Product Introduction
Native replication instances are cost-effective, self-managed solutions developed by Alibaba Cloud for the cloud-native era. This deployment model offers a new approach for ApsaraDB RDS for MySQL instances.
Through kernel innovations and multi-layer control capabilities, Alibaba Cloud has achieved key technical features including network protocol compatibility and permission system integration. This enables you to directly use MySQL native replication commands for data synchronization and topology management. The solution deeply integrates the flexibility of MySQL native replication with the stability and reliability advantages of cloud databases. You can freely control database replication topology, seamlessly integrate self-managed databases with cloud database resources, and achieve collaborative management while enjoying the convenience of the cloud ecosystem.
For database architecture building, management, disaster recovery, and other scenarios, the native replication feature provides highly compatible, secure, stable, and sustainable solutions. Through the deployment mode of "retaining core systems in self-managed data centers + elastic expansion in the cloud," it ensures both autonomy and business continuity.
Benefits
Value
High compatibility: Fully compatible with MySQL native replication commands, easily integrating with existing self-managed MySQL database environments, management platforms, and open-source tools such as Orchestrator.
Enhanced autonomy: Opens advanced permission commands such as
CHANGE MASTERandSTART SLAVE, supports self-management of replication topology and nodes with diverse topological configurations such as master-slave, master-master, and ring, meeting personalized database architecture requirements and achieving fine-grained control.Reduced costs: Based on MySQL native replication capabilities, without relying on third-party tools or complex configurations, significantly reducing construction and management costs.
Security and reliability: Inherits the stability and security of Alibaba Cloud RDS, supports automatic backup mechanisms, and provides secure and stable database services.
Multi-cloud connection: Breaks through cloud platform limitations, achieves mutual backup of databases with heterogeneous environments such as AWS, Azure, and data centers, enhances cross-cloud disaster recovery capabilities, avoids vendor lock-in, and ensures business continuity and flexibility.
Core capabilities
Hybrid architecture construction: Supports database networking across data centers, ECS, RDS, and other cloud platforms, achieving transaction-level precise control through
GTID_NEXT.Intelligent O&M system: Provides visualization of replication status monitoring, integrates DMS whiteboard management and DAS intelligent diagnostics, and supports online scaling and kernel version upgrades.
Deep ecosystem integration: Compatible with RDS backup services and big data analysis systems, quickly responding to business changes through automatic scaling.
Billing
The fee for a native replication instance equals the fee for a new RDS instance running MySQL on RDS Basic Edition. If you enable the native replication feature for an existing RDS instance, no additional fees are generated. For more information about the fees of new RDS MySQL instances, see Billable items.
Scenarios
Disaster recovery
You can mutually back up data between cloud services and data centers or between Alibaba Cloud platforms and third-party cloud platforms. If the primary database fails, you can quickly switch your workloads over to the secondary database to minimize service downtime.
Smooth migration
You can use the native replication feature to migrate data from your self-managed MySQL database on your Elastic Compute Service (ECS) instance or in your data center. This simplifies the migration process and reduces risks. For example, you can use the RDS backup to cloud and native replication features to smoothly migrate self-managed MySQL databases to the cloud. For more information, see Create a secondary database in the cloud based on RDS native replication.
Cross-cloud high availability database cluster
You can quickly build a cross-cloud high availability MySQL cluster using Alibaba Cloud RDS native replication instances. You can deploy MySQL nodes with native replication capabilities on platforms such as AWS and Azure, and achieve cross-cloud disaster recovery by flexibly configuring topology relationships and failover policies.
It is compatible with data synchronization in ECS self-managed, hybrid cloud, and multi-cloud environments, and supports calling Alibaba Cloud computing resources for unified data analysis, balancing business security and elastic expansion.
Customized architecture
You can flexibly define complex topologies (such as multi-level replication and ring replication) to provide highly customized solutions.
Cloud resource integration
Using Alibaba Cloud ecosystem tools, the native replication feature can enhance cluster functionality and simplify O&M, achieving efficient resource utilization.
For example, you can use RDS backup tools to automatically perform full backups, use DAS for operation auditing and fault analysis, manage instances using RDS's own version upgrade and rapid scaling capabilities, or use Alibaba Cloud big data services for data analysis.
