Which cloud feature lets a developer deploy a test environment quickly with minimal configuration?

Self-service and rapid elasticity are key cloud features that enable quick deployment of test environments with minimal configuration. Self-service allows developers to provision resources on demand without IT intervention, streamlining the process. Rapid elasticity means resources can be scaled up or down quickly and automatically based on needs, ensuring the environment is available when required and optimized for cost. Manual provisioning is slow and requires significant human effort, making it unsuitable for quick deployments. On-prem virtualization, while offering some flexibility, still involves managing physical infrastructure and is not as agile as cloud-based self-service. Platform as a Service (PaaS) is a cloud service model that provides a complete development and deployment environment, but "self-service and rapid elasticity" are the underlying cloud characteristics that enable PaaS to be effective for quick deployments, making it a more fundamental answer to the question.
