Self-hosted continuous integration (CI) tools, once the norm, have evolved to complement cloud-hosted solutions by offering unique benefits for specific use cases. While cloud-hosted CI provides flexibility and scalability, self-hosted CI infrastructure allows teams to maintain control over their computing environment, ensuring privacy and security, especially crucial in highly regulated industries like banking and healthcare. Self-hosted CI is advantageous for development scenarios requiring unique resource configurations or privileged access controls, such as testing on specific hardware or managing sensitive data securely. Teams can integrate self-hosted runners with cloud-based CI systems, such as CircleCI, to leverage the strengths of both environments. This hybrid approach allows for optimized resource management and cost savings, offering greater control over testing environments, which increases confidence in application performance and streamlines development processes. As the landscape of computing continues to grow and diversify, self-hosted CI remains a valuable option for addressing specific organizational needs.
