Title: Introduction to Big Data


1
Big Data
  • What is it ?
  • What trends in IT support it ?
  • Some examples
  • What tools are used ?
  • The future ?

2
Big Data What is it ?
  • Very large data set volumes
  • Very long / unacceptable processing times
  • Very large data velocity ( inputs / outputs )
  • Very large varieties of data
  • High level of complexity

3
Big Data Supporting Trends
  • Moore's Law
  • An observation that the number of transistors on
    integrated circuits doubles every two years.

4
Big Data Supporting Trends
  • Kryder's Law
  • The density of storage is increasing and the cost
    decreasing at a rate faster than Moore's Law.

5
Big Data Supporting Trends
  • Butter's Law
  • Relates to network capacity and states that the
    cost of sending data over an optical network
    halves every nine months.

6
Big Data Supporting Trends
  • Parallel Processing
  • Task parallelism, breaking the task down into its
    constituent parts and processing them
    simultaneously.

7
Big Data Examples
  • NASA Climate Simulation
  • 32 petabytes
  • The Large Hadron Collider
  • 25 petabytes annually, 200 petabytes after
    replication
  • Wall mart
  • 2.5 petabytes per hour

8
Big Data Tools
  • Hadoop
  • Hadoop is often used at the server level to
    organise the cluster along with a NoSQL database
    for data storage.
  • NoSQL
  • Databases ( non sql ) that use looser consistency
    models than relational databases. Performance
    gains via simplification using key value stores.
  • MPP
  • Massively parallel processing and analytics
    databases. Fast for data aggregation but slow for
    data loading.

9
Big Data The Future
  • Data sets will continue to grow
  • Storage unit costs will continue to decrease
  • Processing costs will decrease
  • Network capacity will continue to grow
  • Data growth may exceed processing capacity
