Why Big Data?

Understanding the Basics

Why Big Data?

Gartner’s Hype Cycle on Big Data

Key Technologies• Accessible storage (non-relational) in cloud: Amazon S3, Azure Blob &

Table storage, Google Cloud Storage

• In memory databases & grids: MemSQL, XAP (Gigaspaces ), SAP Hana

• Parallel processing frameworks: Hadoop

• Online analytics frameworks: Google BigQuery, Hive

• Data stream processing: Twitter Storm

• Complex event processing: Oracle CEP Server, Microsoft StreamInsight

• Sentiment analysis – Radian6

Big Data Principles1. More: store over trash

2. Messy: quantity over quality

3. Correlation: what over why

Understanding the Basics Move the Compute to the Data

Characteristics of Big Data

MapReduce

Think of the following problem...

What if we parallelize?

Hadoop On Windows Server

Hadoop On Windows Azure

Deploying and Interacting With a Hadoop Cluster on Azure

step-by-step walktrough

Objectives1. Run a basic Java MapReduce program using a Hadoop jar file

2. Import data from the Windows Azure Marketplace into a Hadoop on Azure cluster using the Interactive Hive Console

Prerequisites1. Access to a Hadoop on Azure account

2. Request an invitation to the Preview Feature

Hadoop Sample Gallery

Objective #1: Basic MapReduce Task• We will use the Pi Estimator sample job

• Distributed Pi Estimator with 16 maps, each will compute 10 million samples

Pi Estimator

2r

r=1

• Uses the Monte Carlo Simulation method to compute π

Pi Estimator• Uses the Monte Carlo Simulation method to

compute π

Pi Estimator: Running the Job

Pi Estimator: And the result is.... • 160.000.000 random

points• 16 mappers• 10.000.000 samples /

map

• Computed in 65.108 seconds

Objective #2: Import data from the Windows Azure Marketplace into a Hadoop

• Windows Azure Marketplace is a cloud one-stop-shop for premium data and applications

• We will see how we can use the „2006 – 2008 Crime in the US” dataset to play with on Hadoop using Hive

Windows Azure Marketplace

Apache Hive

• Data Warehouse infrastructure built on top of Hadoop

• Provides data summarization, query and analysis

• Initially developed by Facebook, now an Apache project

Apache Hive: Features

• Analysis of large datasets stored in Hadoop-compatible file-systems

• Provides a SQL-like language called HiveQL while maintaining full support for map/reduce

• By default, stores data in Apache Derby database

Microsoft Big Data RoadmapTo accelerate the delivery of Microsoft’s Hadoop based solution for Windows Server and service for Windows Azure, Microsoft is announcing a partnership with HortonworksMicrosoft is committed to broadening accessibility and usage of Hadoop to end users, developers and IT professionals in organizations of all sizes

Microsoft is announcing an end-to-end roadmap for Big Data that embraces Apache HadoopTM by distributing enterprise class Hadoop based solutions on both Windows Server and Windows Azure

Microsoft is extending its leadership in business intelligence and data warehousing to provide insights to all users by activating new types of data of any size

Things to do1. Get a trial of Windows Azure2. Subscribe to the Preview Program of Hadoop on

Azure3. Write your first Map/Reduce job

4. Have a talk in autumn at CodeCamp on your experience with Big Data

Thank you
