Using MongoDB Management Service (MMS) to build new development, test, and staging environments is a simple and efficient process that allows for unlimited restores and deployment of new environments from live production data. MMS provides a free tier for getting started with backup and restoration, while the newly released API enables programmatically controlled restores to automate environment setup. The goal of this process is to simulate production data without affecting the live environment, ensuring users have access to the most current data at all times.
