 For any resource that cannot be satisfied by the underlying platform, the platform MUST return an error and cease deployment. A resource is considered a requirement, and failure to meet that requirement means the runtime MUST NOT deploy the application. For example, if an application requests `1P` of memory, and that amount of memory is not available, the application deployment must fail. Likewise, if an application requires `1` gpu, and the runtime does not provide gpus, the application deployment MUST fail.
 
+If resources are not specified, the underlying platform is free to choose a suitable default.
