Description: A template parameter is a variable used in the context of creating infrastructure-as-code templates, allowing users to define values that can be replaced at the time of deployment. These parameters are essential for customizing and reusing templates, as they enable developers and system administrators to specify configurations without needing to modify the template code itself. Parameters can include information such as resource names, network configurations, instance sizes, and other values that may vary across different environments or deployments. By using parameters, the flexibility and maintainability of templates are improved, facilitating cloud infrastructure management and deployment automation. Additionally, parameters can have constraints and validations, ensuring that the provided values meet certain criteria, thus increasing the robustness of the implementation.
