:Introduction to ApsaraDB RDS Custom

Overview

ApsaraDB RDS Custom is an open module of ApsaraDB RDS to manage database kernels and containers. ApsaraDB RDS Custom allows you to access the underlying operating system and database environment and provides lightweight management features to achieve compatibility with your O&M platforms. You can flexibly integrate RDS Custom instances into your self-managed management and O&M platforms and integrate RDS Custom instances with your business applications.

The following figure shows a comparison between RDS Custom instances, self-managed databases, and regular ApsaraDB RDS instances.

Benefits

• Accessible hosts and operating systems

  • Grants access to the operating system and database environments to implement independent O&M and management.

  • Supports API operations for host management. The API operations are compatible with Elastic Compute Service (ECS) API operations and can be quickly integrated into your self-managed management and O&M platforms.

  • Provides independent host instance types to help you create a unified resource pool.

• Integrated deployment of databases and applications

  • Allows you to integrate RDS Custom instances with applications and supports resource scheduling.

  • Facilitates the deployment of your self-managed management and O&M platforms and monitoring systems.

  • Interconnects your applications with your databases on your on-premises device without network latency.

• Lightweight database hosting service

  • Supports database kernels, such as AliSQL and MaxScale, and custom deployment.

  • Allows you to flexibly change resource configurations and supports resource expansion based on the elasticity features of ApsaraDB RDS.

  • Provides capabilities such as backup and restoration, high availability, and monitoring and alerting.

• Compatibility with self-managed database systems

  • Provides a customizable and controllable database environment that supports native replication and backup to implement fast data migration to the cloud.

  • Allows you to quickly build a multi-cloud database deployment environment for self-managed databases or databases on third-party clouds.

  • Allows you to install agents, O&M scripts, and database extensions for full compatibility with your self-managed management and O&M platforms.

Scenarios

• Database environments are customizable and controllable.

• High resource scalability is required.

• Compatibility with existing O&M platforms is required.
