Comparison between ApsaraDB for MyBase and ApsaraDB RDS

Database feature ApsaraDB for MyBase RDS
Intended customers Large and medium-sized enterprises. Enterprise users and individual users in development and test environments.
Resource overcommitment The maximum CPU overcommitment ratio is 300%. If you use local disks, the CPU overcommitment ratio can be up to 200%. Resource overcommitment is not supported.
Resource scheduling Automatic resource scheduling is supported. No scheduling policies are used.
Operating system (OS) permissions In addition to the permissions to develop your own management systems, you are also granted other host permissions. You are granted the permissions to develop your own management systems.
Database management permissions You have all permissions on databases to fully integrate with existing application software. You have most permissions on databases. However, you do not have the super or sa permission on databases.
Resource isolation The CPU, memory, disk, and network resources in a dedicated cluster are isolated from the resources of other clusters. Database administrators can allocate the resources based on business requirements and set resource overcommitment ratios for instances. These operations are performed within the dedicated cluster and do not affect other clusters. In most cases, complete resource isolation is supported.
High database security
  • Access link encryption, disk data encryption based on Bring Your Own Key (BYOK), data audit, and operation audit.
  • You can deploy enterprise-specific audit tools for data security.
Access link encryption, disk data encryption based on BYOK, data audit, and operation audit.
Improved operations and maintenance (O&M) capabilities
  • ApsaraDB for MyBase has all O&M capabilities of ApsaraDB RDS.
  • You can deploy additional O&M tools, for example, a reliable custom monitoring component.
  • Database administrators can grant database management permissions and controllable OS permissions.
  • Intelligent diagnostics is provided to evaluate database performance and offer optimization suggestions.
  • A complete portfolio of O&M solutions is provided to implement backup and restoration, monitoring and alerting, and other features. For example, you can restore individual databases and enable per-second monitoring.
  • Industry-leading database solutions are provided, such as read/write splitting and the active-active architecture.
Elasticity
  • You can create the same instances based on existing specifications.
  • You can adjust the resource allocation ratio in a dedicated cluster. You can also define an instance family that meets your business needs and adjust it as needed.
  • You can specify flexible database specifications based on business needs, such as high specifications for primary instances and low specifications for secondary instances. You can specify the specifications of each shard in a distributed database.
  • Fixed instance families are used. Instance types within an instance family have the same resource reuse rate.
  • Fixed logic is used for setting database specifications.
