracity Volume 8 4

5 PARADIGMENWECHSEL How is Big Data transforming the way organizations analyze information and generate actionable insights? Paradigm shifts enabled by big data Leverage more of the data being captured TRADITIONAL APPROACH BIG DATA APPROACH All available information Analyzed information All available information analyzed Analyze small subsets of information Analyze all information 10 5

6 How is Big Data transforming the way organizations analyze information and generate actionable insights? Paradigm shifts enabled by big data Reduce effort required to leverage data TRADITIONAL APPROACH BIG DATA APPROACH Small amount of carefully organized information Large amount of messy information Carefully cleanse information before any analysis Analyze information as is, cleanse as needed 11 How is Big Data transforming the way organizations analyze information and generate actionable insights? Paradigm shifts enabled by big data Data leads the way and sometimes correlations are good enough TRADITIONAL APPROACH BIG DATA APPROACH Hypothesis Question Data Exploration Answer Data Insight Correlation Start with hypothesis and test against selected data Explore all data and identify correlations 12 6

7 How is Big Data transforming the way organizations analyze information and generate actionable insights? Paradigm shifts enabled by big data Leverage data as it is captured TRADITIONAL APPROACH BIG DATA APPROACH Data Analysis Data Repository Analysis Insight Insight Analyze data after it s been processed and landed in a warehouse or mart Analyze data in motion as it s generated, in real-time 13 APACHE HADOOP 7

8 It s easy to forget just how big the data really is! Datasets are vast Facebook daily logs ~ 60 TB 1,000 genomes project ~ 200 TB Google web index ~ 10+ PB Storage is cheap Cost of a commodity 1TB drive ~ $50 A terabyte is still a lot of data! Time to read 1TB from a single disk: ~ 6 50 MB/second!! As data gets big, traditional approaches no longer work Distributed systems are the only way to scale 15 What is Hadoop? Apache Hadoop = free, open source framework for data-intensive applications Inspired by Google technologies (MapReduce, GFS) Well-suited to batch-oriented, read-intensive applications Originally built to address scalability problems of Nutch, an open source Web search technology Enables applications to work with thousands of nodes and petabytes of data in a highly parallel, cost effective manner CPU + disks of commodity box = Hadoop node Boxes can be combined into clusters New nodes can be added as needed without changing Data formats How data is loaded How jobs are written 16 8

9 How files are stored: HDFS Key ideas: Divide big files in blocks and store blocks randomly across cluster Provide API to ask: where are the pieces of this file? => Programs can be shipped to nodes for parallel distributed processing Blocks Cluster Logical File 17 HDFS stores data across multiple nodes

10 HDFS assumes nodes will fail, so it achieves reliability by replicating data across multiple nodes 19 How Files are Processed: MapReduce Common pattern in data processing: apply a function, then aggregate grep "World Cup *.txt wc l User simply writes two pieces of code: mapper and reducer Mapper code executes on every split of every file Reducer consumes/aggregates mapper outputs The Hadoop MR framework takes care of the rest (resource allocation, scheduling, coordination, temping of intermediate results, storage of final result on HDFS) Splits Cluster Map Map Reduce Map Result 3 20 Logical File 10

11 Logical MapReduce Example: Word Count map(string key, String value): // key: document name // value: document contents for each word w in value: EmitIntermediate(w, "1"); reduce(string key, Iterator values): // key: a word // values: a list of counts int result = 0; for each v in values: result += ParseInt(v); Emit(AsString(result)); Content of Input Documents Hello World Bye World Hello IBM Map 1 emits: < Hello, 1> < World, 1> < Bye, 1> < World, 1> Map 2 emits: < Hello, 1> < IBM, 1> Reduce (final output): < Bye, 1> < IBM, 1> < Hello, 2> < World, 2> 21 WordCount 22 11

12 So What Does This Result In? Easy To Scale Fault Tolerant and Self-Healing Data Agnostic Extremely Flexible BUT you need programming skills 23 EIN EINFACHES BEISPIEL FÜR TEXTANALYSE Aus einer Bachelorarbeit Wirtschaftsinformatik FH Brandenburg 12

23 Ohne Analytics ist BigData Einfach nur ein Sack voll Daten MYTH: Big Data geht nur um MEHR Daten MYTH: Big Data = Hadoop... fertig MYTH: Big Data ersetzt alles Vorhandene, Tot dem RDBMS und keinerlei Governance MYTH: NoSQL = no SQL... niemals MYTH: Big Data sind unstrukturierte Daten und nur für Meinungsanalysen 45 How are leading companies transforming their data and analytics environment? Big Data Hadoop There s a belief that if you want big data, you need to go out and buy Hadoop and then you re pretty much set. People shouldn t get ideas about turning off their relational systems and replacing them with Hadoop As we start thinking about big data from the perspective of business needs, we re realizing that Hadoop isn t always the best tool for everything we need to do, and that using the wrong tool can sometimes be painful. Ken Rudin Head of Analytics at Facebook 46 23

24 Big Data is about more than just Hadoop Data may be structured, un-structured, static, in-flight (or all of above) Data at rest Huge volumes of data on disk Structured or semi-structured May or may not have schemas Too large for traditional tools Need to process in place Data in Motion In-flight, frequently not stored Tremendous velocity, high bandwidth Diverse data sources Frequently unstructured, semi-structured Ultra low-latency processing required 47 InfoSphere Streams delivers analytics for data in-motion Real time delivery ICU Monitoring Environment Monitoring Scale-out architecture for massive linear scalability Sophisticated analytics with pre-built toolkits & accelerators Comprehensive development tools to build applications with minimal learning Algorithmic Trading Millions of events per second Powerful Analytics Cyber Security Government / Law enforcement Telco Churn Prediction Smart Grid Microsecond Latency Traditional / Non-traditional data sources 48 Video, audio, networks, social media, etc 24

26 Why SQL on Hadoop? Hadoop stores large volumes and varieties of data SQL gets information and insight out of Hadoop SQL leverages existing IT skills resulting in quicker time to value and lower cost 51 SQL on Hadoop and Hive Hadoop can process data of any kind (as long as it's splittable, etc) A very common scenario: Tabular data Programs that query the data Java Hadoop APIs are the wrong tool for this Too low level, steep learning curve Require strong programming expertise Universally accepted solution: SQL Enter Hive... 1.Impose relational structure on plain files 2.Translate SELECT statements to MapReduce jobs 3.Hide all the low level details 52 26

28 Why names are difficult? There are no consistent standards for names. Some countries mandate certain standards but they differ from country to country, and most countries have no standards. Names can contain a variety of OPTIONAL information that can make the same name appear very differently. Ben Al Haden (Anglo) Bin Al-Hadin (son of somebody who came from the city of Hadin) Bin Al Hadin (son of Hadin) Bint Ali Hadin Renato Loffreda Mancinelli = Renato Mancinelli <> Renato Loffreda Using the anglo rules 55 IBM InfoSphere Identity Insight Solutions Commercially available Identity Analytics and Relationship Detection software Identity Insight 3 Key Functionalities: Who is who? No matter how hard they try to hide - Who knows who? The infamous hiding behind the innocuous - Who does what? Alerts you when bad guys do bad things Who Is Who?????? Who Knows Who Who Does What Entity Analytics is a methodical process of detecting like and related entities across large, sparse, and disparate collections of data, that is both new and old, internal and external, using advanced techniques to establish connections that are not obvious

29 BIG DATA ANALYTICS BEISPIELE Predictive Maintenance bei Union Pacific Predictive analytics help Union Pacific to predict certain derailments days or even weeks before they are likely to occur. Using thermometers, acoustic and visual sensors on the underside of each of its rail carriages they can detect and analyse imminent problems with tracks and wheels. In order for all the data to be transmitted over the vast rail system, they have deployed a fibre optic communications network throughout its rail system. Although a train derailment does not have to be a large accident, small errors can result in vast delays and with trains operational on any given day this can become very expensive

Landwirtschaft 4.0 nennen das die Experten eine Parallele zur Industrie 4.0, in der Maschinen und Werkstücke miteinander kommunizieren. 365FarmNet nennt das Claas und holt mit Erfolg auch die Konkurrenz auf diese erste universelle Managementplattform. 59 Handel Luxottica nutzt statistische Methoden auf einem Verhaltensmodell, um Kunden über Identitäten hinweg zu segmentieren und bewerten. 10% improvement in marketing effectiveness 100 million customers can be down-selected to the highest value individuals Target individual customers based on unique preferences and histories Solution Components 60 Customer Intelligence Appliance Software Twin Fin 12 PDA IBM Campaign IBM Enterprise Marketing Operations Business Challenge: Luxottica, the eyewear giant with nearly 100 million customers in eight house brands on the company s numerous websites and in retail stores, generates massive amounts of data, the majority of which was housed and managed by outside data and marketing vendors. Lacking a holistic understanding and view of the customers, marketers struggled to nurture customer relationships, seize cross-sell and up-sell opportunities, personalize campaigns and acquire new customers during the shopping process. The Smarter Solution: After a successful proof of concept, the company is deploying an advanced Customer Intelligence analytics appliance, built on a high-performance platform that integrates online and physical customer data from multiple sources. The resulting 360-degree omni-channel customer view will not only help the retailer identify its most profitable sales channels, but also segment, track and score customers down to the persona level based on thousands of behavioral attributes, and refine and personalize marketing campaigns. The results of the POC were eye-opening, revealing unprecedented and actionable insight into omni-channel customers we had never seen or analyzed before. Chief Digital Officer 30
