  5. 5. Slide5 www.edureka.co/big-data-and-hadoop If you want to do some Real Time Analytics, where you are expecting the result quickly, Hadoop should not be used directly Hadoop works on Batch processing, hence the response time is high Day1 Day2 Day 3 Day 4 ......... ………. ………. Day n Day1 Day2 Day 3 Day 4 ......... ………. ………. Day n Input Data Processing Data Input Data Processing Data Input Data Processing Data Input Data Processing Data using MR Time Lag Real Time Analytics

  8. 8. Slide8 www.edureka.co/big-data-and-hadoop Hadoop is not a replacement for your existing data processing infrastructure After processing the data in Hadoop you need to send the output to relational database technologies for BI, decision support, reporting etc. It is not going to replace your database, but your database isn’t likely to replace Hadoop either Different tools for different jobs Not a Replacement for Existing Infrastructure
  9. 9. Slide9 www.edureka.co/big-data-and-hadoop Hadoop framework is not recommendable for small structured datasets as you have other tools available in the market which can do this work quite easily and at a fast pace than Hadoop like MS excel, RDBMS etc. For a small data analytics, Hadoop can be costlier than other tools Merge all the small files into one Multiple Smaller Datasets –Accepted Way

  11. 11. Slide11 www.edureka.co/big-data-and-hadoop Unless you have a better understanding of the Hadoop framework, its not suggested to use Hadoop for production Learning Hadoop and its eco-system tools and deciding which technology suits your need is again a different level of complexity Novice Hadoopers
  12. 12. Slide12 www.edureka.co/big-data-and-hadoop Many enterprises -especially within the highly regulated industries dealing with sensitive data -aren’t able to move as quick as they would like, towards implementing Big Data projects and Hadoop “Example Health-care data used by Insurance companies to calculate premium” Where Security is the Primary Concern? They don’t have to hesitate though, as many of the security and compliance challenges are being continuously worked upon and can be surmountable (for example, by using Apache Accumulo on top of Hadoop).

  14. 14. Slide14 www.edureka.co/big-data-and-hadoop When To Use Hadoop
  15. 15. Slide15 www.edureka.co/big-data-and-hadoop Your have different types of data: structured, semi-structured and unstructured The data set is huge in size i.e. several Terabytes or Petabytes You are not in a hurry for Answers Data Size and Data Diversity
  16. 16. Slide16 www.edureka.co/big-data-and-hadoop To implement Hadoop on your data you should first understand the level of complexity of data and the rate in which it is going to grow So we need a cluster planning, it may begin with building a small or medium cluster in your industry as per data (in GBs or few TBs ) available at present and scale up your cluster in future depending on the growth of your data Future Planning
  17. 17. Slide17 www.edureka.co/big-data-and-hadoop Hadoop can be integrated with multiple analytic tools to get the best out of it, like M-Learning, R , Python, Spark, MongoDB etc. Multiple Frameworks for Big Data
  18. 18. Slide18 www.edureka.co/big-data-and-hadoop When you want your data to be live and running forever, it can be achieved using Hadoop’s scalability Lifetime Data Availability
