Lessons Learned : Scaling Hadoop and BigData in Cloud (Amazon EMR )


Vijay Rayapati


High level technology and business perspective around BigData including how to and why leverage cloud based platforms like Amazon EMR along with Map Reduce for data analysis.

Expect to learn concepts, insights, challenges in problem solving, scaling, dealing with data and performance tuning.


I will be talking about Hadoop, Map Reduce in general and how to leverage Cloud based platforms like Amazon EMR for Hadoop Map Reduce jobs. Will be sharing lessons learned from managing hyper scale production Hadoop clusters and tuning for performance in general – Think 68400 GB RAM, 26000 CPUs and 1700000 GB Disks :)

This talk is aimed at providing insights and challenges while building large scale data analysis platforms using Hadoop and technical challenges involved in scaling algorithms to data storage to json parsers to in-memory data stores to managing 100’s of jobs.


Basic understanding of Hadoop will be good.
