Description: An input parameter in the context of cloud formation templates is a variable passed to a template during its execution. These parameters allow users to customize the configuration of the resources to be created or modified, facilitating the reuse of templates for different environments or scenarios. When defining a parameter, its type, a default value, and a description can be specified, which helps guide the user in entering data. Parameters are especially useful in situations where flexibility is required, such as creating stacks for different regions, network configurations, or instance sizes. Additionally, parameters can be used to integrate values from other resources within the same template, allowing for greater interconnection and automation in infrastructure as code. In summary, input parameters are a key tool in cloud formation that enables developers and system administrators to define and manage their resources more efficiently and adaptively.
