Hello Everyone!!!

I hope you all are fine and healthy. I guess you are here to learn about openshift and where it has been used to solve the problem and benefit the industry. So let's get started.

First, let’s talk about what is openshift and why we need it. Let me tell you in very short. We all have been using a system to do our tasks. We are using the OS on top of bare metal. In industry, they use the concept of containerization there; the application is packaged with the library, framework, and configuration files required to run…


Neural Network and its Use Cases in Current IT Industry

Greeting Everyone!!! Herewith another blog on Neural Network's information and their current use cases in the IT Industry affected our lifestyle.

We all have used computers, and we have seen how much power they are. Computers are capable of doing many things that a human brain finds difficult or time taking. They are not smart, but they are faster than a human brain. Computers are built and programmed and designed by humans to make the task faster. We can say that computers are just designed and developed to do a certain programmed task. What if computers start working as a…


Writing a playbook to make HTTPD service Idempotence dor utilizing Computer Resource properly.

Greetings Everyone!!! I hope you all are fine and doing well.

In this blog, we will be creating an Ansible Playbook that will help us install HTTPD in a system and run the service idempotence when the playbook is running again. If you need some insight related to Ansible, you can check this blog.

So let’s get started with the task…

STATIC PLAYBOOK

First, let’s write a simple and static playbook that will install and start the “httpd” service. We will observe why we cannot get Idempotence Nature with HTTPD with a simple and regular setup.

Below is the code from my…


Ansible playbook is written to configure Name Node and Data Node in Hadoop and Start the Cluster.

Greetings Everyone!!! I hope you all are having a great day.

Let me start by explaining Ansible. In short, the word you need to understand that Ansible is a powerful automation tool for configuration. We have to download and set 100 and 1000 systems servers at the industry level to provide smooth service. Configuring one by one and manually is not a good way. Hence, we have some tool by which we need to write some predefined code as per our need and run it one system, and the whole cluster of systems gets configured. Ansible is among one of…

Creating a network Topology Setup in such a way that System A can ping to System B and System C, but both these systems cannot ping each other.

Hey guys. I hope you all are doing well and fine.

This blog is about how we can customize our networking in our system as per our requirement. This is Part 2. You can check out Part 1 in my previous blog.

Here we will have three systems, i.e., System A, B, and C. We will create a network rule so that System A can ping B and C and vice versa, but System B and C won't be able to ping each other. Our finding will be how two systems (B and C) can ping another system(A) and vice…

INTRODUCTION

We haven’t imagined, and many are still unaware that we can launch an OS in just a command and a few seconds. Yes, it is possible due to container technology.


How Hadoop works and how it handles data node failure during file transfer.

Greeting Everyone!!! I hope you all are having a good day.

“The world is one Big Data Problem” ~ Andrew McAfee

Here in this blog, we will discuss how Hadoop Cluster is created and how we transfer data in the cluster and retrieve it. Lastly, what will happen when a data node (system holding data) crashes while we are retrieving the data. So, let’s get started…..

For the Hadoop Cluster creation part, please refer to my previous blog where I have explained how we can create a Hadoop Cluster consisting of Name Node, Data Node, and Client Node.

Our second…
