A method, apparatus, and computer-readable medium are described that gather information from subnets of a virtual private cloud, compare the information of the subnets to criteria of components of a service, and identify selected subnets that comport with the criteria. The subnets may be associated with different availability zones. The selection of any subnet may affect the subnets available for the next selection. The process may dynamically adjust for previous subnet selections and may be available as a service. Based on a call to the service with criteria of the components, the service may request information regarding the subnets and return an identified list of subnets for the components. The process may accommodate services during development stages and during deployment stages and/or account for primary and secondary subnet assignments. By dynamically adjusting the available subnets, delays in subnet selection and subsequent deployment may be reduced.
