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 that work 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.
OS permissions In addition to the permissions to develop your own management systems, you are also granted permissions on the database hosts. You are granted the permissions to develop your own management systems.
Database management permissions You have all permissions on the databases. You have most permissions on databases. However, you do not have the super user or super admin permissions 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 resources based on business requirements and configure resource overcommitment ratios for instances. These operations are performed within the dedicated cluster and do not affect other clusters. In most cases, all resources in a dedicated cluster are isolated from the resources of other clusters.
High database security
  • You can secure your data by using access link encryption, disk data encryption based on Bring Your Own Key (BYOK). You can also perform data and operation audits.
  • You can deploy enterprise-specific audit tools for data security.

  • You can deploy additional O&M tools, such as a custom monitoring component that is sophisticated.
  • Database administrators can have database management permissions and controllable OS permissions.
  • Intelligent diagnostics are provided to evaluate database performance and offer optimization suggestions.
  • Comprehensive O&M solutions are 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 instances based on existing specifications.
  • You can adjust the ratio for resource allocation in a dedicated cluster. You can also select an instance family that meets your business needs.
  • You can configure database specifications based on business needs. For example, you can configure high specifications for primary instances and low specifications for secondary instances. You can configure the specifications of each shard in a distributed database.
  • Fixed instance families are used. All instance types within an instance family have the same reuse rate for resources.
  • Fixed logic is used to configure database specifications.
