Database Autonomy Service (DAS) provides a layered suite of services — from free infrastructure monitoring to AI-driven autonomous management — so you can match the level of intelligence and automation to your database's needs.
What's new
DAS has restructured its product suite with three key changes:
Clearer service tiers: Basic Service remains free. Advanced O&M capabilities (transaction lock analysis, automatic SQL optimization, automatic SQL throttling) are now part of Alibaba Cloud Managed Services. Security features (whitelist management, sensitive data detection) are now consolidated into Security Services.
DAS Agent: A fully managed, AI-driven database management assistant that orchestrates all enabled services to deliver automated diagnostics, O&M, and security management across cloud, self-managed, and cross-cloud databases.
Enhanced Audit Log Service: The compliance audit tier now adds multi-AZ backups, long-term log retention, and support for personal information protection regulations, Multi-Level Protection Scheme (MLPS), and regulations outside China.
