In any typical business in any typical organization, the development team develops products, and the operations team is responsible for maintaining and managing the products. But it is the DevOps idea involves collaboration between development and operations teams, that allows continuous delivery of software and services to users.
That means that once you know that development team is prepared with the software, it moves into the management and maintenance phases right away and then is released to users with the least amount of delay.
As per InformationWeek, DevOps will be in high demand in the near future with no chance slowing down. The DevOps market is expected to be valued at USD 14.9 billion in 2026. an indication that the demand for DevOps will continue to be high.
However, before we consider the steps to becoming an DevOps engineer, we must to answer the question: "What is a DevOps engineer?"
What is an DevOps Engineer?
The DevOps engineer will be an IT professional with an knowledge about the entire software development process. They must be aware of the reasons the company needed to change between one and another and the flaws of the old model, and the advantages that the model has to offer and so on.
The DevOps engineer should also be aware of how to utilize different automation tools to create continuous integration as well as continuous deployment (CI/CD) pipelines. This position of need needs a particular combination of DevOps abilities that we will investigate more deeply further down the line.
There are many stages to the process of CI/CD. The first is planning which involves the creation of the algorithm to your solution. The next step is the building phase in which the algorithm is turned into a product that is able to be utilized.
It is tested during the testing stage , where every bug is identified and rectified. The product then moves to the deployment phase, which is when it's presented to customers. When the product is installed it has to be continuously monitored This is a novel concept that has recently been introduced into the DevOps lifecycle.
DevOps engineers concentrate more on the monitoring stage as compared to previous stages. It's crucial to monitor the software continuously in order to spot new bugs, correct them, and then push the correct versions back into the user. This helps ensure customers are satisfied when the product is released into the world. DevOps engineers work with development and operations teams to provide top-quality products in as little an amount of time as is feasible.
A DevOps engineer may also go in other directions like:
- DevOps architect
- Automation engineer
- Tester of software
- Specialist in integration
- Security engineer
- Release manager

- Git
- CVS
- Mercurial You may begin with any of these tools for managing code. We suggest you start with Git. Git is utilized to monitor changes to the source code and to handle large projects with ease. It also allows developers to work effortlessly.
Application Building
An DevOps engineer should understand how to create an application, and then commit it to the software for managing source code. The most well-known methods of creating an application is to use Maven, an automated tool that allows you to develop and run software development projects in the shortest time. Maven is a fast process of building allows parallel builds and allows quick access to new features without any additional configurations.
Automation through the CI/CD Tool
You require an application object model (POM) file in order to create an application. The POM file is comprised of the jars that are used and commands to be executed as well as the build plugins and the profile of the build.
DevOps engineers must use continuous integration (CI) or development (CI/CD) software. There are a variety of tools for CI/CD, like Jenkins, TeamCity, Drone and many more.
Jenkins is among the most frequently utilized automation tools in the market. It's an open source continuous integration tool that helps to automate the continuous development of testing, development, and deployment of new software. You must be familiar with Jenkins for the following reasons:
- It includes numerous plugins
- It's easy to distribute across many machines.
- It's simple to install and set up.
Testing of Applications
After you've completed the construction process, you'll have to understand how to automate the web tests for your application. Selenium can be considered to be one of the most effective tools for testing QA teams. It provides speedy execution, scripting support in multiple languages, and that allows parallel execution of tests.
Application Deployment
After the application has been verified, it has to be installed and run on the server that runs production. In order to deploy the application, you need to know the pertinent containers and the tools for managing configurations.
Docker
Docker is an efficient tool that assists in delivering software within containers. It is highly scalable and effectiveness, can provide large amounts of data that can be used, and can be used for isolated applications.
Ansible
