In any typical organization, the development team creates products, and the operation team manages and maintains these products. However, the DevOps concept is a collaboration between development and operation teams, which enables continuous delivery of applications and services to end-users.
This means that when the development team is ready with the product, it goes to the maintenance and management phases immediately and is released to the end-users with minimum delay.
According to InformationWeek, DevOps will be in high demand in the future with little chance of slowing down. The DevOps market will be worth USD 14.9 billion by 2026, a good sign that demand will remain consistently high.
But before we explore how to become a DevOps engineer, we need to address the question: “What is a DevOps engineer?”
What Is a DevOps Engineer?
A DevOps engineer is an IT professional who has an in-depth understanding of the software development lifecycle. They need to understand why the organization had to move from one model to the other, the shortcomings of the previous model, the benefits of the new model, and so on.
A DevOps engineer also must know how to use various automation tools for developing continuous integration and continuous deployment (CI/CD) pipelines. This demand position requires a special set of DevOps skills, which we will explore more in-depth later.
There are various stages in a CI/CD pipeline. The first stage is the planning stage, which includes writing an algorithm for your product. The next stage is the building stage, where the algorithm is transformed into a product that can be used.
The product is then tested in the testing stage where all bugs are found and corrected. The product finally goes to the deployment stage, where it’s introduced to the end-users. Once the product is deployed, it needs to be monitored continuously, which is a new concept recently introduced into the DevOps lifecycle.
DevOps engineers focus more on the monitoring stage compared to the previous stages. It's essential to monitor the product continuously to catch new bugs, fix them, and push the corrected version back to the client. This is done to ensure customer satisfaction once the product is deployed into the real world. DevOps engineers collaborate with the development and operation teams to deliver high-quality products in as short a time as possible.
A DevOps engineer can also venture down other career paths, such as:
- DevOps architect
- Automation engineer
- Software tester
- Integration specialist
- Security engineer
- Release manager

DevOps Engineer Roles and Responsibilities
A DevOps engineer works with both the development and operations teams to create and implement software systems. Therefore, they need to collaborate with software developers, quality assurance professionals, and other IT staff. A DevOps engineer’s main roles and responsibilities include:
- Write documentation for the server-side features.
- Develop, install, test, configure, and maintain IT solutions.
- Communicate operational requirements and development forecasts with everyone in the team.
- Develop plans and processes for improvement and expansion of the current technologies being used.
- Deploy updates automatically into the production environment using configuration management software.
- Perform routine application maintenance and troubleshooting measure to ensure the production environment runs smoothly.
- Perform gap analysis to identify performance enhancements, identify alternative solutions, and assist with modifications.
DevOps Career Path
Programming Language and Linux Fundamentals
It's also essential for a DevOps Engineer to know the fundamentals of the Linux Command Line Interface (CLI). The mandatory Linux skills that a DevOps engineer should have include:
- Linux shell - bash or ksh
- Linux commands - find, grep, awk, sed
- Networking commands - nslookup and netstat
Source Code Management
The next milestone for a DevOps engineer is to learn source code management. This is essential for keeping your projects organized, regardless of the number of code sets you have. Learn at least one of these standard source code management tools:
You can choose to start with any of these source code management tools. However, we recommend that you begin with Git. Git is used to tracking changes in the source code and can manage large projects efficiently. It also allows multiple developers to work together with ease.
A DevOps engineer needs to learn how to build an application and commit to the source code management tool. One of the most popular ways to make an application is by using Maven, an automation tool that helps build and manage software projects within a short period. Maven has a smooth build process, supports parallel builds, and provides instant access to new features with no additional configurations.
Automation with CI/CD Tool
You need a project object model (POM) file to build an application. The POM file consists of a set of jars, commands to be executed, the builds plugins, and builds profile.
DevOps engineers should use a continuous integration or continuous development (CI/CD) tool. There are plenty of CI/CD tools available, such as Jenkins, TeamCity, Drone, etc.
Jenkins is one of the most extensively used automation tools on the market. It's an open-source continuous integration tool, helping to automate the constant development, testing, and deployment of newly created codes. You should learn Jenkins because:
- It has multiple plugins
- It's easily distributed across multiple machines
- It’s easy to install and configure
Once you’ve completed the build process, you need to learn how to automate the web applications testing process. Selenium is one of the best testing tools for QA teams, providing fast execution, allowing scripting in several languages, and supporting parallel test execution.
Once the application is tested, it needs to be deployed and run in the production server. To deploy an application, you should know the relevant containers and configuration management tools.
Docker is a useful tool that helps to deliver software in containers. It has high scalability and efficiency, provides usable data volumes, and has isolated applications.
Ansible is an agentless configuration management tool. Unlike other tools in this field, it provides the capability of pushing configurations onto multiple servers and maintaining them in the required state. It uses SSH for secure connections.
Monitoring applications is another important aspect of a DevOps engineer. In this stage, any existing issues are identified, and changes are implemented quickly.
Nagios is a popular application monitoring tool that helps in comprehensive monitoring, has high availability, and provides immediate remediation.
A DevOps engineer needs to know about cloud service providers and their basic applications. Cloud computing is an important skill to learn, regardless of the field, you’re working in.
Amazon Web Services (AWS) is the most popular cloud provider in the industry today. Many companies keep their infrastructure on this cloud because it provides higher scalability, greater flexibility, and better security. It's comparatively more cost-effective than other cloud providers.
Other cloud providers, such as Microsoft Azure and Google Cloud Platform, are slowly catching up in terms of speed.
While learning how to become a DevOps engineer, you should also be aware of the salary prospects in the field. After all, if you plan on sticking with a DevOps career for the long haul, you should make sure it’s an economically viable choice, right? Check out the DevOps engineer salary in the following section.
