Abstract: Technologies are disclosed for storage and retrieval of parameters used in the creation and editing of infrastructure-as-code (IAC) templates. An infrastructure-as-code (“IAC”) template related to desired resources available in a service provider network for configuring a stack of the desired resources in the service provider network is provided. The IAC template includes an identification of a key-value pair associated with resource definitions related to the desired resources and are stored in a data store. Based upon the identification of the key-value pair, a look-up function is used to call a stateless event driven compute service function to query the data store for the resource definitions. Once the resource definitions are received from the data store, based upon the IAC template and the resource definitions, the stack of the desired resources is configured.
