A series of articles dedicated to Big Data analytics and Data Engineering. All codes and exercises of my blog are hosted on GitHub in a dedicated repository :
I’ll start by introducing really general articles :

Useful Bash commands : A quick recap of useful Bash commands to interact with your Terminal.
Making your code production-ready : A quick overview of nice tools to improve the quality of your code before production !
Introduction to Hadoop : In this article, we’ll cover the basics of Hadoop, a quick history, and an overview of the main features of Hadoop.
MapReduce : MapReduce is a programming paradigm that allows to process a large amount of data by initially splitting the data into blocks, sending the blocks to different clusters to perform operations, and aggregating the results.
HDFS : HDFS stands for Hadoop Distributed File System. It is a sub-project of Hadoop. HDFS lets you connect nodes contained within clusters over which data files are distributed, overall being fault-tolerant.
VM’s in Virtual Box : Hadoop runs only on GNU/Linux platforms. Therefore, if you have another OS, you need to install Virtual Box. Virtual Box is a software that lets you create and run Virtual Machines.
Hadoop with the HortonWorks Sandbox : The Sandbox by Hortonworks is a straightforward, pre-configured, learning environment that contains the latest developments from Apache Hadoop, specifically the Hortonworks Data Platform (HDP).
Load and move files to HDFS : In this article, we’ll see how to download the input text file for our WordCount job, and put the file into HDFS.
Launch a Map Reduce Job : In this article, we’ll get to the core of the exercise : launch a MapReduce WordCount job.
MapReduce Jobs in Python : Using Hadoop Streaming, we can submit MapReduce Jobs in Python.
Execute MapReduce Job in Python locally : In this short article, we’ll see how to execute MapReduce Jobs using Hadoop streaming locally.
Introduction to Spark : Apache Spark is a unified analytics engine for large-scale data processing. It is overall much faster than Hadoop MapReduce, and widely used in the industry.
Install Spark-Scala and PySpark : In this quick tutorial, we’ll cover installation techniques for the 2 most popular APIs of Spark.
Using Spark-Scala for Machine Learning : A dive into Spark-Scala for Machine Learning through examples.
How to install (py)Spark on MacOS (late 2020) : Installation guide step by step in 3 minutes :)
Cloud Concepts : What is Cloud Computing ? What are the main concepts behind it ? This article is part of the AWS Cloud Practioner certification.
Core Services : What are the core services of AWS and other Cloud providers ?
TPU survival guide on Google Colaboratory : TPUs are changing the way we are training Neural Networks. Developped by Google, TPUs have a different way to perform matrix operations and are optimized for certain tasks. We’ll cover the basics of TPU computation, and how to use them in Colab.
Using Google Drive to save and load files in Colab : Google Colab offers CPUs, GPUs and TPUs for free. It’s a great tool for any project, but you need to have your files uploaded on Google Drive. We’ll see how to interact with Google Drive from Colab.
Deploy a container on GCP : A simple step by step tutorial on how to deploy a container on Google Cloud Platform.
