CI/CD is defined as a set of development practices that enable the rapid and reliable delivery of code changes. DevOps is defined as a collection of ideas, practices, processes, and technologies that allow development and operations teams to work together to streamline product development. While the two concepts are related, they are different in many ways. source: cicd vs devops | spiceworks
