A Lambda Alias is like a pointer to a specific function version. Users can access the function version using the alias Alias Amazon Resource Name (ARN). We can create one or more aliases Aliases against the same Lambda function. The upsert operation will first check the given Alias, if Alias is already present then update the Alias to refer given function version and if Alias is not present then it will create a new Alias. The operation will take the Alias name, description, additional argument, and function version as input and the function name from the Project property. Apart from the complete response, the operation will set the value of the previous function version, current function version, and Additional version weight details as plugin output. In case Alias is newly created then the value of the previous function version will be set as “NA”, If the Additional version weight option is not used in the Alias, “NA” will be set as plugin output. Operation will use the configured AWS cloud account to perform the operation.
