Why choose ApsaraDB RDS

Secure, stable, and reliable

  • Proven reliability: Trusted by hundreds of thousands of users for stable business operations and battle-tested during high-concurrency, large-data events like the Double 11 Global Shopping Festival.

  • High availability: Guarantees up to 99.99% availability with a primary/secondary architecture, automatic failover, and cross-availability zone disaster recovery.

  • Backup and recovery: Provides automatic backups and supports features like cross-region backups and point-in-time recovery.

  • High security: Offers multiple security features, including network isolation, data encryption at rest and in transit, and access controls.

Simplified operations

  • Rapid deployment: Provision a database instance in minutes with a few clicks or an API call. No need to purchase hardware or software in advance.

  • Effortless maintenance: Alibaba Cloud automates software patching, backups, monitoring, failover, and replication, allowing you to focus on your business.

  • Elastic scaling: Easily scale resources up or down with a brief 30-second transient interruption or none at all. Serverless instances scale automatically in seconds without interruption.

Cost-effective

  • Flexible billing: Choose the pay-as-you-go option for short-term use and release resources when they are no longer needed. For long-term use, select a subscription to receive discounts.

  • Savings plan: A discount plan for pay-as-you-go ApsaraDB RDS resources. Compared to the pay-as-you-go billing method, you can save 20% to 70% on ApsaraDB RDS for MySQL, and 15% to 60% on ApsaraDB RDS for PostgreSQL and ApsaraDB RDS for SQL Server.

  • Serverless:

    • Automatic scaling with per-second billing can save up to 70% on costs.

    • Achieved the highest "Advanced" rating in the CAICT (China Academy of Information and Communications Technology) Serverless capability assessment.

    • New and existing users receive a 50% discount when they provision ApsaraDB RDS Serverless instances.

  • Instance suspension: Some instances can be suspended. During the suspension period, you pay only for storage. Serverless instances also support automatic start and stop.

  • Yitian edition: The new ApsaraDB RDS for MySQL Basic series offers 1-core 1 GB and 1-core 2 GB specifications. Monthly subscription prices for these instances are as low as 18 CNY and 24 CNY, respectively, with even greater discounts for annual subscriptions. Buy now.

  • Elastic I/O: This feature supports enhanced SSDs (ESSDs) that can automatically increase or decrease the IOPS limit without changing storage capacity. This prevents resource waste and extra costs from upgrading storage just to improve IOPS.

  • Read replicas: In Cluster Edition, secondary instances can be used as read replicas, which improves instance utilization.

  • Free trials: Free trials are available for new users. Tens of thousands of users have already used our free trials.

Self-developed enhanced features

Alibaba Cloud's self-developed AliSQL and AliPG kernels offer a range of innovations and optimizations on top of open-source databases to meet enterprise-level performance and stability requirements.

  • AliSQL provides many features similar to MySQL Enterprise Edition. For example, Binlog in Redo synchronously writes binary logs to the redo log during transaction commits to reduce disk I/O and improve performance. Statement Queue ensures execution plan stability. Inventory Hint enables fast transaction commits and rollbacks to improve business throughput. Thread Pool optimizes the concurrency control mechanism to ensure high performance in high-concurrency environments. Faster DDL improves the concurrent processing performance of online DDL operations.

  • AliPG includes many enhancements to the open-source PostgreSQL. For example, the Ganos spatio-temporal engine provides full-space data processing capabilities for indoor/outdoor, above/below ground, and static/dynamic data. TDE supports table-level encryption. The Always-confidential database feature supports end-to-end data encryption during storage, computation, and transmission. The Babelfish plug-in parses and executes SQL Server T-SQL statements. The rds_ccl plug-in uses SQL throttling to prevent excessive loads and ensure database stability.
