If you are planning to create high-quality software, you should know about DevOps.

What exactly is DevOps? DevOps is a cultural and workplace movement that has defined how people in the technology industry conduct their business, iterate on features, and collaborate.

As companies today need to survive in a fast-paced environment, the DevOps software delivery strategy has been adopted for developing high-quality and controllable software.

What Is DevOps?

DevOps is a two-word combination, one for software development and the other for operations. It allows the team to manage the entire program lifecycle, from development to testing, implementation, and operation. DevOps helps reduce the gap between developers, system administrators, and quality assurance (QA) engineers.

Why Is DevOps Important?

Before we move further in the DevOps tutorial, let us understand why DevOps is needed when compared to other methods.

  • Without DevOps, team members spend a lot of time testing, building, and deploying rather than creating a project.

  • Deploying code manually causes a human error during production.

  • Development and operational teams have their schedules and do not coordinate, resulting in delays.

DevOps Automation Tools

A quick glance at DevOps Automation tools in our DevOps tutorial.

Automating and configuring all test processes is critical to achieving speed and flexibility. This process is known as DevOps Automation.

The difficulties faced by the DevOps team that manages a large-sized IT infrastructure can be broken down into six different categories.

  • Infrastructure Automation

  • Configuration Management

  • Deployment Automation

  • Performance Management

  • Log Management

  • Monitoring

Some Popular DevOps Tools – You must Know About

In this DevOps tutorial, let us look at some popular DevOps tools

Nagios

Nagios is a monitoring tool that monitors applications, servers, and the entire business infrastructure. This tool is very useful in large organizations with many circuits (routers, servers, switches, etc.).

Chef

This tool is used to check ubiquitous configurations and helps automate the infrastructure.

Jenkins

This is an open-source tool written in Java and is also an automation server. This helps to automate, build, and implement in multiple projects.

Docker

Docker is a lightweight tool designed to simplify and speed up various SDLC workflows through an integrated approach.

Puppet

An open-source tool for configuration management that automates how software is tested, deployed, and managed throughout its lifecycle, regardless of platform.

Ansible

Ansible is the open-source DevOps tool that offers one of the easiest ways to automate your IT applications and infrastructure, including cloud deployment, network configuration, and development environment creation.

DevOps Lifecycle

Learn about DevOps lifecycle steps and their stages in this article - ‘DevOps tutorial’.

DevOps aims to bring together all the people involved in IT development, operations, and infrastructure, including developers, testers, system administrators, and QA, under one roof. For this reason, all these people are collectively referred to as DevOps engineers.

DevOps engineers share the responsibility of gathering information, setting up infrastructure, developing, testing, implementing, continuous monitoring, and getting feedback from end-users. This process of development, testing, implementation, and monitoring is repeated to achieve better results.

Steps Of DevOps Lifecycle

  • Code

  • Build

  • Test

  • Release

  • Deploy

  • Operate

  • Monitor

  • Plan

Different DevOps Lifecycle stages

  • Continuous Development

  • Continuous Integration

  • Continuous Testing

  • Continuous Monitoring

  • Virtualization and Containerization

DevOps Benefits

We have seen many things about DevOps, now let see its benefits in this DevOps tutorial.

Following the successful implementation of the Software Development Life Cycle (SDLC), DevOps is now considered the key to accelerating various cloud platforms.

DevOps is a modern approach that allows companies to reap many benefits.

Some of the important benefits of DevOps are:

  • Breaking Silos

DevOps breaks the traditional department style, which means each task is assigned to a specific team and is essentially a silo. This in turn reduced flexibility. DevOps promotes communication and cooperation between teams.

  • Continuous Improvement

DevOps values continuous improvement by combining business and IT. It aims to shorten the feedback and delivery cycles which in turn results in customer satisfaction.

  • Minimized Failures

When companies use DevOps with error-detecting techniques, it significantly reduces the number of errors.

  • Innovation and Creativity

DevOps teams create a culture of trust and collaboration to improve their products/services by constantly creating innovative things.

  • Performance-oriented Culture

With DevOps, companies become more focused on performance. As a result, employees are more creative and efficient.

Roles Of DevOps Engineer

Here's a list of DevOps Engineer roles and responsibilities you'll need to advance your career.

  • Project Planning - DevOps engineers are an integral part of project planning.

  • Product Development - Responsible for the development, design, and management of IT solutions.

  • Product Deployment - Create and build automated deployment schemes using configuration management technologies.

  • Performance management - Evaluate existing applications/platforms and provide recommendations for improving performance.

  • Troubleshooting and Maintenance - Define the requirements and procedures for regular supervision with the help of a strategy-building method.
