You enter the software development world and realize that the current trend is to opt for a DevOps methodology. The focus on high-quality services seems to be paramount for software development companies. But what does this mean, what is this methodology, and why is the DevOps engineer one of the most demanded?
First, you must know that DevOps is a work philosophy that allows an efficient flow of tasks and good coordination between all the areas performing software development. The result: a permanent delivery of excellent quality.
But are you still unclear about what a DevOps engineer is and what they do? Don’t worry; in this article, we will solve the mystery. In addition, we will give you some tips to increase your chances of being hired by a company with this approach.
What is DevOps?
Before knowing what a DevOps engineer does, defining what “DevOps” is all about is convenient. They are a set of practices focusing on software development and IT operations. Its main objective is to optimize the lifecycle of this process while performing a constant delivery of service of the highest quality.
In other words: DevOps pursues the unification and automation of processes while fostering the collaboration of work areas. In order to work with DevOps practices, it is necessary to have an engineer in the field.
What is a DevOps Engineer?
A DevOps engineer, also known as a DevOps Engineer, is an IT professional who performs tasks within the framework of the DevOps approach. Generally speaking, they perform permanent monitoring of the software development lifecycle. To do this, he must function as a link between the programming teams and the operations teams. In addition, it ensures that the software being developed can be executed smoothly on systems and servers.
The main objective of a DevOps engineer is to optimize the delivery of software solutions by integrating and coordinating the development and operations teams. In this way, by incorporating specific methodologies, they can provide speed and quality in the delivery.
By the way, if you have gaps in other educational areas while studying the profession of DevOps engineering, you can easily help with online educational support, which also saves time and money, for example, when using paperhelp discount codes.
What Are the Functions of a DevOps Engineer?
As we have said, DevOps engineers carry out the system development life cycle (SDLC). This is, simply put, the process of developing, analyzing, designing, implementing, testing, deploying, and maintaining an information system.
These professionals oversee all these phases from start to finish. At the same time, they ensure that collaboration between teams flows smoothly.
Among other tasks, a DevOps Engineer is responsible for the following:
IT infrastructure improvement: these engineers know the projects throughout their entire cycle and perform constant analysis to improve them.
Process automation: with tools such as Jenkins, Puppet, or Ansible, DevOps engineers use automation to reduce time in repetitive tasks such as building, testing, and deploying software. In addition, this allows them to reduce human error and improve overall quality.
Systems implementation: these IT experts are responsible for implementing and configuring systems, servers, and platforms in Cloud Computing.
Version management: they also manage software versions and handle changes to the source code. They may use Subversion, Mercurial, or Git tools to do this.
Cross-team coordination: DevOps engineers are usually in charge of managing communications and receiving information from different areas. Therefore, they have solid interpersonal tools that allow them to carry out their work best.
Security monitoring: All software needs constant monitoring to prevent it from being vulnerable to information theft. DevOps engineers also ensure data protection against internal and external threats.
Knowledge and Skills of a DevOps Engineer
We have already said what a DevOps engineer does. Now, knowing what skills one of these professionals must have remained. Generally speaking, the technical skills of a DevOps engineer are as follows:
- Programming. The DevOps engineer must know the programming languages used in software development and related technologies, such as integrated development environments (IDE).
- Data management. Creating software involves a large amount of data, so it is essential to know SQL and databases.
- Version control. Git, SVN, or Mercurial are essential to managing source code. DevOps engineers can rely on them to facilitate collaboration in development teams.
- Operating systems and virtual machines. You must have a solid knowledge of configuration, monitoring, and troubleshooting Windows and Linux environments in containers such as Docker, Kubernetes, or VMware.
- Cloud computing. Undoubtedly, knowing how to manage cloud platforms and their tools is necessary.
- Security. From authentication to authorization and encryption, you must have notions about security in software development and deployment processes.
- But technology is not everything. DevOps engineers must also possess a number of soft skills, that is, those related to applying emotional intelligence on the job:
- Communication skills. The DevOps engineer must coordinate teams, so it is essential to have assertive and effective communication.
- Learning ability. Must be willing to adapt to new technologies quickly.
- Problem-solving skills. Having diagnostic skills and working under pressure to resolve issues is important.
- Attention to detail. In a job where quality delivery is everything, attention to detail must be constant.
