DevOps Engineer

The software development process is lengthy and contains several processes. DevOps is a methodology for shortening the time it takes to complete the software development cycle. “Automation” is the keyword in DevOps. DevOps approaches combine well with agile and continuous delivery methodologies, allowing software to be provided quickly. DevOps ensures that system delivery, innovation, and knowledge are all improved over time. As a result, these methods can help software engineers learn faster.

DevOps Engineer Certification is available for students online and offline to build their careers in this domain. 

Who is a DevOps Engineer?

An IT professional with a thorough grasp of the software development lifecycle is known as a DevOps engineer. They must comprehend why the company was forced to switch from one model to another, as well as the drawbacks of the prior model and the advantages of the new model.

A DevOps engineer must also be familiar with a variety of automation technologies for constructing CI/CD pipelines. This high-demand profession necessitates a unique combination of DevOps abilities, which we’ll go over in further detail later.

In a CI/CD pipeline, there are several steps. The planning stage, which includes designing an algorithm for your product, is the first step. The algorithm is then converted into a usable product in the following level, which is the constructing stage.

The product is subsequently put through its paces in the testing stage, where all defects are discovered and fixed. Finally, the product reaches the deployment stage, where it is introduced to end consumers. After the product has been delivered, it must be continually monitored, which is a new notion in the DevOps lifecycle.

In comparison to the preceding stages, DevOps engineers place a greater emphasis on the monitoring step. It’s critical to keep an eye on the product at all times to catch new issues, patch them, and send the updated version back to the customer. This is done to guarantee that once the product is out into the actual world, customers are satisfied. DevOps engineers work with development and operations teams to provide high-quality products in the shortest amount of time feasible.

Roles & Responsibilities 

DevOps engineers, like software engineers, can write code for an application, but they also handle build, deployment, and operations as part of a continuous automated process once the code is written. They collaborate with business people to manage the whole workflow and ensure that the software is functional by connecting it with automated operations.

A large portion of the daily job is around building and deployment, as well as reporting results to the appropriate teams, automation, and configuration. However, if necessary, programming is required to bridge the gap between the development and operations teams.

To construct and deploy software systems, a DevOps engineer collaborates with both the development and operations teams. As a result, they’ll need to work with software developers, quality assurance specialists, and other IT personnel. The following are the primary duties and responsibilities of a DevOps engineer:

  • Create documentation for the functionalities on the server side.
  • IT solutions are developed, installed, tested, configured, and maintained.
  • Everyone on the team should be aware of operational requirements and development predictions.
  • Develop strategies and procedures for improving and expanding the present technology.
  • Using configuration management software, deploy updates to the production environment automatically.
  • To guarantee that the production environment operates well, perform frequent application maintenance and troubleshooting measures.
  • Conduct a gap analysis to find performance improvements, alternative solutions, and help with changes.


Programming skills

For DevOps engineer roles, competition and peer pressure are always strong, and if you want to stay ahead, you’ll have to go above and beyond. Learning a few coding languages such as Python, Java, Ruby, or anything similar can place you in a better position than merely being the network or IT guy.

Are you aware of what a system administrator is aware of?

A system administrator is responsible for a large number of tasks. Daily, he is in charge of building, deploying, testing, debugging, and repairing servers. He monitors the system’s health regularly and works on significant concerns. DevOps workers should also focus on automating the most critical aspects of the server and infrastructure deployment process. One of the most critical abilities of a DevOps engineer is the ability to communicate effectively.

Storage and network

DevOps experts should be able to manage network difficulties since they deal with a lot of servers, connections, data, and storage. This implies that they should be familiar with IT network and storage fundamentals. 

Compliance and infrastructure management

The DevOps workflow may be applied to new systems. Legacy systems, on the other hand, must be addressed and brought into the DevOps world. These systems should be secure, scalable, balanced, with enough backups, and compliant. All of this should take place without disrupting any current businesses. In other words, actions that were previously completed manually must now be automated. Some functionality may be harmed or broken as a result of the procedure. As a result, a DevOps engineer must be familiar with cluster management tools and containerization to guarantee that old systems and future deployments are seamlessly integrated.

Tools for automation

Puppet, Kubernetes, and Jenkins are the most popular DevOps tools among the numerous available DevOps automation technologies. The ultimate objective of the DevOps approach is automation. Every task must be automated, from code generation to building, testing, and deployment. Monitoring and post-production testing were also automated, allowing for faster results and continuous integration. Continuous Integration, Continuous Testing, and Continuous Deployment, which is a recurrent process, make up the DevOps pipeline.

Additionally, infrastructure setup, software deployment, and settings may all be automated, resulting in increased speed, reliability, consistency, and, most significantly, a higher number of precise deliveries. Knowing how to use any of the automation technologies can help you advance in your DevOps profession.

Cloud computing and virtualization

Running a virtual instance of a computer system in a distinct layer insulated from the actual hardware is referred to as virtualization. Virtualization divides a huge system into smaller ones, allowing the server to serve a larger number of users or applications with varying requirements. It also isolates any software running on one machine from the others.

As a result, virtualization is critical for DevOps. Consider how the development team and the operations (IT) team might collaborate and be in sync if we could virtualize the hardware and construct a duplicate of the current network. This will also allow for a more smooth testing experience.


If you’re familiar with agile approaches, you’ll know that the development process is gradual and iterative. Testing and development are inextricably linked. DevOps is the next logical step. Testers don’t only test functionality; they test all aspects of the system, including operations, performance, security, and data and log analysis. From planning to branching, coding, merging, building, releasing, deployment, operations, and monitoring, testing occurs at every level. A DevOps engineer can use a variety of tools to do continuous testing and integration.

Effective communication abilities

Last but not least, a DevOps engineer must be able to communicate effectively. Because he serves as a liaison between the IT and development teams, he must be able to effectively coordinate both. Furthermore, you will always be a part of a large team as a DevOps engineer, which means there will be a lot of contact and conversations. The key to good communication is communicating the appropriate points at the right moment. This talent can help you obtain any job, not only DevOps engineer jobs.


Isn’t the list long and winding? As previously said, you might be an expert in one field yet be clueless in another. It’s all right. Each of these talents should be learned at a basic level, to begin with. If you work as a software engineer, for example, you are undoubtedly skilled in programming. Because you may have done some of the tasks in a development environment, doing the work of an administrator should not be difficult for you.
