Self-hosted CI/CD solutions offer control and customization but require manual updates, security measures, and infrastructure management, which can be time-consuming and costly. In contrast, fully managed CI/CD platforms provide a low-maintenance option with built-in security features, scalability, integration power, and access anywhere, anytime. Fully managed solutions also tend to have lower costs and higher developer velocity, as they allow developers to focus on innovation rather than maintenance. Ultimately, the choice between self-hosted and fully managed CI/CD depends on an organization's specific needs and priorities.
