Continual deployment impacts software quality by allowing for frequent updates and iterations, enabling teams to respond quickly to user feedback and fix bugs more rapidly. This practice emphasizes a DevOps culture, integrating development and operations to streamline the software release process. With continual deployment, automated testing ensures high-quality code is delivered consistently, minimizing the chances of disruptions. However, it also requires robust monitoring and rollback mechanisms to address any unintended consequences quickly. Ultimately, this approach fosters a culture of rapid innovation while maintaining a focus on delivering reliable, high-quality software products to users.
