What is devOps engineer | responsibilities, principles, tools, lifecycle, and more
Are you looking for ways to optimize your software development process? Consider implementing DevOps practices. It is one of the most advanced and efficient approaches to software creation with ultimate security and flexibility in mind.

In this article, we answer the question “What is DevOps engineer?” We also describe the responsibilities this specialist has, what the DevOps principles and tools are, and what is the best way to build a DevOps team for your project.

The Essence of DevOps: Why This Process Is Essential for Agile Development

DevOps stands for the combination of development and operations in the process of software creation. From a technical point of view, this is a practice that allows developers and operational specialists to work together more effectively, to create a high-quality product, and reduced the time it takes to bring it to market.

A lot of experts refer to DevOps as a software development culture that is highly focused on creating a top-notch, quality product that meets the customer’s expectations.

DevOps engineering is a beneficial approach for business. Implementing DevOps practices allows one to create software pieces with fewer errors, carefully test each part created and integrate it into the existing business processes, thereby reducing cost and speeding up the final product launch.

The main DevOps principles of continuous delivery, continuous deployment and continuous development also match perfectly with the Agile development methodology, which stands for high-end quality, flexibility in the development process, and a focus on customer needs.

What Is a DevOps Engineer

So, what is DevOps engineer? This person is an IT professional with great organizational and managerial skills, a deep understanding of a product development lifecycle and the customer’s business processes, who is responsible for ensuring effective collaboration between software developers, testers, and DevOps team members.

DevOps engineer is a person responsible for application development management, continuous integration (CI), and continuous delivery (CD) by setting up the different environments for different purposes, automatization of recurring tasks, monitoring system performance, and security protection against any cyber threats.

To get an answer to the question “What is DevOps engineer?”, take a look at the main responsibilities of this specialist.

DevOps Responsibilities: What Does a DevOps Engineer Do?

DevOps engineer roles and responsibilities cover the following tasks:

  • Delivery management. The process of delivery management and the DevOps lifecycle has a lot of points of intersection since both of these processes take place at each of the product development stages. DevOps engineer makes sure that tech team members are clear on goals, tasks, and deadlines.
  • IT infrastructure design and improvement. DevOps specialists are always reviewing the IT infrastructure design and improvements with the aim of creating more effective collaboration and reducing risks.
  • Performance testing. Since continuous delivery is one of the DevOps pillars, there is a need to test each piece of software created before its integration into the existing business processes.
  • Automation. A lot of DevOps engineer responsibilities imply repeated tasks with each of the software pieces. What do DevOps engineers do in this case? They automate them with the help of DevOps automation tools or create custom automation scripts.
  • Release cycles optimization. The continuous delivery approach requires DevOps engineers to constantly search for ways to optimize and improve release cycles, eliminate time drains and deliver better products faster.
  • Monitoring and reporting. Since continuous feedback is one of the DevOps principles, this specialist needs to control the process, report on the mistakes, and find ways to avoid them in a new cycle.
  • Security control. Most DevOps processes take place in the cloud, so there is a need for security control, which is one more task of a DevOps consultant. Despite being the last job on the list, it is one of the most important responsibilities of a DevOps.

DevOps vs Software Engineer

How do the roles of these specialists correlate with the tasks of a software programmer?ADevOps specialist’s responsibilities go beyond the responsibilities of a software engineer. That’s why it is impossible to start an IT career as a DevOp, and that’s why a DevOps engineer salary is higher than that of a software programmer.

While the core task of the software engineer is to create bug-free and well-performing code, the task of DevOps specialists includes partial project management. If we compare DevOps vs software engineer, DevOps developers ensure effective collaboration of programmers and DevOps team members, make sure that each piece of software works as it was planned, and aligns the product development process with the business needs of a customer.

DevOps Principles

DevOps principles are an integral part of the question “what is DevOps engineer?” Below are the most important principles followed at each step of the project development.

  • Collaboration. The idea of combining the development and operational parts of a project arises because of the lack of shared understanding and collaborative opportunities between operational and development teams. Previously, each team was engaged in its specific task, and their vision was limited by their scope of responsibility. DevOps allow teams to join their efforts, unite their vision and align each step of the development process with the current business needs.
  • Shared responsibility. Collaboration always means shared responsibility as well. As part of a DevOps culture, each of the teams is equally responsible for the quality of the final product.
  • Automation. Since most of the DevOps tasks repeat in each cycle, automation is the next principle that also allows for continuous integration and continuous delivery(CI/CD).

DevOps Lifecycle

The DevOps cycle goes in a circle at each stage of software development. These are the areas that need to be continually worked on:

  1. Continuous Development. The process of software creation is ongoing and each of its stages is carefully tailored to the business needs of the customer.
  2. Continuous Integration. The pieces of software created are integrated continuously into the business processes to meet the needs of the project and client. Together these DevOps lifecycle elements create a CI/CD approach.
  3. Continuous Testing. Each piece of code should be carefully tested during the early stages of the development process.
  4. Continuous Feedback. The DevOps and development teams are encouraged to share their feedback and constantly look for ways to eliminate errors and optimize the next software development cycle.
  5. Continuous Monitoring. DevOps engineers monitor how the created and integrated software performs and they look for opportunities to improve the performance.
  6. Continuous Deployment. This process is ensured by the containerization tools that allow for moving each of the software parts into production faster.
  7. Continuous Operations. Continuous operations are the shortest cycle ensured by DevOps operations automation tools.

Below are the most popular DevOps tools that are used by these specialists in the DevOps lifecycle.

  • Golang and Python. The tasks of DevOp engineers rarely involve creating code from scratch. This is the responsibility of a software programmer. However, sometimes they still need to create plugins and scripts to automate some of the DevOps processes and they use Golang and Python for this purpose.
  • Docker and Vagrant. These are containerization tools that allow one to separate software pieces and work with them independently of each other.
  • Amazon AWS. Amazon AWS is a cloud solution, and it is often used in DevOps processes. Cloud infrastructure allows the opportunity for each team member to work on the solution from any location and at any time, plus it provides the ultimate security for the code created.
  • Jenkins and Bamboo. These are the most popular CI/CD tools which are used during certain lifecycle stages.
