DevOps For Beginners

Introduction

DevOps is one of the most trending technologies in the digital market. In the early stages, it was a combination of two words “development” and "operations," but now it has evolved into various tools, frameworks and methodologies which help in automating multiple processes. DevOps facilitates continuous development, deployment, monitoring and testing. It increases business value by accelerating product delivery time. This article will help you to understand DevOps concepts from basics to advanced level with real-time examples.

Overview Of DevOps

DevOps is an emerging field that seeks to bring together developers, operations and other IT teams to work as one cohesive unit. This can be seen as a response to the disconnect between the two groups that were previously responsible for different aspects of software development—one creating it, the other maintaining it.

The idea of DevOps was first introduced in 2009 by Patrick Dubois at Gartner's Symposium on Software Operations Management (SSOM). He believed that organizations could benefit from integrating development and operations into an improved workflow where they collaborate more effectively with each other while achieving goals faster than before.

Much like agile software development methodologies, DevOps also aims to streamline processes through automation and continuous improvement. It encourages close communication among team members throughout every step of production; from coding new features or fixing bugs to testing them out, deployment onto production servers, monitoring performance metrics, and identifying issues with those metrics so that action can be taken timely enough so as not result in downtime for users who rely upon those services.

DevOps Tools

As a beginner, you should also be familiar with the following tools;

Git – Version control system. A platform for collaboration and sharing code among multiple developers. Git is a popular open-source tool that helps organizations manage their source code in a centralized manner. It allows teams to track project changes, collaborate over the internet, and deploy updates to production more efficiently.

Jenkins – Continuous integration server with an extensible plugin system. Jenkins is used by many companies as a continuous integration (CI) server because it is easy to configure and use, has an extensive library of plug-ins to customize its features, and integrates easily with other software development tools such as GitHub or Hudson.

Docker - Container runtime environment that packages software in virtual containers that can run on any infrastructure without dependencies on things like the operating system or libraries that may not be available inside those environments (for example, Windows). Docker provides portability across different operating systems by running applications inside containers instead of installing them directly onto servers where they might rely on specific versions of libraries or dependencies from one particular operating system instead of another one; hence “universal application runtime environment” which means you can run your application anywhere there's Docker support regardless if both hosts have identical configurations!

Ansible - Configuration management tool written in Python used primarily for automating deployments but also anything else IT operations related like configuration management itself (i.e. package installation), etc.

Terraform - Infrastructure construction platform built atop providers like AWS Cloud Formation which manages infrastructure provisioning during Software Development Lifecycle stages such as DevOps practices like Continuous Delivery/Continuous Deployment (CD/CD), Continuous Integration(CI), etc.

Chef - Infrastructure automation framework using Ruby language-based scripts written by Ops engineers who write recipes describing how each application component should be configured before being deployed into production environments, these recipes are then parsed into commands using Chef Client which runs against target nodes managing those resources accordingly…

Puppet Master - A centralized server where all configurations reside centrally rather than locally.

DevOps Training

DevOps training is a combination of software development and operations training. If you are in either role, then DevOps is for you. DevOps as a concept has been around since the early 2000s, when developers and IT operations people began working more closely together to improve both processes and culture across organizations. It has proven so useful that many companies have adopted it into their daily routines, with some even going so far as to hire entire teams of "DevOps engineers" who coach others on how best to implement these practices.

Why DevOps

DevOps is a set of practices that help you to deploy software more frequently and with more confidence. It is not a tool, it's a cultural change.

The goal of DevOps is to improve communication between development and operations teams by removing the barriers between them. This can be accomplished by using automation where possible, especially when deploying new features or releases.

DevOps is also known as CI/CD (Continuous Integration/Continuous Delivery). In the software world, CI/CD pipelines refers to automation that enables incremental code changes from a developer's desktop to be delivered swiftly and reliably to production.

DevOps is a software development practice that aims to improve communication and collaboration between software developers and IT operations professionals by automating the process of software delivery. It is also described as a culture, movement or philosophy.

A combination of cultural, organizational, and technological practices that help an organization deliver applications in a more effective manner through improved collaboration between development and operations (DevOps) teams. It aims to reduce the gap between both these departments. It requires software development changes like agile methodologies, continuous integration, open source technology tools etc, while it also requires business process changes like cross-functional teams (i.e. DevOps team), tighter project governance just to mention a few.

Conclusion

DevOps has become the latest buzzword in IT, and it is for good reason. DevOps is vital to effective IT communication, collaboration, and productivity. In fact, big tech companies like Netflix have adopted it as a core part of their business model. If you’re looking to move forward with your career or boost your team’s performance at work, then look no further than DevOps. It will be a step in the right direction.
