What are Tags used for in OCI?

Tags in Oracle Cloud Infrastructure (OCI) are primarily used for the categorization and management of resources. They enable users to organize and identify resources more effectively by applying key-value pairs. This categorization can be crucial for both management purposes and billing, allowing users to track and allocate costs to specific projects, departments, or applications.

By using tags, users can quickly filter and search for resources based on these defined categories, providing better visibility and control over the cloud environment. For instance, if an organization needs to manage multiple development environments, they can tag resources according to environment type (development, testing, production) which simplifies monitoring and reporting.

While other options might touch on functionalities related to resource management or operations, they do not accurately capture the core purpose of tags. For instance, server load management and resource scaling are typically handled by different service features within OCI, while security involves other mechanisms and best practices outside of tagging. Thus, tagging serves as a valuable organizational tool specifically designed for resource management.
