Cloud Development Environments (CDEs) like Gitpod offer significant financial benefits that justify their adoption by addressing common development challenges and improving productivity. An ROI calculator has been developed to help companies quantify these benefits, focusing on reducing issues such as "works on my machine" problems, lengthy setup times, and dependency conflicts, which can save developer time and enhance productivity. CDEs also expedite developer onboarding by providing preconfigured environments, reducing onboarding times by 75%, which translates into substantial cost savings. For example, a company with 100 developers can save up to $1.8 million annually by reducing troubleshooting time, and another $144,000 by minimizing onboarding inefficiencies. Overall, implementing CDEs can enhance engineering capacity by 19% and provide a return on investment of 913% after accounting for associated costs. The calculator allows customization of parameters to tailor the business case to specific company needs, and further support is available for incorporating additional CDE features into the analysis.
