An ApsaraDB MyBase for SQL Server instance allows you to have more permissions than those you can have on an ApsaraDB RDS for SQL Server instance. This topic provides an overview of ApsaraDB MyBase for SQL Server and introduces related concepts.
ApsaraDB MyBase for SQL Server
- You can create one or more hosts in an ApsaraDB MyBase for SQL Server dedicated cluster. Then, you can deploy instances to these hosts. This way, you can isolate resources among hosts.
- You can use a compact or balanced resource allocation policy and configure the availability status of a host. For more information, see Enable or disable instance allocation on a host.
- You can configure resource overcommitment ratios to maximize resource usage and reduce costs.
- You can temporarily scale up resources for an instance for short-term use. This helps you handle business traffic surges. For more information, see Modify the configuration of an ApsaraDB MyBase for SQL Server instance.
