The Reality of Bigdata - #Beltech2014

  1. 1. The Reality of Big Data
  2. 2. #beltech2014
  3. 3. #1 – What problem are you trying to solve?
  4. 4. Most of SME’s problems aren’t Big Data, it’s just data.
  5. 5. Without a question you are wasting your time.
  6. 6. #2 – Data will need cleaning
  7. 7. Roughly 80% of your data project will be getting the data into shape before processing.
  8. 8. Btiany Spears
  9. 9. #3 – Hadoop, on it’s own, will NOT give you the answers.
  10. 10. #3 – Hadoop, on it’s own, will NOT give you the answers. (The Big Data version of “putting it in the cloud”)
  11. 11. If anyone says, “will Hadoop just give us the answers” or “put it in the cloud”, do this….
  12. 12. Spit on one, or both, of their feet and bite your thumb while shouting: “The fig of Spain!”.
  13. 13. #4 – Do you actually need Hadoop?
  14. 14. A well crafted algorithm may give you more benefit.
  15. 15. It’s about knowing the right questions.
  16. 16. And refining and refining and refining…..
  17. 17. The first run won't work at all The second only makes you wonder The third will have you on your knees.....
  18. 18. #5 – Data changes
  19. 19. …especially when you don’t own it.
  20. 20. If you feel your data has value then retain it.
  21. 21. If your data passes over the “creepy line” then definitely retain it.
  22. 22. #6 – Skills are in short supply
  23. 23. Work with what you have.
  24. 24. Play with data, it’s the best way to learn.
  25. 25. Collaborate with others to fill the skills gaps.
  26. 26. Thank you http://about.me/jasebell @hadooping
