Integration of DevOps methodology into the software development process

Abstract

Software development became one of the core priorities of modern companies, due to increased demand for use of IT technologies in products and services offered. Having the website as well as a mobile application to represent offered services means gaining a competitive advantage against other players on the market. As the number of products available on the market increases so have the requirements for their quality and stability from the end-users. To keep up with such standards new methodologies for the software development process have arisen. The most widely used today are Agile and DevOps. For such reasons, this thesis is mostly dedicated to describing the process of creating the development and production environment that will embrace the methodologies of DevOps. The first chapter of this thesis is dedicated to defining the software development life cycle and its parts as well as the difference between the most popular software development methodologies that are used to create a product. Based on the described methodology of Agile application development combined together with the DevOps concept of combining two essential parts of the project - development, and operations, the system is presented in the second chapter. The project will be composed of three independent parts: Application, Infrastructure, and CI/CD tools. In the next chapter, the technological tools and solutions used in the thesis are described with an analysis of the alternatives available on the market as well as advantages and disadvantages in some of them. The last chapter is dedicated to the implementation of the system described above, the first part will include the implementation of the application that is being brought through the DevOps lifecycle. The second part describes the infrastructure setup and configuration of CI/CD tools as well as the process of creating the pipelines dedicated to application testing, building, and deployment to the infrastructure in the containerized form.
