4. Managing Big Data

We are living in a world wherein every second we generate huge volumes of data. There arises a need to manage this vast amount of data called big data.

Big Data Distribution

From the above chart, we can see that the unstructured data is increasing exponentially. For managing such huge data, we need Big Data technologies like Hadoop. According to the Google report, since the dawn of civilization till 2003 mankind had generated 5 exabytes of data. But now we are producing 5 exabytes of data every two days. Thus, there is an increasing need for a cost-effective and reliable solution that handles Big Data. Apache Hadoop proves to be the best rescue in such a situation.

Hadoop with its economical feature and robust architecture is the best fit for storing and processing Big data.

5. Exponential Growth of Big Data Market

As per the Forbes report, “Hadoop Market is expected to reach $99.31B by 2022 at a CAGR of 42.1%”. Over the last few years, Big Data is a big game-changer in most of the industries. The huge number of companies belonging from various domains have adopted Big Data. Companies, by using Big Data tools like Apache Hadoop, Apache Spark, examine large data sets for identifying hidden patterns to discover unknown correlations, customer preferences, market trends, and other useful business information.

In India, the big data analytics sector will grow eightfold. As per the NASSCOM, big data analytics will reach USD 16 billion by 2025 from USD 2 billion.

With the rising Big data market, the need for Big Data technologies also rises. Apache Hadoop is the base of many big data technologies. Many Big data technologies like Hive, Hbase are built on the top of Hadoop. The trends of Hadoop and Big Data are tightly coupled with each other. So, Big Data and Hadoop are having a promising future ahead and will not be going to vanish at least in the next 20 years.

6. Increasing demands for Hadoop Professionals

Apache Hadoop is one of the most promising technologies that can handle rising Big data. Hadoop is an economical, reliable, and scalable solution to all the big data problems. With the increase in Big Data sources & the amount of data, Hadoop has become the most prominent Big Data technologies. This rising attributes demands for Hadoop professionals.

Big Companies like Walmart, Facebook, LinkedIn, eBay, etc are looking for Hadoop professionals. Thus there are rising needs of Hadoop professionals around the globe. The number of Hadoop jobs is increasing rapidly. So learning Hadoop gives you a tremendous opportunity to grab jobs across the globe.
