DevOps is a software engineering practice that deals with the operationalization of software. Common elements of DevOps are version-controlled code, continuous integration and continuous delivery (CI/CD) pipelines, unit testing, and reproducible code builds and deployment, which all involve code. ML models are a product of code and data, so data has to meet the same standards as code. MLOps must address data-related questions such as how to maintain data quality, how to identify edge cases in data, how to secure data, and how to make data more maintainable.
