Hadoop As Big Data

Introduction:
In this blog, I will discuss Big Data, its characteristics, different sources of Big Dataand some key components of Hadoop Framework.
In the two part blog series, I will cover the basics of Hadoop Ecosystem.
Let us start with Big Data and its importance in Hadoop Framework. Ethics, privacy, security measures are very important and need to be taken care while dealing with the challenges of Big Data.

Big Data: When the Data itself becomes the part of the problem.
Data is crucial for all organizations. It has to be stored for future use. We can refer the term Big Data as the data, which is beyond the storage capacity and the processing power of an organization.

What are the sources of this huge data?
There are different sources of data such as the social networks, CCTV cameras, sensors, online shopping portals, hospitality data, GPS, automobile industry etc., that generate data massively.
Big Data can be characterized as:
  • The Volume of the Data
  • Velocity of the Data
  • The Variety of Data being processed
Volume of Data à Data is increasing rapidly in GB, TB, PB and so on, and requires huge disk space to store it.
Velocity of Data à Huge Data is stored in Data Centres to cater to the organizational needs. In order to get data to the local workstation high-speed data processors are needed.
Variety of Data à Data can be broadly classified into the following types-Structured, Unstructured & Semi structured.
Big Data = (Volume + Velocity + Variety) of Data

Machine Learning & Deep Learning

Machine Learning & Deep Learning Understanding the latest advancements in artificial intelligence can seem overwhelming, but it really boils down to two concepts you’ve likely heard of before:  machine learning  and  deep learning . These terms are often thrown around in ways that can make them seem like interchangeable buzzwords, hence why it’s important to understand the differences. And those differences should be known! Examples of machine learning and deep learning are everywhere. It’s how Netflix knows which show you’ll want to watch next or how Facebook knows whose face is in a photo. And it’s how a customer service representative will know if you’ll be satisfied with their support before you even take a customer satisfaction (CSAT) survey. So what are these concepts that dominate the conversations about artificial intelligence and how exactly are they different? What is machine learning? Here’s a basic definition of machine learn...

Data Engineering - Tools & Intro

Data Engineering - Tools & Intro So I just realized that I am here after a month or so. I was busy at work and traveling. I am starting a kind of new series, I say it Data Engineering Series in which I will be discussing different tools. Of course, I am not able to discuss the entire concept of Data Engineering neither I know it as I will be learning myself. What is Data Engineering? Data Engineering is all about developing, maintaining systems that are responsible for transferring data in large volumes and make it available for analysts and data scientists to use it for analyzing and data modeling. Data engineering is a superset of Data Science or the subset, not clear to me but the collaboration of data engineers and scientists fruits useful data-driven solutions. Data Engineering tools It consists of several tools. Some are dealing with data storage while others with analysis and ETL. Ofcourse, Apache Kafka is one of them. The others tools that I might be covering are Apache...
