10 Must-Have Skills for a DevOps Engineer in 2025

They should also know how to execute tests for an entire DevOps automation pipeline and how to integrate Jenkins with Selenium. As a DevOps Engineer, you need to be skilled in the following; cloud computing, containerization, automation, scripting, CI/CD, infrastructure as code, and more. We encourage you to read the full article to learn more about these skills and why they are important.

Bug Reduction of DevOps

Understanding proactive monitoring is part of a DevOps engineer’s job. They must know how to use monitoring tools like Nagios and Splunk, and they should also be able to recognize bottlenecks in the production system, apply security patches, and upgrade system versions. DevOps engineers should know Node.js and programming languages like Java, Javascript, Ruby, Shell, Bash and PHP. A DevOps engineer must understand Linux fundamentals, such as file handling, system administration, text processing, and process management. They should also know how to operate Linux servers and be proficient in scripting languages, such as Python.

• DevOps is not just about tools and processes; it’s also about people and how they work together.
• The position requires technical and interpersonal skills so you can liaise between multiple departments.
• This phase includes the application’s programming, where developers code, test, and build new, enhanced features.
• The code integrates with existing platforms such as Microsoft Exchange, Redis, database systems, or countless other third-party or open source business applications that use common APIs.

What Certifications Help You Become a DevOps Engineer?

You can demonstrate your understanding of containerization tools by creating a simple project with frontend and back deployed as two separate containers. If you have already developed these components in the previous stages of the roadmap, re-use them to save time. Version control systems like Git make it easier for developers to track changes in their source code by maintaining a history of the changes. Combined with platforms like GitHub or Bitbucket, Git can facilitate developers to work collaboratively with each other. To demonstrate your understanding of Python, you can create a web scraper (or other coding projects) that extracts a list of hotels, their address, prices, reviews, and locations from a site like booking.com.

What are the core principles of DevOps?

Become an invaluable resource to your company by acquiring development and engineering skills through Udemy’s online courses. DevOps engineers can start with an entry-level system administrator, support, or help desk role to gain experience with software maintenance. Applications rely on multiple containers that communicate with each other. To facilitate the orchestration of these containers, you can use container orchestration tools like Kubernetes. The Docker Roadmap provides essential resources to help you master Docker and Kubernetes.

DevOps tools for the whole team

An application developed by one developer may not work on other machines due to the difference in environment. To eliminate this issue, DevOps engineers use containerization tools like Docker. A DevOps engineer should have a sound knowledge of web servers like Nginx. Nginx allows you to serve your application on the web while handling reverse proxy and load balancing. Once you go through the tutorial, you can easily switch from Bitbucket to GitHub and GitLab, which are more popular among developers. Some programs and packages may not have a GUI counterpart, and even when they exist, using the CLI(Command Line Interface) alternative is faster and easier to automate.

It helped in the close collaboration of development and operations teams all the way through the software development life cycle. DevOps Middle+ DevOps Engineer job engineers typically work closely with development teams throughout the software development lifecycle (SDLC) of a given application or service. Automating build systems, deploying and running CI/CD infrastructure, and monitoring critical production applications are just some of the jobs they are tasked with.

DevOps Engineer Job Tasks

At the same time, they bring the critical elements of continuous integration and continuous deployment to the DevOps engineer’s sole responsibility. Due to its enormous potential benefits, many organizations encourage employees to take a DevOps Course to implement these practices in their day-to-day activities. According to a report by NASSCOM, India’s IT sector is expected to grow 7.7% in FY2021, which will create more jobs for DevOps engineers. Within this industry, DevOps engineering is one of the fastest-growing domains due to its critical role in software development processes. Shift-left is a software development practice that involves moving tasks and processes earlier in the development lifecycle. By shifting tasks left, teams can identify and address issues earlier in development, reducing the cost and effort required to fix them.

• They also use infrastructure as code (IaC) to programmatically create infrastructure from code such as scripts.
• They also provide the bridge needed to facilitate those releases on the operations side.
• As a cloud architect, you will develop and design cloud applications and networks, oversee cloud-based applications, and optimize or troubleshoot when needed.
• Understanding how these tools work under the hood will allow you to troubleshoot faster and even add more features to your tools.
• Many of these programs are offered by accredited institutions, so be sure to do your research before enrolling.
• But continuous improvement extends to the contributor level as well; continuously improving and developing soft skills help drive high performance DevOps across an entire organization.

Advantages of DevOps

• Cloud-native technologies like service meshes and serverless frameworks continue evolving.
• To become a DevOps consultant, focus on obtaining a relevant education and gaining hands-on experience with key DevOps tools and technologies.
• Serverless computing, such as AWS Lambda, eliminates the need for DevOps engineers to manage infrastructure.
• The DevOps lifecycle typically includes planning, development, testing, deployment, monitoring, and feedback.
• Containerization (or container technology) and orchestration help solve the issues of software deployment and resource utilization.
• If you’re keen on a career as a DevOps engineer, explore the following choices.

A DevOps engineer should also have a good grasp of all the parts of a delivery pipeline and know the pros and cons of available tools and Line code services. Also, it has several technical benefits, such as continuous delivery, early problem detection and correction, and easy project management. The business benefits from faster delivery, better management of KPIs, and better teamwork.

Consequently, many global enterprises are gravitating toward adopting this methodology. According to the Puppetlabs State of DevOps report, companies embracing DevOps principles can deploy their code up to 30 times more frequently than their industry counterparts. With a degree, certification, and experience, seek DevOps engineer positions. Compile a strong portfolio highlighting technical skills, certifications, and degrees.
