ApsaraDB for MongoDB provides the following service advantages over user-created databases:

ApsaraDB for MongoDB ECS user-created database Traditional user-created database
Availability Each instance has a three-node copy set. Disaster recovery switch is provided and migration is automated in the case of faults without impact on services and applications. Manual installation is required, and a multi-node copy set is deployed. Manual installation is required, and a multi-node copy set is deployed.
Reliability Highly reliable data assurance; automatic backup and one-click data recovery. Manual installation is required, and a multi-node copy set is deployed. Manual backup and data recovery. Manual installation is required, and a multi-node copy set is deployed. Manual backup and data recovery.
Scalability Elastic resizing, on-demand upgrade, high resource utilization rate, and upgrade process transparent to users and without service impact. Manual construction of a scalable architecture and self-assurance of the service impact caused by upgrade. A relatively long period of resizing deployment. Low resource utilization rate with considerations for peak. Manual construction of a scalable architecture.
Low cost Routine maintenance functions such as resource monitoring and database backup recovery. No O&M investment in machine installation and database deployment. Database maintenance by full-time DBAs. Database maintenance by full-time DBAs. Basic O&M by full-time O&M engineers.
