What is NOT a focus area of DevOps?

The focus areas of DevOps primarily revolve around practices and processes that improve collaboration between software development and IT operations. Typical areas include engineering, where the emphasis is on writing effective code and deploying it efficiently; operations, which involves maintaining the infrastructure and ensuring system reliability; and quality assurance (QA), which ensures that the software is not only functional but also high quality and meets user expectations.

Marketing is not a primary focus of DevOps because its main tenets are centered on the technical and operational aspects of software development and deployment. While marketing may play a supportive role in how products are positioned and communicated, it does not directly impact the core DevOps practices designed to enhance development speed, collaboration, and system stability. This delineation clarifies why marketing is the correct answer, as it does not fit within the traditional realms that DevOps seeks to integrate and streamline.
