Final answer:
A statement like "I need to move the infrastructure to the cloud" is a user story and belongs to the product backlog in agile software development and project management methodologies.
Step-by-step explanation:
"I need to move the infrastructure to the cloud" is an example of a user story, which is a type of product backlog item often used in agile software development and project management methodologies like Scrum. A user story is a high-level definition of a requirement that contains enough information so that the developers can produce a reasonable estimate of the effort to implement it. This specific user story is focused on the task of transitioning from an on-premises infrastructure to a cloud-based solution, which would typically involve activities such as selecting a cloud service provider, planning the migration, ensuring security standards, and perhaps training the team on new tools and services.
