Description: In the context of infrastructure as code, an ‘overridable’ value refers to the ability to modify or replace a default value in a template. This allows users to customize the configuration of their resources without the need to create multiple templates. Overridable values are particularly useful in environments where flexibility is required, such as in the development and deployment of cloud applications. By defining parameters in a template, users can specify values that can be adjusted at the time of stack creation or update, thus facilitating adaptation to different environments or specific requirements. This feature not only enhances template reuse but also simplifies infrastructure management, enabling development and operations teams to implement changes more quickly and efficiently.
