Introduction to Puppet: A Comprehensive Guide for Configuration Management What is Puppet? Puppet is an open-source configuration management and deployment tool that allows IT administrators to automate infrastructure management. Puppet works by defining system configurations as code, ensuring that infrastructure remains consistent and predictable across multiple systems. This approach, known as “Infrastructure as Code” (IaC), enables teams to scale operations without a corresponding increase in manual effort. Puppet automates repetitive tasks such as installing and configuring software, managing system resources, and enforcing security policies. With its powerful and flexible framework,…

DevOps, a term derived from the combination of “Development” and “Operations,” is a software development philosophy that has significantly changed how applications are created and maintained. It represents a cultural shift in the way developers, IT professionals, and other stakeholders collaborate to deliver software in a faster, more efficient, and more reliable manner. DevOps is driven by the need for faster time-to-market, continuous software delivery, and improved collaboration across various teams involved in the software lifecycle. Understanding DevOps requires familiarizing oneself with a range of terms and practices. These terms…
