In this blog, I would like to contribute specific amount of storage in slave node to the Hadoop Cluster,. And the Hint is “ Linux Partitions ”..
🤔 Can we solve this situation using Linux Partitions ?
Yes, we can do this by using the concept of LVM ( Logical Volume Manager )
❓ What is LVM ( Logical Volume Manager ) ?
LVM, or Logical Volume Management, is a storage device management technology that gives users the power to pool and abstract the physical layout of component storage devices for easier and flexible administration. …

📝 Task Description: Write an Infrastructure as code using terraform, which automatically create a VPC.
✅ In that VPC we have to create 2 subnets:
1. public subnet [ Accessible for Public World! ]
2. private subnet [ Restricted for Public World! ]
✅Create a public facing internet gateway for connect our VPC/Network to the internet world and attach this gateway to our VPC.
✅ Create a routing table for Internet gateway so that instance can connect to outside world, update and associate it with public subnet.
✅ Create a NAT gateway for connect our VPC/Network to the internet world and attach this gateway to our VPC in the public network
✅ Update the routing table of the private subnet, so that to access the internet it uses the nat gateway created in the public subnet
✅ Launch an ec2 instance which has Wordpress setup already having the security group allowing port 80 so that our client can connect to our wordpress site. Also attach the key to instance for further login into it. …

Today, I would like to share my journey of RedHat Ansible training under the mentor Mr. Vimal Daga sir …
Actually, this training s about 30 days, but he finished in 22 days from basic to very advance level… The way he teaching will fill the confidence with in us to do the complex things in a simple manner … And he proved that, “None of the technology is difficult to learn because it is created by human” ….
What I have learnt during these 22 days ~
Introduction to Ansible
🔅Provision EC2 instances through ansible.
🔅 Retrieve the IP Address of instances using the dynamic inventory concept.
🔅Configure the web servers through the ansible role.
🔅Configure the load balancer through the ansible role.
🔅The target nodes of the load balancer should auto-update as per the status of web servers.
🏃 Follow the below steps:
Step 1: Install boto and boto3 libraries..
pip3 install boto
pip3 install boto3
Step 2: Write the ansible code to launch 4 EC2 instances namely web1, web2, web3 and LB… Here is the code ~
- hosts: localhost
— variables.yml vars:
Netflix is the world’s leading internet television network, with more than 100 million members in more than 190 countries enjoying 125 million hours of TV shows and movies each day. Netflix uses AWS for nearly all its computing and storage needs, including databases, analytics, recommendation engines, video transcoding, and more — hundreds of functions that in total use more than 100,000 server instances on AWS.
Daily, we are uploading photos and sending messages to our friends … Have you ever think about the data where it gonna storing all these things. Or, How Face Book is managing (saving and retrieving) the data within seconds …
What is big data ? Why Big Data problem arises ? How Facebook is managing thousands of tera bytes of data ? Which technology Facebook is using to managing those data ? Let’s see solution for all these questions …
🤔 Why the Big Data problem arises ❓
There is a huge explosion in the data available. Look back a few years, and compare it with today, and you will see that there has been an exponential increase in the data that enterprises can access. This data exceeds the amount of data that can be stored and computed, as well as retrieved. The challenge is not so much the availability, but the management of this data. With statistics claiming that data would increase 6.6 times the distance between earth and moon by 2020, this is definitely a challenge. …
Here is my second task given by Vimal Sir in the RedHat Ansible training program … In this task, I’m going to configure webserver on the top of AWS Instance using Ansible tool …
📝 Problem Statement : Deploy Web Server on AWS using ANSIBLE
✅ Provision EC2 instance through ansible.
✅ Retrieve the IP Address of instance using dynamic inventory concept.
✅ Configure the web server through ansible! by copying the webpage to /var/www/html/ directory .
Let’s solve this case step by step …
Step 1: For launching Instance on AWS Cloud from localhost, we have to install library for ansible to contact with AWS EC2 instance… For this install boto library using pip3 command…
😊 Hello Everyone,
✨ In this post, I would like to share the practical what I have done in Two days Workshop under the guidance of Vimal Daga sir…
😎 Vimal sir given a task which is a industry level use case… Take FB as an example, we have used it so many times. But we don’t know where it stores our data and where the webapp / webserver is running … Assume that for webapp FB is using wordpress and for storing the data it is using MySQL.. …
