Description: An object reference in a CloudFormation template is a mechanism that allows Amazon Web Services (AWS) users to refer to other resources within the same template. This is fundamental for infrastructure as code, as it enables the reuse and interconnection of resources efficiently. References are used to link different components, such as compute instances, networking components, and databases, facilitating the management and organization of infrastructure. By using references, users can create more dynamic and flexible configurations, where changes in one resource are automatically reflected in others that depend on it. This not only improves the maintainability of templates but also reduces the likelihood of errors by avoiding information duplication. In summary, object references are a key feature in CloudFormation that allows developers and solution architects to build and manage complex infrastructures more effectively and consistently.
