FAQ and troubleshooting

When you use ApsaraDB for RDS, you may encounter issues such as high CPU utilization and instance locking. For more information, see Q&A and FAQ & Troubleshooting.


Before you create an ApsaraDB for RDS instance, we recommend that you understand the following terms:

  • Instance: a virtualized database server on which you can create and manage multiple databases.
  • Region: a physical data center where the physical servers that host instances reside. In most cases, we recommend that you create RDS and ECS instances in the same region to ensure fast and stable access.
  • Zone: a physical location that uses independent power supplies and networks in a region. There are no substantial differences between zones in the same region.
  • Database engine: ApsaraDB for RDS supports the following database engines: MySQL, SQL Server, PostgreSQL, PPAS (highly compatible with Oracle), and MariaDB. For more information, see Database engines.
  • Network type: You can create an RDS instance in the classic network or a virtual private cloud (VPC). VPC is an isolated network environment on Alibaba Cloud. It is more secure than the classic network. We recommend that you select the VPC network type.
  • Edition: ApsaraDB for RDS provides the Basic Edition, High-availability Edition, and Cluster Edition. For more information, see ApsaraDB for RDS edition overview.
  • Instance family: ApsaraDB for RDS provides the shared, general-purpose, and dedicated instance families. For more information, see Instance families.
