We have often heard of growing popularity recently: DevOps. In our country, you can access many blog articles, articles, and content on this subject. Although the essence of the subject is correctly explained in many of these articles, I think there are some shortcomings. In this article, while completing these points that I see missing from my point of view, I will also correct the false perception that DevOps is just a technical approach due to these missing points.
DevOps is a framework that has philosophical roots in which all stakeholders can work effectively with optimum efficiency to produce an IT product and maintain a healthy life.The word DevOps is an approach that results from the combination of the words Development and Operations. It was first mentioned at the Agile 2008 conference and then began to become widespread with the activities held in this field. DevOps is defined as a software development method that emphasizes automation, communication, collaboration, and integration.
DevOps says that software development, quality (QA), and IT Operations must be in solidarity with each other. Thus, it aims at an organization to quickly produce software and services and to increase its operational performance. As can be seen from here, DevOps is not only a technical approach but an organizational culture approach. In other words, we can say that the concept we know as the culture of collaboration (also called Agile culture) has taken its place in the market with a different name.
In order for DevOps culture to be adopted by an organization, some situations must occur in the corporate culture. We can list these situations as follows:
- Using Agile software development processes and methodologies
- Increasing requests to expand live environments from business units
- Virtualization and availability of cloud infrastructures
- Increased use of data center automation and configuration tools
- Focus on Test Automation and Continuous Integration approaches
When we look at these situations when DevOps is called, only Docker, Puppet, Chef, Jenkins, Bamboo etc. We should also consider that approaches such as Scrum / Kanban / XP, TDD, Continuous Integration, BDD are mentioned as well as the operational approaches of such tools. In fact, I would like to point out that it is important to prioritize organizational approaches to lay the foundations and strengthen DevOps.
Who is DevOps Engineer?
DevOps is a software development strategy that allows bridging the gap between software developers and IT staff. DevOps engineer is the person who understands the software development lifecycle and fully uses various automation tools to develop digital pipelines (CI / CD pipelines). DevOps engineer is an information technology (IT) specialist working with software developers, system operators (SysOps), and other production IT staff to oversee code developers. It works with developers and IT staff to control code releases.
What are the Duties of the DevOps Engineer?
DevOps engineers can act as either operational developers or system administrators moving to the coding area. Among the duties of DevOps engineers, who are also responsible for software development;
- To have a solid knowledge of computer programming languages and to recognize the basic concepts of Linux,
- Working with various open-source tools and technologies to manage the source codes,
- To have comprehensive knowledge about IT operations and sysadmin roles in order to regulate the entire integration and deployment process,
- Testing and distributing software codes,
- To develop automation tools to work flawlessly by developing software.
Who Can Become a DevOps Engineer?
To be a DevOps engineer who provides software development to facilitate the work of the IT department in institutions with a high number of servers, you must graduate from the university’s four-year computer engineering department. You can become a DevOps engineer by getting DevOps training from the authorities.
What Training is Required to Become a DevOps Engineer?
To be a DevOps engineer aiming to increase the efficiency of the business by working together with software developers and IT operation units; DevOps concept and basics, Powershell basics, Linux shell scripting, python scripting, infrastructure as code, continuous integration, configuration management, monitoring should be taken.
What Does DevOps Engineer Do?
DevOps engineer bridges the software and operation. When the developer writes his code, the software is compiled with a single click and becomes operational on the server. The tests on it run automatically. If there are problems with reviews or tests, they are reported immediately.
The software is transferred to the test rate at the desired periods and the tests are provided by the users. In the next step, it spreads to production systems.
If an error occurs in production due to the last warehouse, DevOps engineer can get it back instantly thanks to automation.
With system monitoring, system logs and resource usage are monitored. Errors in the logs are either resolved by on-site intervention or reported to the developers.
With the bug tracking system, errors from users are collected and reported to the software team.
DevOps engineer dominates the operation of the system. Finding the knowledge and skills of DevOps engineers and stakeholders in DevOps is a prerequisite for the operation of the system.
So, thanks to DevOps engineers, quality products come out over time. While providing trust and rapid cooperation between teams, the software is released faster and smoother. “Continuous Improvement” can be applied more frequently and easily.
The biggest change that comes with DevOps engineers is the team members who used to work separately and with different skills; system administrators, developers, database administrators, system analysts, etc. to come together and form a single team. This collaboration in different roles has many advantages. Technically, while improving the Continuous Delivery, the reduction of confusion is an advantage that cannot be overlooked. Faster solutions will start to be found for the problems. Engineers who implement the DevOps culture also have benefits for the business. These; faster delivery of product features, more stable systems, and more time than troubleshooting.
