Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, intraservice orchestration, and provisioning. Automation is crucial these days, with IT environments that are too complex and often need to scale too quickly for system administrators and developers to keep up if they had to do everything manually. Automation simplifies complex tasks, not just making developers’ jobs more manageable but allowing them to focus attention on other tasks that add value to an organization. In other words, it frees up time and increases efficiency. In simple words, Ansible is a configuration management tool that is used to manage different servers at the same time. Why industry use Ansible? Ansible requires no additional agents or security infrastructure and can be used for multi-...

  What is LVM? LVM is a tool for logical volume management which includes allocating disks, striping, mirroring and resizing logical volumes. With LVM, a hard drive or set of hard drives is allocated to one or more physical volumes. LVM physical volumes can be placed on other block devices which might span two or more disks. What is Hadoop? The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures. Let's get started: First launch an instance in AWS and configure it as Master launch an instance in ...

What is Docker? Docker is a set of the platform as 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.  Let's get started: Install & Run Docker Container in your Linux Terminal. 1. Go to link copy this link. 2. Go inside directory  `/etc/yum.repos.d/` 3. Create a file named `docker.repo` 4. Inside docker.repo write the following 👇 5. Save the file. Now install Docker using the command  yum install docker-ce --nobest --allowerasing Docker is successfully installed, now we need to check  Docker service is started or not. To check Docker service is started or not use command systemctl status docker If it shows inactive ( dead ) like image above 👆 then we need to start service. To start Docker Service use command systemctl start docker...

  Hello everyone,  In this blog, you will find a detailed explanation of creating a High Availability with AWS CLI. Prerequisites: Create an AWS account. Install AWS CLI in Windows. Configure AWS CLI with IAM user. What is AWS CLI? The AWS Command Line Interface (CLI) is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts. The AWS Command Line Interface (AWS CLI) is an open-source tool that enables you to interact with AWS services using commands in your command-line shell. With minimal configuration, the AWS CLI enables you to start running commands that implement functionality equivalent to that provided by the browser-based AWS Management Console from the command prompt in your terminal program What is AWS S3 service? Amazon Simple Storage Service is storage for the Internet. It is designed to make web-scale computing easier for...
