Big Data and Hadoop are latest and most in-demand technology today and for many coming decades.
You know why?
Data is being generated since centuries till this second, and 90% of all this data is generated in last two years. This data is still accelerating to generate in large velocity, volume and variety.
Traditional Data Base Management systems were inefficient to handle, that is Collect, Transfer, Store, Process and Analyse this Big Data generated suddenly. This data is generated from the increased use of digital and electronic devices.
Then entered the Big Data and Hadoop to the Data Management Industry.
It was able to manage large data generated quite efficiently. Hadoop is the most popular technology in Information Technology. The backbones of Hadoop which are – world’s most reliable storage layer – HDFS, a batch Processing engine – MapReduce and a Resource Management Layer – YARN makes Hadoop manage the Big Data in such an efficient manner.
The employees who were not upgraded in the Big Data skills like of the data scientist and data analyst are were laid off in huge number.
“Indian IT companies like Infosys and TCS laid off 56,000 people last year”
Same companies and organizations are hiring a big number of Big Data scientists: Check the jobs IBM Infosys Hortonworks
Industries other than IT are also hiring the Big Data and Hadoop Professionals.
Experienced from different fields are switching their jobs into Big Data. Even good number of freshers are getting into the industry.
