This topic describes ApsaraDB for MyBase (ApsaraDB for MyBase).
ApsaraDB for MyBase, ApsaraDB for MyBase for short, is a dedicated database solution. ApsaraDB for MyBase is developed by Alibaba Cloud to provide customized and optimized database services for enterprise users. An ApsaraDB for MyBase dedicated cluster consists of multiple underlying hosts. These hosts can be Elastic Compute Service (ECS) instances in the i2 instance family or ECS Bare Metal instances. An ApsaraDB for MyBase dedicated cluster provides more database services than fully managed database solutions.
ApsaraDB for MyBase supports multiple database engines, such as MySQL, SQL Server, and PostgreSQL. ApsaraDB for MyBase allows you to use dedicated cloud resources and supports resource overcommitment. ApsaraDB for MyBase also supports customized O&M and allows you to grant users permissions on specified databases in a dedicated cluster and specified permissions on the OS.
