What is DevOps Engineering? Who is DevOps Engineer?

-

In today's world where information systems and technologies are changing and developing at a dizzying pace, roles, responsibilities and professions are also changing and transforming. One of the new roles that is frequently sought after and that we are used to hearing about is the DevOps Engineer. 

DevOps is an approach model that ensures that developed applications and systems are delivered to customers quickly and without interruption. The units and specialties that play a role in traditional product development, commissioning, maintenance and monitoring processes have left certain authorities and responsibilities to the DevOps Engineer with the establishment of the DevOps approach and culture. 

This new organizational structure seems to have created a position that is key and can manage several departments and software systems like an orchestra conductor and at the same time overcome problems with technical knowledge.

What should a DevOps Engineer know?

  • First of all, he/she must have good communication and coordination skills.
  • He/she must be familiar with Software Development Life Cycle (SDLC) processes.
  • He/she must know the basics, working logic and solutions to frequently encountered software or system errors of a widely used programming language (C#, Java, Python etc.).
  • He/she must be familiar with the installation and configuration of the application server (IIS, Tomcat, Apache) where the applications developed according to the programming language used are published.
  • He/she must be able to manage the developed applications in the Container (Docker, Kubernetes) environment.
  • He/she must have knowledge of at least hardware, virtualization and file system issues for Windows Server and Linux operating systems.
  • He/she must have knowledge and experience in cloud platforms (Azure, AWS, Google Cloud etc.).
  • Basic Linux commands must be known, especially network commands.
  • He/she must be familiar with basic network and security concepts and concepts.
  • He/she must know how to use CI / CD tools and create pipelines.
  • Must have knowledge about Infrastructure and Software Monitoring software and be able to use at least one of these tools.

What are the Roles and Responsibilities of a DevOps Engineer?

  • To be in communication with Software Development and System engineers. To ensure coordination between teams when necessary.
  • To take part in automating processes and managing the infrastructure.
  • Creates and tests the distribution and delivery process of the developed application using CI / CD tools.
  • Continuously monitors and analyzes system performance and security.
  • Proactively detects, examines and fixes critical errors and problems in applications.

In summary, the main task of a DevOps engineer is to ensure efficient collaboration between technical teams, manage code integration and deployment, monitor system performance and security, and contribute to the continuous improvement of processes. Thus, faster, uninterrupted, secure and high-quality software deliveries and process optimizations can be achieved.

  DevOps is a methodology that aims to increase communication and collaboration between software development teams, security teams and IT operations teams. Continuous Integration (CI)   : The practice of control mechanism that automate and test all code changes in a code branch. This control provides possible bugs and problems early and fix them immediately. This control cycle provides quality assurance so software quality increases.  Continuous Delivery (CD) : If code has no error and built successfully, it is sent to production environment automatically by creating CD pipeline. This is called continuous delivery. In this concept, we always "use" delivery instead of "deployment" term ☺Continuous delivery provides us transfer any changes of code to test, pre-prod or production environment. We can also automate and monitor this delivery process detailly.  Source Code Version Control Tools : These tools is very useful and important for managing and versioning code ch...

Continuous Integration and Continuous Delivery (CI / CD) Pipeline

 In previous post, I mentioned a bit about CI/CD. Now, I will try to explain detailly about CI/CD pipeline that is main skeleton of DevOps approach. Developers and IT operation teams work together to deliver the software during CI/CD pipeline steps.  The main benefit of CI/Cd pipeline, automation of software releases. Other benefits are reduced deployment time, decreased operaiton costs, continuous feedback ann monitoring so early error detection,  enhanced reliablity and reduced downtime, increased collaboration between teams. Let's detail of CI / CD pipeline steps a bit more;  Plan:  When we are in a process of developing a software in a company, probably this is a part of a project or IT service (change or incident).  Let's suppose Agile project management. (for getting deep information about agile approach, please visit Scrum Website ) For project, Scrum Master sets sprint plan. At the end of the sprint, DevOps teams must deliver a "value" (like a worki...

Dev : Software Development Sec : Information Security Ops : IT Operations. DevSecOps is the collaboration of Software Development, Information Security and IT Operations that includes a set of applications, tools and mindsets.  Main objectives and principles of DevSecOps; Continuous Integration & Continuous Delivery (CI/CD) Automation Logging  Monitoring Collaboration & Comminucation Mindset & Cultural Adaptation DevOps approach covers all part of the software development lifecycle (SDLC) and is involved in all processes from planning to development, testing, deployment, and monitoring of a software. This approach allows software to be developed and delivered faster, more reliably, and more efficiently.
