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.

 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.

  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...
