- 30. How do you harness it?
- 31. This is what big data is really about.
- 32. Asking questions and getting answers
- 33. Massive amounts of data. Machine generated VOLUME
- 34. Data is coming from a multitude of sources Mix of structured and un-structured (JSON, XML, CSV, Plain Text) Need a way to store it and and query it VARIETY
- 35. VARIETY Log files Activity Feeds Emails Device Streams Audio Files Videos
- 36. Data arrives at many different frequencies Need to be able to process real time. VELOCITY
- 37. Not all data that is stored is useful. Need to identify the useful data Need to wade through all the noise VERACITY
- 38. SOLUTIONS
- 39. Map/Reduce function map(String name, String document): // name: document name // document: document contents for each word w in document: emit (w, 1) function reduce(String word, Iterator partialCounts): // word: a word // partialCounts: a list of aggregated partial counts sum = 0 for each pc in partialCounts: sum += ParseInt(pc) emit (word, sum)

Editor's Notes
- At Splunk, our mission is to make machine data accessible, usable and valuable to everyone. Andthis overarching mission is what drives our company and product priorities.
- Splunk is the leading platform for machine data analytics with over 5,200 organizations using Splunk (as of 7/1/13) – from tens of GB to many tens of TBs of data PER DAY.Splunk software is optimized for real-time, low latency and interactivity.Splunk software reliably collects and indexes all the streaming data from IT systems and technology devices in real-time - tens of thousands of sources in unpredictable formats and types.The value from Splunking machine data is described as Operational Intelligence. This enables organizations to: 1. Find and fix problems dramatically faster2. Automatically monitor to identify issues, problems and attacks3. Gain end-to-end visibility to track and deliver on IT KPIs and make better-informed IT decisions4. Gain real-time insight from operational data to make better-informed business decisions
- The Lascaux cave paintings record the first known narrative stories. Telling stories through visualization of eventsMike Bostock,D3 and the NewYork Times VizCSS had to come from somewhere
