With RDS Custom, you can flexibly handle various scenarios, such as integrating cloud databases with platforms and deploying hybrid business applications.
Product introduction
RDS Custom is an open cloud database service that provides database kernels and containerized management services. RDS Custom lets you access the underlying operating system and database environment. It offers lightweight management features that are compatible with existing O&M platforms. This helps you flexibly integrate cloud databases with your platforms and deploy hybrid business applications.
The following figure compares RDS Custom instances with self-managed databases and regular RDS instances.
Product Features
Grant access privileges to the operating system on the host
Grants access to the operating system and database environments for independent O&M and management.
Provides OpenAPI operations for host management. These operations are compatible with ECS API operations and can be quickly integrated into your platforms.
Provides independent database host types to help you create a unified resource pool.
Integrated deployment of databases and applications
Supports hybrid deployment and resource scheduling for RDS instances and applications.
Facilitates the deployment of your O&M tools and monitoring systems.
Connects applications and databases on the same host with zero network latency.
Lightweight database hosting service
Provides database kernels, such as AliSQL and MaxScale, and supports custom deployment.
Provides flexible resource configuration and scaling based on the elastic features of cloud databases.
Provides management features such as backup and restore, high availability, and monitoring and alerting.
Full compatibility with self-managed database systems
