Shell Scripting

A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. It is a program to write a series of commands for the shell to execute.

Bash scripts can be used for various purposes, such as executing a shell command, running multiple commands together, customizing administrative tasks, performing task automation etc. …


AWS (Amazon Web Services) is a comprehensive Cloud Computing platform developed by Amazon, that provides a varied stage of services like Platform as a Service (PaaS), Software as a Service (SaaS), Networking as a Service (NaaS), and much more. Clubbed together with organizational tools like instance resources, database, storage and cloud front, AWS emerges as a full-end package in itself.

The other way round, Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. Its a wide-ranging branch of computer science concerned with building smart machines capable…


Whenever there’s a possibility of automation, even for single and simple things, there comes along lots of tools and processes that can be utilized and get the use-case concluded. However, using a single tool for complex pipelines may lead to intensive silos — even automation might consume good weight of resources. So what’s the explication? Yes, integration! An amalgamation of technologies no doubt simplify the process of tracking down the pipeline and implementing the same efficiently and painstakingly.

A big YES — if and only if the integration is substantial enough. Tweaking of anything can be done with anything, but…


Pokémon Go!

Everyone must have played or heard about Pokémon Go that boomed in the year 2018. Here’s the story about how they managed their servers without crashing or causing any delays to the huge incoming traffic that they received. But before starting, this story I would like to give a brief description about what Kubernetes is and what it is used for.

What is Kubernetes?


Hearing industry-experienced experts live is an absolute amaze to any learner. I am extremely grateful after I was able to witness an exclusive EXPERT SESSION : Industry Use-Cases with Demonstration of Kubernetes and gather the lifetime venture on why Kubernetes is an important aspect of DevOps and how it comes to work in real-time production environment.

The session was taken over by Mrs. Preeti Daga, Operations Manager, LinuxWorld Informatics Pvt. Ltd; technically headed by world record holder Mr. Vimal Daga, CTO, LinuxWorld Informatics Pvt. Ltd. and organized under the roof of LinuxWorld Informatics Pvt. Ltd.

  • Mr. Neeraj Bhatt (Senior Technical…

Life is all about gathering experiences — One who succeeds in implementing them practically, wins!

I am sure maximum of you will second to the fact that gaining only knowledge is never the utter route towards mastering a concept, essence of the technology can be grasped only if we go through the need for that technology in working Industry and the backlashes that can be solved the technology on runtime. And who can dictate these industry use-cases most precisely? Industry Experts obviously!

Recently, I am under a training session by LinuxWorld Informatics Pvt. Ltd., and the recent technology that’s been…


Ansible — Configuration Management Tool
Docker — Container Management Tool
Let’s integrate these two to come-up with a wonderful use-case!

What is Docker?

Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. While containers as a concept have been around for some time, Docker, an open source project launched in 2013, helped popularize the technology, and has helped drive the trend towards containerization and microservices in software development that has come to be known as cloud-native development.


HAProxy on AWS

Well, this practical’s gonna be a little much high-level and conceptual, so at first, let’s have a look at the concepts and ansible features that would be required further in the course of work.

In computing, load balancing refers to the process of distributing a set of tasks over a set of resources, with the aim of making their overall processing more efficient. A load balancing algorithm is “static” when it does not take into account the state of the system for the distribution of tasks. Unlike static load distribution algorithms, dynamic algorithms take into account the current load of…


Integration of AWS with Ansible

When automation comes into play, all we need is just one command and a whole webserver with a running webpage is deployed on the top of AWS cloud!!

Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. It runs on many Unix-like systems, and can configure both Unix-like systems as well as Microsoft Windows. It is managed primarily by Redhat and uses Python as the backend.

Unlike most configuration-management software, Ansible does not require a single controlling machine where orchestration begins. Ansible works against multiple systems in your infrastructure by selecting portions of Ansible’s inventory, stored as edit-able, version-able ASCII text files. Not only is this inventory configurable, but you can also use multiple inventory files at the same time and pull…


Industrial use-case session (RH294)

As technology advances, it reverses the characteristics of every situation again and again. The age of automation is going to be the age of ‘do it yourself.’
— — Marshall McLuhan

Being under the RH294 — Automation Using Ansible training from RedHat by LinuxWorld Informatics Pvt. Ltd., guided by the World Record Holder, on and only Mr. Vimal Daga Sir, and coordinated by Mrs. Preeti Chandak Daga Ma’am, I was one of those few students who got an opportunity to be a learner of the most exciting 2.5 hours of live practical demo on Ansible on 28th of December, 2020.
