Big data and Cloud Computing

Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). It’s a virtualization framework.

It is like a resource on demand whether it be storage, computing etc. Cloud follows pay per usage model. You need to pay the amount of resources you use.

This computing service by cloud charges you based only on the amount of computing resources we use. So for example, if you want to give a demo to a client on a cluster of more than 100 machines and you do not have so many machines currently available with you, then in such case cloud computing plays a very important role.

Cloud plays an important role within the Big Data world, by providing horizontally expandable and optimized infrastructure that supports practical implementation of Big Data.

Hadoop for Data Science 

Looking for the answer to why you need to learn Hadoop for Data Science?  You landed on the right page.

Here you will find why Hadoop is must for the data scientist. At the end of this article, I will share a case study where you will learn how Marks & Spencer Company is using Hadoop for its data science requirements. So, without wasting the time let’s move on to the topic-

Currently, data is increasing at an exponential rate. There is a huge demand for processing a high volume of data. One such technology that is responsible for processing large volumes of data is Hadoop. Here is what exactly Hadoop Means –

What is Hadoop?

Apache Hadoop is open-source software that facilitates a network of computers to solve problems that require massive datasets and computation power. Hadoop is highly scalable, that is designed to accommodate computation ranging from a single server to a cluster of thousands of machines. While Hadoop is written in Java, you can program in Hadoop using multiple languages like Python, C++, Perl, Ruby etc.

The concepts of Big Data like MapReduce became a widespread phenomenon after Google published its research paper that also described its Google File System.

There are three main components of Hadoop –

Hadoop Distributed Filesystem – It is the storage component of Hadoop. Hadoop is a collection of master-slave networks. In HDFS there are two daemons – namenode and datanode that run on the master and slave nodes respectively.

Map-Reduce – This part of Hadoop is responsible for high-level data processing. It facilitates processing of a large amount of data over the cluster of nodes.

YARN – It is used for resource management and job scheduling. In a multi-node cluster, it is difficult to manage, allocate and release the resources. Hadoop Yarn allows to manage and control these resources very efficiently.

What is Data Science?

Data Science is the study of data. It is about finding patterns in data through an in-depth analysis.

 The process of Data Science involves the extraction, data transformation, data analysis and prediction to gain insights about the data. With Data Science, employees can assist in the decision-making process which will help the business to grow and enhance the quality of the product.

Data Science is the most sought after field today. Data is everywhere. It is being generated at an exponential rate and contains within insights that can shape the course of businesses.
