Chronicles of CI/CD: A Deep Dive into its Usage Over Time
<|reference_start|>Chronicles of CI/CD: A Deep Dive into its Usage Over Time: DevOps is a combination of methodologies and tools that improves the software development, build, deployment, and monitoring processes by shortening its lifecycle and improving software quality. Part of this process is CI/CD, which embodies mostly the first parts, right up to the deployment. Despite the many benefits of DevOps and CI/CD, it still presents many challenges promoted by the tremendous proliferation of different tools, languages, and syntaxes, which makes the field quite challenging to learn and keep up to date. Software repositories contain data regarding various software practices, tools, and uses. This data can help gather multiple insights that inform technical and academic decision-making. GitHub is currently the most popular software hosting platform and provides a search API that lets users query its repositories. Our goal with this paper is to gain insights into the technologies developers use for CI/CD by analyzing GitHub repositories. Using a list of the state-of-the-art CI/CD technologies, we use the GitHub search API to find repositories using each of these technologies. We also use the API to extract various insights regarding those repositories. We then organize and analyze the data collected. From our analysis, we provide an overview of the use of CI/CD technologies in our days, but also what happened in the last 12 years. We also show developers use several technologies simultaneously in the same project and that the change between technologies is quite common. From these insights, we find several research paths, from how to support the use of multiple technologies, both in terms of techniques, but also in terms of human-computer interaction, to aiding developers in evolving their CI/CD pipelines, again considering the various dimensions of the problem.<|reference_end|>
