The purpose of software for continuous integration and continuous deployment (CI/CD) is to automate the process of software development, enabling teams to frequently integrate changes and deliver updates swiftly and reliably. This reduces the time between writing code and deploying it, promoting faster feedback from users and streamlined collaboration among developers. By using CI/CD tools, organizations can improve their software quality, mitigate risks associated with manual deployments, and enhance productivity by allowing teams to focus on delivering features rather than maintaining infrastructure.
