Introduction

There has been a lot of investment in Big Data by various companies in last few years. This rise in usage of big data analytics has resulted in high demand of skilled big data professionals. While there has been a lot of debate over usefulness of this spend, there is a clear increase in the jobs on Big Data. Here is what a quick search on indeed tells:

Given the sharp increase in demand, big data has become a lucrative area to upskill yourself. However, if you are some one like me, who needs a good overview and understanding of practical benefits before learning something in a more formal fashion, you will probably struggle to find structured resources as I did some time back.

There are a lot of technologies and terminologies associated with Big Data, which can act as an additional road block to get you started. Names like Hadoop, MapReduce, Spark, MongoDB, Hive take some time to get used to! After receiving an overwhelming response on my previous article on Top YouTube Videos on Machine Learning, Deep Learning, Neural Network and looking at the lack of structured resources, the answer was simple! Here’s another YouTube special for Big Data aspirants – basically my take on immersing yourself on Big Data!
