FAQ and troubleshooting

When you are using ApsaraDB for RDS, you may encounter issues such as high CPU usage 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 concepts:

  • Instance: a virtual database server, on which you can create and manage more than one database.
  • Region: a physical data center, where the physical servers that host instances reside. In normal cases, we recommend that you create your RDS and ECS instances in the same region to ensure fast and stable access.
  • Zone: a physical location, which is provided with independent power supplies and networks in a region. Zones in the same region provide the same services.
  • Database engine: ApsaraDB for RDS supports the MySQL, SQL Server, PostgreSQL, PPAS (highly compatible with Oracle), and MariaDB database engines. For more information, see Quick Start.
  • Network type: You can create your RDS instance in a classic or Virtual Private Cloud (VPC) network. VPC is an isolated network environment that is built on Alibaba Cloud. It is more secure than a classic network. We recommend that you select the VPC network type to meet your business requirements.
  • Edition: ApsaraDB for RDS provides three editions. These editions are Basic Edition, High-availability Edition, and Cluster Edition. For more information, see ApsaraDB for RDS edition overview.
  • Instance family: ApsaraDB for RDS provides three instance families. These families are general-purpose instance family, dedicated instance family, and dedicated host instance family. For more information, see Instance families.
