What does a DevOps engineer do?
The central point in process improvement
DevOps is an approach to Process improvement in software development and system administration. The designation is made up of the terms Development (Development) and IT operations (IT operations) together. The DevOps model is about bringing together these previously isolated company areas.
What is DevOps?
In a DevOps structure there is a cooperation of the two areas with the aim of equally the productivity in the development as well as the reliability of the operational processes optimize.
Common Incentives, coordinated processes and software tools are intended to improve cooperation between the departments and the quality assurance enable. It should also be able to react more quickly to changes in development processes.
The basis of the DevOps concept is therefore one Culture of collaboration between teams that have tended to work separately up to now. A DevOps Engineer is accordingly one mixture from a software developer (developer) and a system engineer (administrator).
What does a DevOps Engineer do
Since the activities represent a mixture of different areas of responsibility, the The tasks of a DevOps engineer are very varied. This includes the design and creation of scripts and Development tools for agile software development, the execution of Administrative activities, the Monitoring, the Conception and implementation of Software testing as well as finding and optimizing solutions for operational processes.
A central one DevOps method is the establishment of frequent, small updates. According to agile procedural methods, companies can thereby participate their customers more closely in the development process and allow the product to mature in a more targeted manner. Frequent, small updates mean that there is less risk of wrong paths being detected late. Errors are easier to find from update to update and can be dealt with in smaller units.
Another important DevOps practice is that use a microservice architecture. This breaks up large, complex, monolithic systems into smaller, simpler, independent systems. Every function of an application is called a component (Service) implemented independently of the other components and the overall application. A small, agile team is fully responsible for every service. At Updates this reduces the Coordination effort.
In the DevOps model, responsibility goes beyond the conventional responsibility model, which only affects a sub-area of the end product for the entities involved. Teams that work according to the DevOps model feel responsible for the entire development and life cycle of the product.
The combination of microservice architecture and high update frequency makes corporate applications more flexible and enables them faster innovation cycles.
The increased frequency of deployments creates new operational challenges. DevOps practices such as continuous integration and continuous delivery are designed to enable reliable deployments under these conditions. Everyone pulls Code change a row automated tests after yourself. Builds that pass these tests will be over as well automated deployments provided.
DevOps engineers can also use Monitoring and logging methods Track application and infrastructure performance and respond quickly to problems.
What skills does a DevOps engineer need?
Indispensable for DevOps Engineers is one Passion for programming and scripting. Typical programming languages that DevOps engineers deal with are Python, Java, Ruby and PHP. For the administrative side, knowledge comes in various Server systems for Windows, Mac or Linux, especially Security concepts are important. Dealing with Open source technologies and tools is a central part of the work.
Other important competencies are in addition to technical and professional knowledge independent work and the soft skills.

Various courses of study and training provide the basis for the DevOps professionComputer science, business informatics, information technology or specialist informatics. Come as an apprenticeship IT or related qualified degrees into consideration, like that of the IT system administrator. It is important to acquire software development and administrative knowledge at the same time. Dual courses of study provide a broader basis for this.
There are some today Certification opportunities for the profession of DevOps engineer, e.g. AWS Certified DevOps Engineer or LPI Certified Open Technology DevOps Engineer.
Where can I work as a DevOps Engineer? What salary can I expect?
The position of DevOps is increasingly finding its way into numerous industries with a high IT relevance. More and more companies are relying on the DevOps culture for their IT departments in order to bring together previously divided roles. Young professionals are often in demand, i.e. young professionals with a bachelor's or master's degree who have already gained one to two years of practical experience in development and administrative areas.
The average annual starting salary of a DevOps engineer is around EUR 49,000 to EUR 54,000. The job description of a DevOps engineer differs from company to company, so the salaries can be great differently be. As usual, there are also fluctuations depending on the responsibilities and competencies assigned.
